== L1® Systems and the Bose® approach to live sound ==<br />
=== How does the Bose® approach to live sound work? ===<br />
The {{L1}} system represents an entirely new approach to live amplification. In this approach, the mixer, PA speakers, monitors and backline amplifiers are replaced by special Cylindrical Radiator® loudspeakers located behind the musicians. These speakers have the unique ability to disperse sound evenly across the stage and into the audience with very little change in sound level. <br />
<br />
The Bose approach mimics the wide sound stage of many acoustic performances: Each player has control over his or her individual sound, and a group's sound comes from multiple directions corresponding to the musicians' positions on stage. This property of acoustic music enhances our ability to hear and appreciate individual instruments and voices in ensemble passages.<br />
<br />
=== Is this technology better suited for seasoned musicians who already have tons of gear, or for musicians who are just getting started and need a simple solution?===<br />
{{L1}} systems are equally valuable for seasoned musicians and beginners. Experienced performers immediately recognize they can hear better and therefore play better, and they instantly appreciate the easy setup. Inexperienced musicians can spend more time playing and less time hassling with equipment. {{L1}} systems can help them develop into better players precisely because they can hear themselves and each other better. Musicians at all skill levels benefit from knowing the sound they produce on stage is the same sound that's projected to the audience.<br />
<br />
=== Are there similarities between an {{L1}} system and line arrays currently in use? ===<br />
Line arrays have been used for large concert performances as the PA component of a traditional amplification system. Unlike these large-venue systems, an {{L1}} system is designed as a portable implementation of a line source, positioned behind a musician?providing accurate coverage for the performer, other musicians onstage and audiences.<br />
<br />
=== In nightclubs you normally see very large loudspeakers for bass. How do your smaller bass enclosures compare? What makes them so special? ===<br />
Because our bass modules are used in an integrated {{L1}} system (with amplification and signal processing), performance can be enhanced in ways conventional component-based solutions can't. At the same time, the B1 bass module is modular, making it easier to produce higher bass output for instruments and styles that require it. An upright bass in a jazz trio might need only one bass module, but the electric bass in a 10-piece funk band might use four.<br />
<br />
=== Are sound operators required with {{L1}} systems? ===<br />
No. When musicians are in control of their own amplification with {{L1}} systems?and they know the same sound they're creating onstage is projected evenly to the audience?they're well equipped to create the desired balance of voices and instruments themselves. Without assistance from sound operators.<br />
<br />
=== What happens if a musician is blocking the view of an {{L1}} system? Doesn't that block the sound? ===<br />
Sound can diffract (bend) around objects. As long as a musician isn't standing directly against the {{L1}} loudspeaker, the sound diffracts around the musician and other objects like a keyboard or instrument. <br />
<br />
=== How loud can an {{L1}} system play? ===<br />
The new approach can compete with the maximum levels created by most conventional amplification systems. What's changed is that musicians in a band will rarely, if ever, struggle to hear themselves and each other, eliminating a major reason for excessive volume levels. With the new approach, dynamics are vastly improved, contributing greatly to musical quality. In testing at Bose, musical groups plagued by the problem of excessive loudness were delighted to find that, in one or two sessions, their average volume level had dropped drastically while their peak level remained the same. They expressed an enormous increase in the enjoyment of playing, and audiences expressed appreciation for music that was exciting but not overwhelmingly loud.<br />
<br />
=== Is this really a "plug and play" solution? How long does it take to set up? ===<br />
{{L1}} systems disassemble into easy-to-carry pieces. Everything can be carried by hand with no need for special equipment. The systems are also designed for easy assembly in just a few minutes. No group mixing is required with {{L1}} systems, eliminating the task of wiring instruments to a mixer, then from mixer to amplifiers and speakers. Musicians simply set up their {{L1}} systems, plug in and they're ready to play.<br />
<br />
=== Does every musician in the band need his or her own {{L1}} system? ===<br />
No. In some situations?a larger ensemble on a small stage, for example?testing showed that two or more musicians standing or sitting next to each other could share one {{L1}} system without a significant erosion of the benefits of the approach.<br />
<br />
=== Can one musician use an {{L1}} system while the rest of the band plays through a conventional system? ===<br />
Yes?there are two ways. A performer can use an {{L1}} system onstage without connecting to any other house reinforcement equipment, including stage monitors and main front speakers (or "house mains"). This allows the musician using the {{L1}} system to hear himself better and to be heard better by the other musicians onstage as well as the audience.<br />
<br />
A performer can also use an {{L1}} system onstage while sending his or her audio<br />
signal(s) to a house PA. In this case, the musician and the band enjoy the benefits from the {{L1}} system's sound onstage only. There are no advantages for the audience. The potential for excessive reverberation and the problems of bulky and complex equipment continue to exist when the rest of the band plays through a conventional setup.<br />
<br />
=== Can acoustic instruments be amplified with an {{L1}} system? ===<br />
Yes. If the acoustic instrument has a pickup system, you can connect to an {{L1}} system's power stand or into a ToneMatch® audio engine. When pickups aren't present, a microphone may be used. An {{L1}} Model I power stand is equipped with 24V phantom power capability for channels 1 and 2 to power condenser microphones. With a Model II system, use a direct box or transformer to adapt the mic cable to the power stand's 1/4" analog input connector. <br />
<br />
=== How does this approach work for electric guitar? ===<br />
There are three main ways an electric guitar's tone can be included in the {{L1}} system approach.<br />
<ul><br />
<p><b>With a modeling amp. </b>An electric guitarist simply plugs into a modeling amp, then plugs the output of that amp into an {{L1}} system. This is the most convenient and elegant way to use electric guitar with an {{L1}} system.</p><br />
<br />
<p><br />
<b>With a preamplifier.</b> Most tube-based or solid-state guitar preamplifiers can be used with an {{L1}} system. Just plug the output of the preamp directly into the {{L1}} power stand or ToneMatch audio engine.<br />
</p><br />
<p><br />
<b>With a traditional guitar amplifier.</b> Place a microphone in front of a traditional tube amplifier and connect the mic cable to an input on the L1. Exceptional results have been obtained with the use of low-wattage tube amplifiers— increasingly popular with players who want the tone of a tube amp without producing extremely high sound levels onstage.</p><br />
<br />
</ul><br />
<br />
The advantage gained in these methods constitutes what is arguably the most important advance in electrical guitar sound since the invention of the guitar amplifier itself: The L1® Cylindrical Radiator® loudspeaker overcomes the problem of uneven sound dispersion experienced with traditional guitar amps. The dispersion pattern of a typical guitar amp can be so harshly directional that the sound may be painful to listeners right in front of the amp speaker, but dull and muddy to others off to the sides. With an {{L1}} system, the sound a guitarist hears onstage is dispersed evenly and clearly throughout the audience.<br />
<br />
=== How does the output of an {{L1}} system compare to a loud stack of guitar amplifiers and cabinets? ===<br />
The output of an {{L1}} system can compete effectively with the output of a full stack of guitar amps and cabinets. There are additional benefits that distinguish an {{L1}} system from a full stack's acute directional beam, including the wide, even sound coverage of the Cylindrical Radiator® speaker. An {{L1}} system can also be used to amplify other instruments and voices at the same time<br />
<br />
=== Can you create distortion for guitars with an {{L1}} system? ===<br />
No, but you can amplify distorted sounds through an {{L1}} system. Distortion must be produced first, then fed into an {{L1}} power stand as a non-clipping signal. Key ways to do this:<br />
<br><br />
<br />
<ul><br />
<br />
<p><b>Use inline devices.</b> Overdrive/distortion effects pedals and DSP-based amplifier modelers can be used effectively with {{L1}} systems.</p><br />
<br />
<p><b>Mic a guitar amplifier.</b> Mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest possible level to attain the desired tone without diminishing {{L1}} system benefits. Small, low-watt amplifiers can be used onstage; louder amplifiers can be located offstage. </p><br />
<p><br />
<b>Use a loading device.</b> Some electric guitarists may prefer to use their amplifier's output as an input signal into the power stand. Before doing this, you must use a load device such as a "plate soak" or a "hot plate" to produce a line-level output suitable for the input stage of the power stand.</p><br />
<br />
<p><br />
<b>Use the line output of a guitar amplifier.</b> This option may be suitable for some guitarists. Turn the amplifier volume down so only the {{L1}} system is heard. <br />
</p><br />
<br />
</ul><br />
<br />
=== Where can an {{L1}} system be used? ===<br />
An {{L1}} system is suitable for amplified music performances in venues with occupancies up to 500 people. Typically this translates to maximum listener distances of about 150 feet (45 meters). The system will fill venues where the vast majority of live music performances take place, including small auditoriums, places of worship, gymnasiums, ballrooms, clubs and coffeehouses. Tests show that in larger venues, a musical group can use the {{L1}} systems onstage and enjoy the benefits of hearing themselves and each other better. Signals from the stage can then be fed to speakers that supply sound to distant seating areas.<br />
<br />
=== Can I use the system outside? ===<br />
<section begin="temperature" /><br />
Yes. The system has been tested to operate in 32°F to 122°F (0°C to 50°C) temperatures; it can also be stored in -22°F to 158°F (-30°C to 70°C) temperatures. Take precautions in light rain to cover the back panel of the power stand. Keep water out of the air inlet slits inside the back panel, on the loudspeaker drivers or inside the {{L1}} cavity on the power stand.<br />
<section end="temperature" /><br />
<br />
=== Can DJs benefit from this system? ===<br />
Yes, this system offers important advantages over conventional systems for DJs. One problem with portable PA systems is their stand-mounted speakers are very loud close to the speaker, and not loud enough away from it. With the L1® Cylindrical Radiator® loudspeaker, you can adjust for the desired volume level on the dance floor and in the audience, and then walk right up next to the speaker without it getting excessively loud—translating into much greater comfort for listeners. The system also has a sleek, elegant profile that fits nicely into event décors and minimizes sightline issues. And it's easier to transport, set up and break down than most portable PA systems.<br />
<br />
=== Can {{L1}} systems be used as a traditional PA? ===<br />
Yes. {{L1}} systems can be used to replace PA speakers. Their unique radiation properties help them deliver more even sound coverage and a larger stereo field?benefits confirmed in listening tests. Compact size is also an advantage for transport and rapid setup/breakdown. <br />
<br />
=== Are {{L1}} systems prone to feedback? ===<br />
L1 systems are resistant to feedback, but not immune from it. Putting a live mic right up against the loudspeaker, for example, will create feedback. But in the vast majority of cases, {{L1}} performance in this critical area has proven to be significantly better than the traditional use of separate backline amplifiers, monitors and PA systems. <br />
<br />
=== Can I use two-wire Speakon® cables for the B1 bass modules? ===<br />
No. Only four-wire Speakon cables should be used with the power stand. The additional two wires (+2 and -2) in the connector are used for sensing purposes. With the four-wire cable, the power stand can sense and adjust (EQ and level) for 0, 1 or 2 connected bass modules.<br />
<br />
=== How can I tell if I'm using the correct four-wire Speakon cable for bass module connections? ===<br />
When you plug a four-wire Speakon cable into an {{L1}} system while music is playing, you will clearly hear the loudspeaker mute for a moment. If you're using an incorrect cable, the momentary muting won't occur.<br />
<br />
=== Can I connect a passive subwoofer to the bass module output? ===<br />
No. We don't recommend connecting anything to this output except a B1 bass module, as the internal amplifier and bass module(s) are designed to properly equalize the system when connected. You may use the bass line-out connection, however, to feed a powered subwoofer or additional amplifier.<br />
<br />
=== Can I use the bass line out to connect to a bass amplifier and cabinet? ===<br />
Yes. The bass line-out connector provides a flat 40 Hz to 180 Hz bandpass signal when no B1 bass modules are connected. We recommend unplugging the bass modules to ensure correct EQ compensation of the bass line-out jack and phase consistency.<br />
<br />
=== Why does the sound coming from an {{L1}} system change when I plug a 1/4" cable into the bass line-out connector? ===<br />
L1 systems produce audio in the range of 110 Hz to 18,000 Hz when the bass line-out jack is not in use. The frequency cutoff point moves from 110 Hz to 180 Hz when you plug a cable into the bass line-out jack, accounting for the tonal change you're hearing.<br />
<br />

<br />
<br />
=== What about using just the lower half of an {{L1}} system's loudspeaker in places where the ceiling isn't tall enough for full assembly? ===<br />
You can do it, but using only half of an {{L1}} loudspeaker will significantly impact system performance. The EQ will be incorrect, and sound coverage decreased. Plus, in order to hear yourself properly, it's best to have your ears at the same height as some part of the loudspeaker—which may be difficult unless you're seated. <br />
<br />

<br />
=== There's a buzz in the system. Any suggestions on how to fix it? ===<br />
Most times, noise you hear through an {{L1}} system is caused by outboard gear and power sources, not the system itself. One of the most effective ways to alleviate buzz and hum in any system is to plug all interconnected gear into the same electrical circuit. Guitar players or vocalists with effects should plug them into the same electrical outlet as the power stand. This normally fixes all problems. A power strip may be helpful, but avoid using three-prong to two-prong adapters, also known as "cheaters" or "ground lifters." Bypassing a safety grounding mechanism is a serious safety threat.<br />
<br />
Noise and buzzing are common problems with pro audio gear. But the new Bose approach to live sound can dramatically reduce gear noise because it uses a simple, independent system. The typical buzzes and hums associated with ground loops are eliminated when you use an independent system that's not electronically connected to other equipment.<br />
<br />
=== Why doesn't Bose publish full system specifications for {{L1}} systems? ===<br />
While some specifications add value when comparing two otherwise similar products, they're mostly meaningless for a product as fundamentally different as the Cylindrical Radiator® loudspeaker and the {{L1}} system. In addition, most specifications used to describe sound systems can be very misleading. They suggest relatively complex physical or perceptual properties can be condensed to a single or small set of numbers that defines overall quality or performance. In many cases these numbers only loosely relate to what you would experience in a real-world application. <br><br> There are also several variations in how a specific measurement can be carried out, making number comparisons useless. We believe it serves our customers better to describe {{L1}} systems in terms they can relate to more directly. We also encourage customers to experience an {{L1}} system personally, either at a demonstration or in actual real-world trials they conduct themselves. <br />

<br />
=== What exactly are ToneMatch® presets and what are the benefits of using them? ===<br />
Skilled studio engineers listened to the sound of specific instruments and microphones being played through an {{L1 nl}} system, made adjustments to improve the sound quality and then saved those settings as ToneMatch presets. Now the high level of tone customization most musicians experience only in recording studios is instantly available at your live performances. Sound check can be as simple as plugging in your instrument or mic and selecting the appropriate ToneMatch preset.<br />
<br />
=== What is the proper method for setting gain on an {{Model I}} power stand? ===<br />
There are three gain settings for the primary channels (1 and 2) and two gain settings for the secondary channels (3 and 4). To set the gain for the primary channels 1 and 2:<br />
<br />
<ul><br />
<li style="list-style-type: decimal;">Adjust the input gain<br>Set the trim for the individual channel at the back panel of the power stand. Supply a maximum source signal and watch the LED. When you start to see it flash red, back off slowly on the trim knob until it flashes green again.<br />
</li><br />
<br><br />
<li style="list-style-type: decimal;"><br />
Adjust the channel gain with the R1 remote control<br> <br />
With the master at zero, set the respective channel gain to 6. At this point, the LED on the remote will be at the same intensity as the LED on the back panel of the power stand. This is considered optimum gain. You then can add a bit more channel gain on the remote if it's required.<br />
</li><br />
<br><br />
<li style="list-style-type: decimal;"><br />
Set the remote master gain<br>The remote master knob is the last stage of gain. This knob gives you control over all four channels of the power stand.<br />
</li><br />
</ul><br />
<p><br />
<br />
To set the gain for channels 3 and 4 simply adjust the input gain of the individual channel. These channels don't have indicator LEDs, but are designed for 0 dB line-level signals (e.g., from an effects device, mixer or MP3 player). Use the remote control master knob as the last stage of gain for these channels.<br />
</p><br />
<br />
=== What is the recommended way to set the gain for a Model I system when using it with a T1 ToneMatch audio engine? ===<br />
* Make sure the power switch on the power stand is in the Off position and the remote control is disconnected<br> <br />
<i>Note: The remote should be disconnected so that the ToneMatch audio engine solely controls the volume of the {{L1 nl}} system.</i><br />
* Make sure the ToneMatch audio engine power switch is in the Off position and its power supply is connected<br />
* Set the ToneMatch audio engine master volume control to 0<br />
* Plug one end of a 1/4" phone plug cable (not supplied) into the master output port on the ToneMatch audio engine. Plug the other end of the cable into the line-in jack of channel 3 or 4 on the {{L1 nl}} power stand <br /><i><br />
Note: We recommend only connecting to the line inputs of channels 3 and 4 because channel 1 and 2 mic/line inputs have volume controls, equalization and presets that could affect the ToneMatch audio engine's sound and performance.</i><br />
* Set the line-in level control on the power stand to approximately 2 <br /><i>Note: In some circumstances, it may be necessary to slightly adjust the level of this initial setting to attain the desired gain structure.</i> Note: Bose has revised this, and now recommends setting the level control to approximately '''3'''. <br />
<br />

*Turn on the {{L1 nl}} power stand <br />
<br />
=== Do the mic inputs have phantom power? ===<br />
Yes. The primary input channels 1 and 2 have a button selector for +24V phantom power for microphones that require it.<br />
<br />
=== I thought phantom power was 48 volts. Why does the power stand only supply 24 volts? ===<br />
Phantom power is a DC voltage that powers the preamplifier of a condenser microphone. It can be in a range of 11 – 48 volts.<br />
<br />
=== What input connections will channels 1 and 2 accept? ===<br />
Channels 1 and 2 accept two types of input connections: a balanced XLR (mic) connection and a 1/4" phone connector unbalanced (line) input for instruments<br />
<br />
=== Why don't channels 3 and 4 have presets, XLR inputs and line outs like channels 1 and 2? ===<br />
The {{L1 nl}} Model I system was designed with the individual musician in mind. Primary inputs 1 and 2 are intended to receive signals from an instrument and a vocal mic. Each musician's instrument and voice can be heard through his or her own {{L1 nl}} system. The remaining channels are suitable for additional direct instruments, mixers and MP3 or CD players.<br />
<br />
=== What are the critical frequencies (Q-points) of the remote control? ===<br />
The mid control is centered about 1.2 KHz with a Q of approximately 1. High and low responses are shelving. We don't quote shelving frequencies because there's no clear industry standard definition of a shelf's "cutoff frequency."<br />
<br />
=== Will an {{L1 nl}} Model I system still work without the remote control? ===<br />
Yes, but it's not recommended. If you turn on the power stand without the remote connected, it will operate as if the remote were connected with all control knobs at the center position. Alternately, if you turn on the power stand with the remote connected and you then disconnect the remote, the power stand will retain the last settings of the remote before you disconnected it.<br />
<br />
=== Is the remote control cable an off-the-shelf MIDI cable? Are there extensions available? ===<br />
The remote uses a special 7-pin DIN cable commonly referred to as a "7-pin phantom MIDI cable." This cable configuration is sometimes used to connect rack-mount guitar effects to their pedals. A standard 5-pin MIDI won't work. Bose sells a 7-pin DIN (20') replacement cable. <br />
<br />
=== Does the remote use MIDI-compatible commands? Can I automate remote functions using MIDI communications protocol? Can I customize my settings using the remote port on the power stand? ===<br />
The remote control and associated hardware are proprietary and don't use MIDI communications protocol. The remote control port on the power stand won't function with standard MIDI products.<br />
<br />
=== Does an {{L1 nl}} Model I system have built-in effects? ===<br />
No. There are connectors, however, for inserting effects units into channels 1 or 2 of the power stand. These connectors require standard insert cables with 1/4" TRS connections on one end and dual male 1/4" TS connectors on the other. You may also purchase a Bose ToneMatch audio engine, which includes a complete suite of studio-class effects and processing.<br />
<br />
=== Can I use effects equipment with the {{L1 nl}} Model I power stand? ===<br />
Channels 1 and 2 allow for a TRS line input/output connection for external effects units. Inserting the plug halfway connects to "Send;" inserting fully connects to "Return." Some musicians may prefer to keep a "dry" sound intact without the full effects loop; inserting the plug halfway into the connector will maintain the original signal and not route the channel solely through the effects module. You can use either a serial or parallel connection for effects units, as detailed in the owner's guide. In addition, you may also use a Bose T1 ToneMatch audio engine with an {{L1 nl}} system. It features a complete suite of studio-class effects and processing.<br />
<br />
=== How can I add more inputs to my system? ===<br />
Use our multichannel {{T1}}, specifically designed for {{L1 nl}} systems. It offers three mic/line inputs, two line inputs (L/R), our largest library of ToneMatch presets, proprietary zEQ and a complete suite of studio-class effects and processing. Simply connect the ToneMatch audio engine via an analog 1/4" TS cable from its master output to channel 3 or 4 of the {{L1 nl}} Model I power stand.<br />
<br />
=== What's the "data out" connector for? ===<br />
This is a SPDIF connection for digital recording of channels 1 and 2. It runs at a sample rate of 48 kHz. Channels 3 and 4 aren't included in this output.<br />

==The Technology==<br />
<br />
=== What is the {{L1 nl}} Model I system? ===<br />
<br />
The {{L1 nl}} Model I system represents a new approach to amplification. This approach was designed to address the root cause of complaints by musicians and audience members regarding the quality of live amplified musical performances.<br />
<br />
=== How does this approach work? === <br />
<br />
In the new approach mixer, PA speakers, monitors and backline amplifiers (e.g. guitar amps) are replaced by special Cylindrical Radiator® loudspeakers, which are located behind the musicians. These speakers have the unique ability to radiate sound evenly across the stage and into the audience with very little change in sound level.<br />
<br />
The approach is naturalistic in that it mimics an acoustic instrument performance: Each player has control over his or her individual sound, and the sound comes from the multiple directions that correspond to the musician<nowiki>’</nowiki>s positions on stage – a property of acoustic music known to enhance our ability to hear and appreciate individual instruments and voices in ensemble passages. The new approach has many integrated features that allow the user to set up the system in just minutes.<br />
<br />
=== Is this technology better-suited for seasoned musicians who already have tons of gear, or for musicians who are just getting started and need a simple solution? === <br />
<br />
The system is equally valuable for the seasoned musician and the beginner. Experienced performers immediately will recognize that they can hear better and therefore play better, and they instantly appreciate the easy setup. Musicians who are starting will enjoy playing more because they<nowiki>’</nowiki>ll spend<br />
<br />
more time playing and less time hassling with equipment. They will develop as better players because they can hear themselves and each other. All will benefit from the knowledge that the sound they produce on stage is what is radiated to the audience. Never again will they hear and think one thing, only to find out the audience heard something completely different when they asked "How did we sound?" after the performance.<br />
<br />
=== What is the concept behind ToneMatch™ presets, and what are the benefits? === <br />
<br />
ToneMatch™ presets make it easy to get exceptional amplified tone from any voice or instrument when used with Bose® {{L1 nl}} portable line array systems. When you select a proprietary ToneMatch preset for your microphone or instrument, you are tapping into a powerful new technology available only from Bose. A skilled studio engineer listened to the sound of your instrument being played through an L1 system, made adjustments to improve the sound quality and then saved those settings as a ToneMatch preset.<br />
<br />
Now the high level of tone customization that most musicians experience only in a recording studio is available on stage at your live performances. Sound check can be as simple as plugging in your instrument or microphone and selecting the appropriate ToneMatch preset.<br />
<br />
=== Are there similarities between the {{L1 nl}} Model I system and line arrays currently in use? === <br />
<br />
Line arrays have been used for large concert performances as the PA component of a traditional triple amplification system. Unlike these large-venue systems, the {{L1 nl}} Model I system is designed as a portable implementation of a line or pole-shaped source. It is designed to be positioned behind each musician, providing accurate coverage for musicians and audiences.<br />
<br />
=== In nightclubs, you normally see very large loudspeakers for bass. How do your smaller bass enclosures compare? What makes them so special? === <br />
<br />
Bose has a number of propriety technologies for bass and has a long history of developing systems that produce high output in the bass range from smaller enclosures. The B1 bass module is no exception. The fact that it is used in an integrated system (with amplification and signal processing) means that performance can be enhanced in ways that a conventional component-based solution cannot. Large signal performance, for example, can be greatly improved with the use of a dedicated digital signal processor, which is built into the Model I power stand.<br />
<br />
At the same time, the B1 bass module has been made modular, so that higher bass output can be created for instruments and styles that require it. An upright bass in a jazz trio might use only one bass module. On the other extreme, the electric bass in a 10-piece funk band might use four.<br />

=== Does Bose plan to add to the {{L1 nl}} product family? === <br />
<br />
In the spring of 2007, Bose announced the introduction of the {{L1 nl}} Model II system. This system has many similarities to the {{L1 nl}} Model I and features the introduction of the {{T1 nl}}. To learn more about the benefits and features of {{L1 nl}} Model II system please visit [http://www.bose.com/musicians www.Bose.com/musicians].<br />
<br />
=== I already own an {{L1 nl}} Model I or Model II system. Can I purchase the T1 separately and use it with the system? === <br />
<br />
Yes. The T1 is available for purchase separately and may be used with either an {{L1 nl}} Model I or Model II system. When used with a Model II system, the audio is connected digitally via the ToneMatch™ ports. When used with a Model I, a separate power supply is required to power the T1 and the audio is analog. When using with a Model I, simply connect the T1<nowiki>’</nowiki>s Master Output jack to the analog input of Channel 3 or 4 on the Model I power stand. The T1 power supply is available through Bose or authorized dealers of the L1 family of products.<br />
<br />
=== When will additional products be added to the {{L1 nl}} product family? === <br />
<br />
We do not publicly discuss new products before their launch date. Our engineers and marketing staff are always researching new solutions for musicians, and we are dedicated to offering products of enduring value.<br />
<br />
=== Are hard-shell cases available for the products? === <br />

<br />
== Functionality ==<br />
<br />
=== Is this really a "plug and play" solution? How long does it take to set up? === <br />
<br />
The {{L1 nl}} Model I system is designed to disassemble into easy-to-carry pieces. Everything can be carried by hand without the need for special equipment. Moreover, the products are designed to assemble in just minutes, and because the approach requires no mixing, the complex task of wiring each instrument to the mixer and then from the mixer to the amplifiers and speakers is eliminated. The musicians simply plug in, and they<nowiki>’</nowiki>re ready to play.<br />
<br />
=== Are sound operators required in the new approach? === <br />
<br />
No. Just as acoustic-instrument ensembles (such as a string quartet) are able to balance their own sound, so too can a group playing amplified music using the new approach. The reason is that when musicians are in total control and know that the sound they are creating on stage is what is radiated outward to the audience, they are best-suited to creating the required balance of voices and instruments.<br />
<br />
=== What happens if a musician is blocking the view of the {{L1 nl}} Model I system? Doesn<nowiki>’</nowiki>t that block the sound? === <br />
<br />
Sound diffracts (bends) around objects. So long as the musician is not standing literally against the {{L1 nl}} Model I system, the sound diffracts around the musician or other objects such as a keyboard or other musical instrument.<br />
<br />
=== What is the proper method for setting gain on the {{L1 nl}} Model I power stand? === <br />
<br />
There are three gain settings for the primary channels (1 and 2) and two gain settings for the<br />
<br />
secondary channels (3 and 4).<br />
<br />
'''To set the gain for the primary channels (1 or 2):'''<br />
<br />
1) Adjust the input gain. Set the trim for the individual channel at the back panel of the power stand. Supply a maximum source signal and watch the LED. When you start to see it flash red, back off slowly on the trim knob until it flashes green again.<br />
<br />
2) Adjust the channel gain with the R1 remote control. With the master at zero, set the respective channel gain to 6. At this point, the LED on the remote will be at the same intensity as the LED on the back panel of the power stand. This is considered optimum gain. The musician then can add a bit more from the R1 remote control if it is required.<br />
<br />
3) The R1 remote control MASTER knob is the last stage of gain. This knob gives you control over all four channels of the power stand.<br />
<br />
=== What is the recommended gain staging for Model I systems when using with a T1? === <br />
<br />
1. Make sure the '''Power '''switch on the power stand is in the OFF position and the R1 remote control is disconnected.<br />
<br />
'''Note:''''' The R1 remote control should be disconnected so that the {{T1 nl}} solely controls the volume of the {{L1 nl}} Model I system.''<br />
<br />
2. Make sure the T1 power switch is in the OFF position and the T1 audio engine power supply is connected.<br />
<br />
3.''' '''Make sure the T1''' Master '''volume control is set to '''0'''.<br />
<br />
4. Plug one end of a ¼" phone plug cable (not supplied) into the '''Master '''output port on the T1. Plug the other end of the ¼" phone plug cable into the Channel 3 (or Channel 4) Line IN jack on the L1 power stand.<br />
<br />
5. Set the Line IN '''Level '''control on the power stand to approximately '''2'''. NOTE: This setting has been revised to '''3''' or '''4''' ref: [[T1_ToneMatch%E2%84%A2_Audio_Engine#Power_Stand_Input_Setting|T1 ToneMatch&trade; Audio Engine: Power Stand Input Setting]]<br />
<br />
6. Turn on the T1 audio engine.<br />
<br />
7. Turn on the L1 Model I power stand.<br />
<br />
'''Note:''''' In some circumstances, it may be necessary to slightly adjust the Line IN '''Level '''control from this initial setting to attain the desired gain structure.''<br />
<br />
Because the Channel 1 and 2 Mic/Line inputs on the power stand have volume controls, equalization and ToneMatch™ presets that could affect the sound and performance of a T1, we only recommend connecting to the Channel 3 and 4 line inputs.<br />
<br />
Adjusting gain for Channels 3 or 4<br />
<br />
1) Adjust the input gain of the individual channel. These channels do not have indicator LEDs but<br />
<br />
are designed for 0 dB line level signals, such as from an effects device, mixer or CD player.<br />
<br />
2) As above, the R1 remote control MASTER knob is the last stage of gain. This knob gives control over all four channels of the {{L1 nl}} Model I power stand.<br />
<br />
=== Can I use the Bass - Line OUT on the {{L1 nl}} Model I system to connect to a bass amplifier and cabinet? === <br />
<br />
The bass-line-out connector provides a flat 40-Hz to 180-Hz bandpass signal when no B1 bass modules are connected. We recommend unplugging the B1 bass modules to ensure correct EQ compensation of the Bass - Line OUT jack and phase consistency.<br />
<br />
=== Is the R1 remote control cable an off-the-shelf cable? Is this a standard MIDI (Musical Instrument Digital Interface) cable? Are there extensions available? === <br />
<br />
The remote uses a special 7-pin DIN cable commonly referred to as "7-Pin Phantom MIDI Cable." This cable configuration is sometimes used to connect rack-mount guitar effects to their pedals. A standard 5-pin MIDI will not work. Bose sells the 7-pin DIN (20-foot) replacement cable. For those customers needing a little extra distance from their power stand to their R1 remote control, Hosa Technology, Inc., manufactures 25-foot cables. These sell at [http://www.musiciansfriend.com/ www.MusiciansFriend.com] (Product #333039). Coupler adapters are not available.<br />
<br />
=== Does the R1 remote control use MIDI-compatible commands? Can I automate remote functions using MIDI communications protocol? Can I customize my settings using the remote control port on the power stand? === <br />
<br />
No. The R1 remote control and associated hardware is proprietary and does not use MIDI communications protocol. This port will not function with standard MIDI products.<br />
<br />
=== Will the unit still work without the R1 remote control? === <br />
<br />
Yes. The power stand continuously senses activity at all preset selectors and what is connected at the input/output jacks. In general, it is not recommended to operate without the remote connected. However, the power stand can function without the R1 remote control. If you power the power stand on without the R1 remote control connected, it will operate as if the R1 remote control was connected and at a fixed setting of 12 o<nowiki>’</nowiki>clock (center position) on all the control knobs. Alternatively, if the unit is powered on with the R1 remote control first connected and the user then disconnects the R1 remote control, it will retain the last settings of the R1 remote control before you disconnected it. This is helpful in the case where sharing may be necessary.<br />
<br />
=== Do the mic inputs have phantom power? === <br />
<br />
Yes. The primary input channels (Channels 1 and 2) have a button selector for <nowiki>+</nowiki>24V phantom power for microphones that require that feature.<br />
<br />
=== I thought phantom power was 48 volts? Why does the power stand only supply 24 volts? === <br />
<br />
Phantom power is a DC voltage that powers the preamplifier of a condenser microphone.<br />
<br />
Phantom power can be in a range of 11-48 volts.<br />
<br />
=== How many B1 bass modules can you connect? === <br />
<br />
One power stand using an {{L1 nl}} Model I system can power up to two B1 bass modules.<br />
<br />
=== Can this product be used in other countries? === <br />
<br />
There are two voltage versions of the power stand and the A1 PackLite® amplifier. 120V versions are available in the U.S., Canada and some Latin American countries. The 230V versions are available in Europe and Australia. Please visit www.Bose.com/musicians for up-to-date information about product availability.<br />
<br />
=== How do I know which half of the Cylindrical Radiator® to insert into the power stand first? === <br />
<br />
The upper and lower halves of the {{L1 nl}} Model I system are not identical. The bottom half is easily identifiable because it has a large end cap, which gets inserted first into the power stand. The upper half contains the Bose® logo and uses a tongue-and-groove mechanism to ensure a solid mechanical and electrical connection to the lower half. Both halves are clearly labeled on the back, indicating proper insertion.<br />
<br />
=== Can you use 2-wire Speakon® cables for the B1 bass modules? === <br />
<br />
No. Only 4-wire Speakon® cables should be used with the power stand. The additional two wires (<nowiki>+</nowiki>2 and -2) in the connector are used for sensing purposes. Upon connection, the power stand is able to sense and adjust (EQ and level) for 0, 1 or 2 B1 bass modules connected to the bass module Out Speakon® connector.<br />
<br />
=== What is the Data IN connector used for? === <br />
<br />
The Data IN connector is used for updating product software.<br />
<br />
=== Can the customer update the power stand? === <br />
<br />
Yes. The customer can update the presets in the power stand. For more information about upgrading presets, please visit www.Bose.com/musicians.<br />
<br />
=== How can I tell if I<nowiki>’</nowiki>m using the correct Speakon® cable? === <br />
<br />
If you plug in a 4-wire Speakon® cable to the Bass-Amp 3 OUT connector with music playing through, you will clearly hear the {{L1 nl}} Model I system mute for a moment. If you are using an incorrect cable, such as a 2-wire Speakon® cable, the momentary muting will not occur.<br />
<br />
=== Why does the sound coming from the {{L1 nl}} Model I system change when plug in a ¼-inch plug into the Bass - Line OUT connector? ===<br />
<br />
The {{L1 nl}} Model I system receives its audio signal from the power stand. The signal is customized by the internal DSP unit according to what other devices are connected to the power stand, such as how many B1 bass modules and/or amplifiers are connected to the Bass - Line OUT connector. The {{L1 nl}} Model I system when used alone with the power stand produces audio in the range of 110 Hz to 18, 000 Hz. When the Bass - Line OUT connector is in use the frequency cutoff point is moved from 110 Hz to 180 Hz, it will not play any frequencies below 180 Hz. The Bass - Line OUT connector sends a flat bandpass signal from 40 to 180 Hz to external amplifiers that may be used for extended low frequency reinforcement.<br />
<br />
=== What<nowiki>’</nowiki>s the sample rate of the Data OUT connector? The owners<nowiki>’</nowiki> manual only mentions "Channel 1/2 digital output." === <br />
<br />
The Data OUT connector is a SPDIF connection for digital recording of both Channels 1 and 2. It runs at a sample rate of 48 kHz. Channels 3 and 4 are not included in this output.<br />
<br />
=== Why don<nowiki>’</nowiki>t Channels 3 and 4 have presets, XLR inputs and line outs like Channels 1 and 2? === <br />
<br />
The {{L1 nl}} Model I system was designed with an individual in mind, as an extension of your musical instruments. For this, we have provided two primary inputs, 1 and 2. These inputs were intended to receive signal from an instrument, such as a guitar or keyboard, and a voice. Each musician<nowiki>’</nowiki>s instrument and voice can be heard from his or her own system. The remaining channels, though still suitable for direct instruments, can be used for CD background music for playback in between performance sets.<br />
<br />
=== I need more inputs. How do I plug in all my instruments? === <br />
<br />
For some multi-instrumentalists, there may not be enough input connectors. Musicians who require additional inputs can purchase a {{T1 nl}}. The T1 is a powerful multichannel audio device designed for use with {{L1 nl}} Model I and Model II systems. It contains our largest library of ToneMatch™ presets, proprietary zEQ, and a complete suite of studio-class effects and processing.<br />
<br />
The T1 was designed with the needs of musicians in mind. This makes for a completely integrated and powerful unit that is easy to use and alleviates many challenges associated with live performances. When the T1 is used with the Model I system, the audio connects via an analog ¼" TS cable from the Master Output of the T1 into Channel 3 or 4 of the power stand.<br />
<br />
=== Does the {{L1 nl}} Model I system have built-in effects? === <br />
<br />
No. While the system does not have built-in effects, there are connectors for inserting effects units into Channel 1 or Channel 2 of the power stand. This requires a standard insert cable, which has a ¼" TRS connection on one end and dual male ¼" TS connectors on the other end.<br />
<br />
Additionally, you may purchase a {{T1 nl}}, which includes a complete suite of studio-class effects and processing.<br />
<br />
=== Can you use effects equipment with the power stand? === <br />
<br />
Yes. Both Channels 1 and 2 allow for a TRS line input/output connection for external effects processors. Inserting the plug halfway connects to "Send"; inserting fully connects to "Return." Some musicians may prefer to keep a "dry" sound intact without the full effects loop. Inserting the plug halfway into the connector will maintain the original signal and not route the channel solely through the effects module.<br />
<br />
'''Using a serial effects connection with the {{L1 nl}} Model I power stand'''<br />
<br />
'''Note'''''''':''' Connecting an effects unit in serial requires a TRS split "insert" cable (with a ¼-inch TRS connector on one side and two mono ¼-inch phone connectors on the other). This type of cable is readily available at most musical instrument stores and on the Internet.''<br />
<br />
1. Insert the TRS plug into the '''Channel 1''' Insert jack on the {{L1 nl}} Model I power stand.<br />
<br />
2. Connect the ¼-inch mono plug (labeled "send," "ring" or ""right") to the input of the effects processor.<br />
<br />
3. Connect the other ¼-inch mono plug (labeled "return," "tip" or "left") to the output of the effects processor.<br />
<br />
4. Adjust the effects level and mix of the effects processor.<br />
<br />
'''Note:''' ''A very high output from the effects processor can overload the input of the L1 Model I power stand. If the '''LED''' on the remote turns red, even if the channel '''LEVEL '''control on the R1 remote control is below the 12 o<nowiki>’</nowiki>clock position, reduce the output level of your effects processor.''<br />
<br />
'''Note:''' ''The effects processor does interrupt the audio path. This may result in no audio output if the effects processor is turned off. To use a "clean" signal, do not turn the effects processor off, but put it in bypass mode.''<br />
<br />
'''Using parallel effects connection with the {{L1 nl}} Model I power stand'''<br />
<br />
'''Note:''' Connecting an effects unit in parallel requires one ¼-inch ''unbalanced'' (instrument) cable, one mono ¼-inch phone (M) to dual mono ¼-inch phone (F) "Y" cable adapter, and one TRS split "insert" cable (with a ¼-inch TRS connector on one side and two mono ¼-inch phone connectors on the other).<br />
<br />
1. Insert the TRS plug into the '''Channel 1 Insert''' jack on the {{L1 nl}} Model I power stand.<br />
<br />
2. Connect both ¼-inch plugs from the "insert" cable into both receptacles on the "Y" cable adapter.<br />
<br />
3. Connect the plug of the "Y" cable adapter into the input of the effects processor.<br />
<br />
4. Connect the ¼-inch unbalanced (instrument) cable from the output of the effects<br />
<br />
processor to '''Channel 3 Line IN''' of the L1 Model I power stand.<br />
<br />
5. Set the effects level of the processor to full and turn the mix level of the effects processor to full "wet."<br />
<br />
6. Adjust the '''Channel 3 Level control''' of the L1 Model I power stand for the desirable effects mix.<br />
<br />
=== What inputs connectors will Channels 1 and 2 accept? === <br />
<br />
Channels 1 and 2 accept two types of input connections: a balanced XLR (mic) connection, and a ¼-inch phone connector unbalanced (line) input for passive instruments such as guitar.<br />
<br />
=== What are the critical frequencies (Q-points) of the R1 remote control? === <br />
<br />
The MID control is centered about 1.2 KHz with a Q of approximately 1. HIGH and LOW responses are shelving. We are reluctant to quote shelving frequencies because there is no clear industry standard definition of a shelf<nowiki>’</nowiki>s "cutoff frequency."<br />
<br />
=== Can I use the system outside? === <br />
<br />
Yes. You can use your system for outdoor gigs. The system has been tested to operate in 0°C to 50°C temperatures and be stored in -30°C to 70°C temperatures. In cases of light rain outside, take precautions to cover the back panel of the power stand. Water must not get into the air inlet slits inside the back panel, on the loudspeaker drivers or inside the {{L1 nl}} cavity on the power stand.<br />
<br />
Unofficial FAQ Extension:<br />
{{#lst:Temperature|conversions}}<br />
<br />
=== There is a buzz in the system. Any suggestions on how to fix it? === <br />
<br />
Noise and buzzing are typical problems with pro audio gear. The new Bose® approach is very much immune to noise because it is a simple, independent system. The typical buzzes and hums associated with ground loops are gone when you use an independent system that is not interconnected electronically to other pieces of equipment. This is not a comprehensive guide to noise troubleshooting, but will offer a suggestion. One of the most important suggestions to alleviate buzz and hum in a system is to plug all interconnected gear into the same electrical circuit. Guitar players or vocalists with effects should plug those units into the same electrical outlet as their power stand is plugged into. This normally fixes all problems. Do not use 3-prong to 2-prong adapters, also known as "cheaters" or "ground lifters." Bypassing a safety grounding mechanism is a serious safety threat.<br />
<br />
=== Why doesn<nowiki>’</nowiki>t Bose Corporation publish full system specifications? === <br />
<br />
Most of the specifications that are used to describe sound systems can be very misleading.<br />
<br />
They pretend that relatively complex physical or perceptual properties can be condensed to a single number (or a small set of numbers) that determines somehow the quality of a product. These numbers then are used to compare or rank different products. In many cases, these numbers only loosely relate to what a user would experience in a real-world application. Furthermore, there are quite a number of variations in the details of how a specific measurement can be carried out. We believe it serves our customers better to describe the product in terms that they can more directly relate to, and to enable and encourage our customers to experience the product directly either through a demonstration or through actual real-world trials they conduct themselves.<br />
<br />
Bose Corporation publishes technical data whenever we think it is helpful. For example, for our products that are used primarily in installed sound systems, detailed technical specifications are available. This data is normally used by professional sound system engineers, who are well-trained to interpret the data correctly and put it into the right context. While some specifications add value in comparing two products that are otherwise very similar, they are mostly meaningless for a product that is fundamentally different, such as the Cylindrical Radiator® loudspeaker and the Bose {{L1 nl}} Model I system.<br />
<br />
=== How prone is the system to feedback? === <br />
<br />
The {{L1 nl}} Model I system is resistant to, but not immune from, feedback. Its performance in this critical dimension has been shown, in the vast majority of cases, to be significantly better than the traditional triple system amplification approach of backline instrument amplifiers, monitor system and PA system.<br />
<br />
=== Can I connect a passive subwoofer to the Bass Module Output? === <br />
<br />
No. We do not recommend that you connect anything except the B1 bass module to this output, as the internal amplifier and B1 bass module(s) are designed to properly equalize the system when connected. However, you may utilize the '''Bass Line Out''' connection to feed a powered subwoofer or additional amplifier.<br />
<br />
== Applications ==<br />
<br />
=== Where can the {{L1 nl}} Model I system be used? === <br />
<br />
The {{L1 nl}} Model I system is suitable for amplified music performances in venues with occupancies up to 500 people. Typically, this translates to maximum listener distances of about 150 feet (45 meters). Thus the system will fill auditoriums, places of worship, gymnasiums, ballrooms, dance clubs, coffeehouses and more – places where the vast majority of live music performances take place. Furthermore, tests have been conducted that show that in larger venues, a musical group can use the new approach on stage and enjoy all the benefits that allow musicians to hear themselves and each other better. Signals from the stage can then be fed to speakers that supply sound to distant seating areas.<br />
<br />
=== What kinds of musical groups can use the new technology? === <br />
<br />
There are no restrictions in this regard. Any instrument, any group size and any genre will benefit from the advantages of hearing themselves better, of being in complete control of their music, of having their audiences hear them better, and of being able to set up and play in a small fraction of the time it takes to set up a conventional system.<br />
<br />
=== You talk about excessive loudness. Are you saying the new system isn<nowiki>’</nowiki>t capable of playing loud? How loud can it play? === <br />
<br />
The new approach can compete with the maximum levels created by most conventional systems. What<nowiki>’</nowiki>s changed is that a band will rarely, if ever, play at the kind of sustained or persistently high sound levels, because the struggle to hear oneself and one<nowiki>’</nowiki>s fellow musicians – the reason to increase the volume in the first place – is gone. With the new approach, therefore, the dynamics are vastly improved, one of the major contributors to musical quality. In testing at Bose, musical groups plagued by the problem of excessive loudness were delighted to find that within a very short time (one or two sessions), their average level had dropped drastically while their peak level remained the same. They expressed an enormous increase in the enjoyment of playing, and audiences expressed their appreciation of music that was exciting but not overwhelmingly loud.<br />
<br />
=== Does every musician in the band need his or her own {{L1 nl}} Model I system? === <br />
<br />
No. In the fullest embodiment of this new approach, each musician in a group has a {{L1 nl}} Model I system. In some situations – a larger ensemble on a small stage, for example – testing showed that two or more musicians could share one {{L1 nl}} Model I system without a significant erosion of the benefits of the concept when the musicians were standing or sitting directly next to each other. Two horn players standing side by side or three support vocalists standing next to each other can use one L1 Model I system, as an example.<br />
<br />
=== Can one musician use an {{L1 nl}} system while the rest of the band plays through a conventional system? === <br />
<br />
Yes. There are two ways that a musician can use the {{L1 nl}} Cylindrical Radiator® loudspeaker onstage with a band using the conventional triple system setup.<br />
<br />
A performer can use the system onstage without connecting to any other house reinforcement equipment, including the main front speakers (sometimes known as "house mains") and stage monitors. However, only some of the benefits of the new approach are enjoyed in this case.<br />
<br />
The musician using the {{L1 nl}} Model II system will hear him or herself better, will be heard better <br />
by the other musicians and will be heard better by the audience. However, the full potential of this new system is not realized because only the performer and not the complete band is equipped and engaged to perform with the benefits of this new amplification approach.<br />
<br />
Performers can also use {{L1 nl}} Model II systems to enhance their sound onstage, and use the available Line Output jacks on the primary channels to send the audio signal(s) to a house PA. In this case, the musician and the band enjoy the benefits from the musician<nowiki>’</nowiki>s sound onstage and only onstage. There are no advantages for the audience. Loss of the benefits of the "cocktail party" effect, lack of eye-ear coordination, the potential for excessive reverberation, and the problems of bulky and complex equipment all exist if the remainder of the band plays through a triple system.<br />
<br />
=== Can DJs use this system? === <br />
<br />
Yes. The system has important advantages over conventional systems. One problem with portable<br />
<br />
PA systems is the use of stand-mounted speakers, which are very loud close to the speaker and not loud enough away from the speaker. The {{L1 nl}} Cylindrical Radiator® loudspeaker is unusual in that you can adjust for the desired level on the dance floor and in the audience, and then walk literally right next to the speaker without it getting excessively loud. This translates into much greater comfort for the guests.<br />
<br />
The system also has a sleek, elegant profile that fits nicely into event décors and minimizes sight-line issues.<br />
<br />
=== Can {{L1 nl}} systems be used as a traditional PA system? === <br />
<br />
Yes. {{L1 nl}} Model I systems can be used to replace PA speakers. Their unique radiation properties help them deliver more even sound coverage and a larger stereo field – a benefit that has been confirmed in listening tests. The benefits of compactness for transportation and rapid assembly will also be enjoyed.<br />
<br />
=== Can musicians really mix themselves? === <br />
<br />
Yes, when they are in complete control of their sound. Musicians know how to play together acoustically and have done so countless times, regardless of whether they also play with amplification. All musicians know how to alter their playing in order to create a balance when playing with others. In extensive testing at Bose, it was found that this skill is quickly revived when using the {{L1 nl}} system.<br />
<br />
=== Does this approach work for electric guitar? Aren<nowiki>’</nowiki>t guitarists particular about their guitar amplifiers? === <br />
<br />
Yes. For most electric guitarists, the guitar amplifier is considered a part of their instrument, as<br />
<br />
inseparable from the sound of their instrument as is the wood and body shape of an acoustic<br />
<br />
guitar. For example, the distortion created by the electronic tubes in some guitar amplifiers<br />
<br />
produces tones essential to many guitarists<nowiki>’</nowiki> sound. Even the speaker transducers and speaker cabinets used in guitar amplifiers produce unique tone essential to some players<nowiki>’</nowiki> sound.<br />
<br />
=== How can these elements of the electric guitar<nowiki>’</nowiki>s tone be included in the {{L1 nl}} system approach? === <br />
<br />
There are at least three ways this can be done, and each has been extensively tested by<br />
<br />
guitarists participating in the Bose® research that led to the new approach. The advantage gained<br />
<br />
in these approaches constitutes what is arguably the most important gain in electrical guitar<br />
<br />
sound since the invention of the guitar amplifier itself. The reason is that the Cylindrical<br />
<br />
Radiator® loudspeaker overcomes the problem of uneven radiation of sound to the stage and<br />
<br />
audience from traditional guitar amplifiers. This is of particular interest for the electric<br />
<br />
guitar because the radiation pattern of typical guitar amplifiers is so harshly directional as to be<br />
<br />
painful to listeners on-axis, and dull and muddy off-axis. Before, guitarists could create the<br />
<br />
desired "sweet spot" sound in one location (theirs), while all others were blasted on-axis or<br />
<br />
couldn<nowiki>’</nowiki>t hear the detail well off-axis.<br />
<br />
1) A number of companies have in the past 10 years produced electronic devices that model<br />
<br />
the tone produced by tubes, guitar transducers and guitar amplifier speaker cabinets. These<br />
<br />
modeling amps initially helped to solve the problem of recording electric guitar and have become increasingly popular on stage. The electric guitarist simply plugs into one of these devices and the output of the device is then plugged into the {{L1 nl}} Model II system. This is the most convenient and elegant way to use electric guitar with the L1 system.<br />
<br />
2) One of a number of tube-based or solid-state guitar preamplifiers can be used. The output of these preamplifiers is plugged directly into the power stand.<br />
<br />
3) The third way is for purists who are not satisfied that the modeling amps (first solution above)<br />
<br />
capture all of the nuances of a traditional guitar amplifier. These guitarists can use a tube<br />
<br />
amplifier with a microphone in front of the amplifier. Exceptional results have been obtained with<br />
<br />
the use of one of a growing number of low-wattage tube amplifiers. This class of guitar amplifier is<br />
<br />
becoming popular with players who want the tone of a tube amplifier but do not want to produce<br />
<br />
extremely high sound levels in order to get that tone.<br />
<br />
=== How does the output of an {{L1 nl}} Model I system compare to a loud stack of guitar amplifiers and cabinets? === <br />
<br />
The full stack is considered a standard by many guitarists, both in terms of tone and output.<br />
<br />
An {{L1 nl}} Model I system can compete effectively with the output of a full stack. However, there are other benefits, such as the radiation pattern of the L1 Model I system, that distinguish it from the full stack<nowiki>’</nowiki>s acute directional beam. Moreover, the Model I system can be used to amplify other instruments at the same time. The full stack is for one thing only: electric guitar.<br />
<br />
=== Can you create distortion for guitars with the {{L1 nl}} system? === <br />
<br />
No. Distortion must be produced first and then fed into the power stand as a clean, non-clipping signal. To achieve distortion, the guitarist can use a few methods:<br />
<br />
- Inline devices: One popular method would be to use any of the effects pedals on the market or use a DSP-based amplifier modeler, such as the Line 6 "Pod," which models the tone produced by amplifier tubes, guitar transducers and guitar amplifier speaker cabinets.<br />
<br />
- Miking a guitar amplifier: Another method would be to use a guitar amplifier and mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest possible level at which the correct tone is attainable but does not diminish the benefits of the {{L1 nl}} Model I system. Louder amplifiers can be located and miked offstage. Miking small, low-watt amplifiers is a better technique for this method.<br />
<br />
- Use a loading device. Some electric guitarists may prefer to use their amplifier<nowiki>’</nowiki>s output as an input signal into the power stand. Before doing this, they must use a load device such as a "Plate Soak" or a<br />
<br />
"Hot Plate" to give a line-level output suitable for the input stage of the power stand.<br />
<br />
- Use the "line output" of a guitar amplifier. Some amplifiers have this option and may be suitable for some guitarists. The only suggestion here is to turn the volume of the amplifier down so only the {{L1 nl}} Model I system is heard.<br />
<br />
<br>Refer to the Bose® website and Musicians Community Forum at http://www.Bose.com/musicians to learn how to interface additional instruments with the system.<br />
<br />
=== Can acoustic instruments be amplified with the {{L1 nl}} Model I system? === <br />
<br />
Yes. If the acoustic instrument has a pickup system, then you may connect directly into the system. In cases where pickups are not present, a microphone may be used. The Model I power stand is equipped with 24 v phantom power capability for Channels 1 and 2 to power condenser microphones.<br />
<br />
=== How many B1 bass modules can I stack up on stage or when transporting? === <br />
<br />
Up to four B1 bass modules may be stacked in a column using the integrated alignment tabs on the sides of the enclosures.<br />
<br />
=== Where can I collaborate with Bose staff and existing owners to learn more on how the {{L1 nl}} Model I system can work for my specific application? === <br />
<br />

<br />
== The {{L1 nl}} Product Family ==<br />
<br />
=== When was the {{L1 nl}} Model I system first available for consumers to purchase? === <br />
<br />
On October 15, 2003, Bose Corporation began selling the {{L1 nl}} Model I family of products through our internal CFDT sales division, and [http://www.bose.com/ www.Bose.com] (in the U.S., Puerto Rico, Canada or U.S. Virgin Islands only). Guitar Center® and Musicians Friend® began selling these products on November 1, 2003, in stores nationwide.<br />
<br />
=== Do the new products compete with Bose<nowiki>’</nowiki>s other portable professional systems? === <br />
<br />
There are some situations where in the past we would have recommended a Bose® solution comprised of our other portable products, where today we would recommend the {{L1 nl}} Model II system instead. Live music performance is the most obvious application where we would do so. There remain a number of applications where our other portable products are an excellent choice.<br />
<br />
=== Where can you hear and try the {{L1 nl}} Model I system? === <br />
<br />
Order it and try it for 45 days directly from Bose Corporation. We encourage customers to experience the {{L1 nl}} in their own environment with their specific gear. That is why we offer the ability for you to purchase and use the system in your specific application for up to 45 days, and if for any reason you are not satisfied you may return it for a refund. This offer is exclusive to Bose® direct sales channels.<br />
<br />
Additionally, you easily can try out the product at Guitar Center® stores nationwide. Other methods of demonstration are available in North America. For more details, visit [http://www.bose.com/musicians www.Bose.com/musicians].<br />
<br />
=== How does the cost of the {{L1 nl}} Model I compare to traditional PA equipment? === <br />
<br />
Because of the enormous reduction in complexity, the new system compares favorably with the cost of a high-quality conventional amplification system for a four piece band. However, the enormous reduction in transportation and set up costs mean that the new system is much less expensive to own and operate. Superiority is achieved when this cost advantage is combined with what we feel is a quantum improvement in sound quality.<br />

The limited warranty on all electronic components in the U.S. is one year (the power stand and PackLite® amplifier) and five years on loudspeakers (the {{L1 nl}} Model I system and B1 bass module). For limited warranty information in other parts of the world, please visit [https://www.bhtu.com/Local Settings/Application Data/Microsoft/Word/www.bose.com/musicians www.Bose.com/musicians] for more information.<br />
<br />
=== Can I use this 120-volt system in another country? === <br />
<br />
No. The unit does not have a universal power supply. Use the 120V version only in 120V countries. Use the 240V version in countries with 220, 230 or 240V systems at 50 Hz. We do not have a 100V system.<br />
<br />
=== I need a longer NL4 cable for my B1 bass module. What are my options? === <br />
<br />
It is generally good practice to locate the B1 bass modules near the Cylindrical Radiator® loudspeaker. If you require more length, ensure that it is a 4-conductor NL4 speaker cable. One vendor that we have used is [http://www.audiopile.net/ www.audiopile.net].<br />

=== Why does an {{L1}} Model II power stand contain only a single analog input? ===<br />
The {{L1}} Model II system provides a single analog input suitable for many applications and compatible with standard mixers, DJ mixers, laptops and other devices. This enables the layout of the power stand to be less cluttered, with no unnecessary connectors. The end result is a clean, compact and efficient design.<br></p> <p> For musicians who need more inputs, our multichannel T1 ToneMatch® audio engine is designed to work with an {{L1}} Model II system via a simple digital connection. It offers three mic/line inputs, two line inputs (L/R), our largest library of ToneMatch presets, proprietary zEQ and a complete suite of studio-class effects and processing.<br />
<br />
=== What's the proper method for setting the gain on a Model II power stand when connected to an analog source? ===<br />
While playing your instrument or audio source as loudly as you would in performance, adjust the trim level on the power stand until you see the LED go from yellow to red. Then back the trim level off until the signal LED is predominantly yellow with brief peaks into red.<br />
<br />
===What's the proper method for setting the gain on a Model II power stand when connected to a T1 ToneMatch audio engine? ===<br />
Set the output volume of your source to normal operating volume. Make sure the master volume and channel volume on the ToneMatch audio engine are set to 0. While playing your instrument or audio source as loudly as you would in performance, turn the appropriate channel's trim control clockwise until the signal/clip indicator glows green or yellow. If the indicator flashes red or glows steady red, turn the trim control counterclockwise to decrease the level.<br />

== The Technology ==<br />
<br />
=== What is the L1™ Model II system? ===<br />
<br />
The L1™ Model II system represents a new approach to amplification. This approach was designed to address the root cause of complaints by musicians and audience members regarding the quality of live amplified musical performances.<br />
<br />
=== How does this approach work? ===<br />
<br />
In the new approach mixer, PA speakers, monitors and backline amplifiers (e.g. guitar amps) are replaced by special Cylindrical Radiator® loudspeakers, which are located behind the musicians. These speakers have the unique ability to radiate sound evenly across the stage and into the audience with very little change in sound level.<br />
<br />
The approach is naturalistic in that it mimics an acoustic instrument performance: Each player has control over his or her individual sound, and the sound comes from the multiple directions that correspond to the musician<nowiki>’</nowiki>s positions on stage – a property of acoustic music known to enhance our ability to hear and appreciate individual instruments and voices in ensemble passages. The new approach has many integrated features that allow the user to set up the system in just minutes.<br />
<br />
=== Is this technology better-suited for seasoned musicians who already have tons of gear, or for musicians that are just getting started and need a simple solution? ===<br />
<br />
The system is equally valuable for the seasoned musician and the beginner. Experienced performers immediately will recognize that they can hear better and therefore play better, and they instantly appreciate the easy setup. Musicians who are starting will enjoy playing more because they<nowiki>’</nowiki>ll spend more time playing and less time hassling with equipment. They will develop as better players because they can hear themselves and each other. All will benefit from the knowledge that the sound they produce on stage is what is radiated to the audience. Never again will they hear and think one thing only to find out the audience heard something completely different when they asked "How did we sound?" after the performance.<br />
<br />
=== What are some of the details of the electronics in the L1™ Model II power stand? ===<br />
<br />
Powerful amplification is enclosed in the Model II power stand – enough to drive the L1™ Model II system and up to two B1 bass modules to output levels required by bands in venues up to about 500 people.<br />
<br />
=== Why does the Model II power stand contain only a single analog input? ===<br />
<br />
Based on customer feedback, Bose provides a single analog input, which is suitable for many applications and is compatible with outputs from standard mixing consoles, DJ mixers, laptop computers and many other devices. This enables the layout of the power stand to be less cluttered with connectors that ultimately may not be used for many applications. The end result is a clean and compact design.<br />
<br />
Musicians who require more inputs can purchase the T1 ToneMatch™ audio engine, which is specifically designed to work with the L1™ Model II system. The T1 is a powerful multichannel audio device designed for musicians to use with the Model II system. It includes our largest library of ToneMatch™ presets, proprietary zEQ, a complete suite of studio-class effects and processing, and five channel inputs.<br />
<br />
=== Are there similarities between the L1™ Model II system and line arrays currently in use? ===<br />
<br />
Line arrays have been used for large concert performances as the PA component of a traditional triple amplification system. Unlike these large-venue systems, the L1™ Model II system is designed as a portable implementation of a line or pole-shaped source. It is designed to be positioned behind each musician, providing accurate coverage for musicians and audiences.<br />
<br />
=== In nightclubs, you normally see very large loudspeakers for bass. How do your smaller bass enclosures compare? What makes them so special? ===<br />
<br />
Bose has a number of propriety technologies for bass and has a long history of developing systems that produce high output in the bass range from smaller enclosures. The B1 bass module is no exception. The fact that it is used in an integrated system (with amplification and signal processing) means that performance can be enhanced in ways that a conventional component-based solution can<nowiki>’</nowiki>t. Large signal performance, for example, can be greatly improved with the use of a dedicated digital signal processor, which is built into the T1 ToneMatch™ audio engine.<br />
<br />
At the same time, the B1 bass module has been made modular, so that higher bass output can be created for instruments and styles that require it. An upright bass in a jazz trio might use only one bass module. On the other extreme, the electric bass in a 10-piece funk band might use four.<br />
<br />
== Functionality ==<br />
<br />
=== Is this really a "plug and play" solution? How long does it take to set up? ===<br />
<br />
The L1™ Model II system is designed to disassemble into easy-to-carry pieces. Everything can be carried by hand without the need for special equipment. Moreover, the products are designed to assemble in just minutes, and because the approach requires no mixing, the complex task of wiring each instrument to the mixer and then from the mixer to the amplifiers and speakers is eliminated. The musicians simply plug in, and they<nowiki>’</nowiki>re ready to play.<br />
<br />
=== Are sound operators required in the new approach? ===<br />
<br />
No. Just as acoustic-instrument ensembles (such as a string quartet) are able to balance their own sound, so too can a group playing amplified music using the new approach. The reason is that when musicians are in total control, and know that the sound they are creating on stage is what is radiated outward to the audience, they are best-suited to creating the required balance of voices and instruments.<br />
<br />
=== What happens if a musician is blocking the view of the L1™ Model II system? Doesn<nowiki>’</nowiki>t that block the sound? ===<br />
<br />
Sound diffracts (bends) around objects. So long as the musician is not standing literally against the L1™ Model II system, the sound diffracts around the musician or other objects such as a keyboard or other musical instrument.<br />
<br />
Connectivity:<br />
<br />
=== What is the proper method for setting the gain on the L1™ Model II power stand when connected to an analog source? ===<br />
<br />
Play source material at the loudest volume that will be present in the performance and adjust the trim level until you achieve the desired volume. Refer to the signal clip LED on the power stand while adjusting the trim level until you see the LED go from yellow to red in color. Back the trim level off until the signal LED is predominantly yellow with brief peaks into the red.<br />
<br />
=== What is the proper method for setting the gain on the L1™ Model II power stand when connected to a T1 ToneMatch™ audio engine? ===<br />
<br />
Adjust output volume of source to normal operating volume. Make sure that the Master volume and the channel volume on the T1 is set to 0. While playing your instrument/audio sources as loudly as you would during a performance, turn the Trim control on applicable channel of the T1 clockwise until the signal/clip indicator glows green or yellow. If the indicator flashes red or glows steady red, turn the trim control counter-clockwise to decrease the level.<br />
<br />
=== Can I use the bass-line-out on the L1™ Model II power stand to connect to a bass amplifier and cabinet? ===<br />
<br />
The bass-line-out connector provides a flat 40-Hz to 180-Hz bandpass signal when no B1 bass modules are used with the power stand. We recommend unplugging the B1 bass modules to ensure correct EQ compensation of the Bass Line OUT jack, and phase consistency.<br />
<br />
=== Do the mic inputs of the T1 ToneMatch™ audio engine have phantom power? ===<br />
<br />
Phantom power <nowiki>+</nowiki>48v can be applied to Channels 1-3.<br />
<br />
=== How many B1 bass modules can you connect? ===<br />
<br />
One power stand can power up to two B1 bass modules.<br />
<br />
=== Can this product be used in other countries? ===<br />
<br />
There are two voltage versions of the power stand and the A1 PackLite® amplifier. 120V versions are available in the U.S., Canada and some Latin American countries. The 230V versions are available in Europe and Australia.<br />
<br />
Please visit http://www.Bose.com/musicians for up-to-date information about product availability.<br />
<br />
=== How do I know which half of the Cylindrical Radiator® to insert into the power stand first? ===<br />
<br />
The upper and lower halves of the L1™ Model II system are not identical. The bottom half is easily identifiable because it has a large end cap, which gets inserted first into the power stand. The upper half contains the Bose® logo and uses a tongue-and-groove mechanism to ensure a solid mechanical and electrical connection to the lower half. Both halves are clearly labeled on the back, indicating proper insertion.<br />
<br />
=== Can you use 2-wire Speakon® cables for the B1 bass modules? ===<br />
<br />
No. Only 4-wire Speakon® cables should be used with the power stand. The additional two wires (<nowiki>+</nowiki>2 and -2) in the connector are used for sensing purposes. Upon connection, the power stand is able to sense and adjust (EQ and level) for 0, 1 or 2 B1 bass modules connected to the bass-module-out Speakon® connector.<br />
<br />
=== How can I tell if I<nowiki>’</nowiki>m using the correct Speakon® cable? ===<br />
<br />
If you plug in a 4-wire Speakon® cable to the bass-module-out connector with music playing through, you will clearly hear the L1™ Model II system mute for a moment. If you are using an incorrect cable, such as a 2-wire Speakon® cable, the momentary muting will not occur.<br />
<br />
=== Can the system be used with just one half of a L1™ Model II system in instances where the ceiling may not be tall enough for assembly of the full loudspeaker? ===<br />
<br />
Using only one half of the L1™ Model II system will significantly impact the performance. The EQ would be incorrect and your ears still need to be at the same height as some part of the loudspeaker, which is difficult at 3.5 feet tall. While there should not be any damage to the system by using it like this, it is not recommended.<br />
<br />
=== Can I use the system outside? ===<br />
<section begin=temperature /><br />
Yes. You may use your system for outdoor gigs, provided that it is protected from extreme elements. The system has been tested to operate in 0°C to 50°C temperatures and be stored in -30°C to 70°C temperatures. In cases of light rain outside, take precautions to cover the back panel of the power stand. Water must not get into the air inlet slits inside the back panel, on the loudspeaker drivers or inside the L1™ cavity on the power stand.<br />

<br />
<br />
=== Why doesn<nowiki>’</nowiki>t Bose Corporation publish full system specifications? ===<br />
<br />
Most of the specifications that are used to describe sound systems can be very misleading.<br />
<br />
They pretend that relatively complex physical or perceptual properties can be condensed to a single number (or a small set of numbers) that determines somehow the quality of a product. These numbers then are used to compare or rank different products. In many cases, these numbers only loosely relate to what a user would experience in a real-world application. Furthermore, there are quite a number of variations in the details of how a specific measurement can be carried out. We believe it serves our customers better to describe the product in terms that they can more directly relate to, and to enable and encourage our customers to experience the product directly either through a demonstration or through actual real-world trials they conduct themselves.<br />
<br />
Bose Corporation publishes technical data whenever we think it is helpful. For example, for our products that are used primarily in installed sound systems, detailed technical specifications are available. This data is normally used by professional sound system engineers, who are well-trained to interpret the data correctly and put it into the right context. While some specifications add value in comparing two products that are otherwise very similar, they are mostly meaningless for a product that is fundamentally different or new, such as the L1™ Model II system.<br />
<br />
=== How prone is the system to feedback? ===<br />
<br />
The L1™ Model II system is resistant to, but not immune from, feedback. Its performance in this critical dimension has been shown, in the vast majority of cases, to be significantly better than the traditional triple system amplification approach of backline instrument amplifiers, monitor system and PA system.<br />
<br />
=== Can I connect a passive sub woofer to the Bass Module Output? ===<br />
<br />
No. We do not recommend that you connect anything except the B1 bass module to this output, as the internal amplifier and B1 bass modules are designed to properly equalize the system when connected. Use the '''Bass Line Out''' connection to feed a powered subwoofer or additional amplifier.<br />
<br />
== Applications ==<br />
<br />
=== Where can the L1™ Model II system be used? ===<br />
<br />
The L1™ Model II system is suitable for amplified music performances in venues with occupancies up to 500 people. Typically, this translates to maximum listener distances of about 150 feet (45 meters). Thus the system will fill auditoriums, places of worship, gymnasiums, ballrooms, dance clubs, coffeehouses and more – places where the vast majority of live music performances take place. In larger venues, a musical group can use the new approach on stage and enjoy all the benefits that allow musicians to hear themselves and each other better. Signals from the stage can be fed to speakers that supply sound to distant seating areas.<br />
<br />
=== What kinds of musical groups can use the new technology? ===<br />
<br />
There are no restrictions in this regard. Any instrument, any group size and any genre will benefit from the advantages of hearing themselves better, of being in complete control of their music, of having their audiences hear them better, and of being able to set up and play in a small fraction of the time it takes to set up a conventional system.<br />
<br />
=== You talk about excessive loudness. Are you saying the new system isn<nowiki>’</nowiki>t capable of playing loud? How loud can it play? ===<br />
<br />
The new approach can compete with the maximum levels created by most conventional systems. What<nowiki>’</nowiki>s changed is that a band will rarely, if ever, play at the kind of sustained or persistently high sound levels, because the struggle to hear oneself and one<nowiki>’</nowiki>s fellow musicians – the reason to increase the volume in the first place – is gone. With the new approach, therefore, the dynamics are vastly improved, one of the major contributors to musical quality. In testing at Bose, musical groups plagued by the problem of excessive loudness were delighted to find that within a very short time (one or two sessions), their average level had dropped drastically while their peak level remained the same. They expressed an enormous increase in the enjoyment of playing, and audiences expressed their appreciation of music that was exciting but not overwhelmingly loud.<br />
<br />
=== Does every musician in the band need his or her own L1™ Model II system? ===<br />
<br />
No. In the fullest embodiment of this new approach, each musician in a group has a L1™ Model II system. In some situations – a larger ensemble on a small stage, for example – testing showed that two or more musicians could share one L1™ Model II system without a significant erosion of the benefits of the concept when the musicians were standing or sitting directly next to each other. Two horn players standing side by side or three support vocalists standing next to each other can use one L1 Model II system, as an example.<br />
<br />
=== Can one musician use an L1™ system while the rest of the band plays through a conventional system? ===<br />
<br />
Yes. There are two ways that the musician can use the L1™ Cylindrical Radiator® loudspeaker onstage with a band using the conventional triple system setup.<br />
<br />
A performer can use the system onstage without connecting to any other house reinforcement equipment, including the main front speakers (sometimes known as "house mains") and stage monitors. However, only some of the benefits of the new approach are enjoyed in this case. The musician using the L1™ Model II system will hear him or herself better, will be heard better by the other musicians and will be heard better by the audience. However, the full potential of this new system is not realized because only the performer and not the complete band is equipped and engaged to perform with the benefits of this new amplification approach.<br />
<br />
Performers can also use L1™ Model II systems to enhance their sound onstage, and use the available Line Output jacks on the primary channels to send the audio signal(s) to a house PA. In this case, the musician and the band enjoy the benefits from the musicians<nowiki>’</nowiki> sound onstage and only onstage. There are no advantages for the audience. Loss of the benefits of the "cocktail party" effect, lack of eye-ear coordination, the potential for excessive reverberation, and the problems of bulky and complex equipment all exist if the remainder of the band plays through a triple system.<br />
<br />
=== Can DJs use this system? ===<br />
<br />
Yes. The system has important advantages over conventional systems. One problem with portable<br />
<br />
PA systems is the use of stand-mounted speakers, which are very loud close to the speaker and not loud enough away from the speaker. The L1™ Cylindrical Radiator® loudspeaker is unusual in that you can adjust for the desired level on the dance floor and in the audience, and then walk literally right next to the speaker without it getting excessively loud. This translates into much greater comfort for the guests.<br />
<br />
The system also has a sleek, elegant profile that fits nicely into event décors and minimizes sight-line issues.<br />
<br />
=== Can L1™ systems be used as a traditional PA system? ===<br />
<br />
Yes. L1™ Model II systems can be used to replace PA speakers. Their unique radiation properties help them deliver more even sound coverage and a larger stereo field – a benefit that has been confirmed in listening tests. The benefits of compactness for transportation and rapid assembly also will be enjoyed.<br />
<br />
=== Can musicians really mix themselves? ===<br />
<br />
Yes, when they are in complete control of their sound. Musicians know how to play together acoustically and have done so countless times, regardless of whether they also play with amplification. All musicians know how to alter their playing in order to create a balance when playing with others. In extensive testing at Bose, it was found that this skill is quickly revived when using the L1™ system.<br />
<br />
=== Does the new approach work for electric guitar? Aren<nowiki>’</nowiki>t guitarists particular about their guitar amplifiers? ===<br />
<br />
Yes. For most electric guitarists, the guitar amplifier is considered a part of their instrument, as inseparable from the sound of their instrument as is the wood and body shape of an acoustic guitar. For example, the distortion<br />
<br />
created by the electronic tubes in some guitar amplifiers produces tones essential to many guitarists<nowiki>’</nowiki> sound. Even the speaker transducers and speaker cabinets used in guitar amplifiers produce unique tone essential to some players<nowiki>’</nowiki> sound.<br />
<br />
=== How can these elements of the electric guitar<nowiki>’</nowiki>s tone be included in the L1™ system approach? ===<br />
<br />
There are at least three ways this can be done, and each has been extensively tested by guitarists participating in the Bose® research that led to the new approach. The advantage gained in these approaches constitutes what is arguably the most important gain in electrical guitar sound since the invention of the guitar amplifier itself. The reason is that the Cylindrical Radiator® loudspeaker overcomes the problem of uneven radiation of sound to the stage and audience from traditional guitar amplifiers. This is of particular interest for the electric guitar because the radiation pattern of typical guitar amplifiers is so harshly directional as to be painful to listeners on-axis, and dull and muddy off-axis. Before, guitarists could create the desired "sweet spot" sound in one location (theirs), while all others were blasted on-axis or couldn<nowiki>’</nowiki>t hear the detail well off-axis.<br />
<br />
1) A number of companies have in the past 10 years produced electronic devices that model the tone produced by tubes, guitar transducers and guitar amplifier speaker cabinets. These modeling amps initially helped to solve the problem of recording electric guitar and have become increasingly popular on stage. The electric guitarist simply plugs into one of these devices and the output of the device is then plugged into the L1™ Model II system. This is the most convenient and elegant way to use electric guitar with the L1 system.<br />
<br />
2) One of a number of tube-based or solid-state guitar preamplifiers can be used. The output of these preamplifiers is plugged directly into the power stand.<br />
<br />
3) The third way is for purists who are not satisfied that the modeling amps (first solution above) capture all of the nuances of a traditional guitar amplifier. These guitarists can use a tube amplifier with a microphone in front of the amplifier. Exceptional results have been obtained with the use of one of a growing number of low-wattage tube amplifiers. This class of guitar amplifier is becoming popular with players who want the tone of a tube amplifier but do not want to produce extremely high sound levels in order to get that tone.<br />
<br />
=== How does the output of an L1™ Model II system compare to a loud stack of guitar amplifiers and cabinets? ===<br />
<br />
The full stack is considered a standard by many guitarists, both in terms of tone and output.<br />
<br />
An L1™ Model II system can compete effectively with the output of a full stack. However, there are other benefits, such as the radiation pattern of the L1 Model II system, that distinguish it from the full stack<nowiki>’</nowiki>s acute directional beam. Moreover, the Model II system can be used to amplify other instruments at the same time. The full stack is for one thing only: electric guitar.<br />
<br />
=== Can you create distortion for guitars using the L1™ system? ===<br />
<br />
No. Distortion must be produced first and then fed into the power stand as a clean, non-clipping signal. To achieve distortion, the guitarist can use a few methods:<br />
<br />
- Inline devices: One popular method would be to use any of the effects pedals on the market or use a DSP-based amplifier modeler, such as the Line 6 "Pod," which models the tone produced by amplifier tubes, guitar transducers and guitar amplifier speaker cabinets.<br />
<br />
- Miking a guitar amplifier: Another method would be to use a guitar amplifier and mic the speaker as closely as possible. The trick here is to run the amplifier at the lowest possible level at which the correct tone is attainable but does not diminish the benefits of the L1™ Model II system. Louder amplifiers can be located and miked offstage. Miking small, low-watt amplifiers is a better technique for this method.<br />
<br />
- Use a loading device. Some electric guitarists may prefer to use their amplifier<nowiki>’</nowiki>s output as an input signal into the power stand. Before doing this, they must use a load device such as a "Plate Soak" or a "Hot Plate" to give a line-level output suitable for the input stage of the power stand.<br />
<br />
- Use the "line output" of a guitar amplifier. Some amplifiers have this option and may be suitable for some guitarists. The only suggestion here is to turn the volume of the amplifier down so only the L1™ Model II system is heard.<br />
<br />
Refer to the Bose® website and Musicians Community Forum at [http://www.bose.com/musicians http://www.Bose.com/musicians] to learn how to interface additional instruments with the system.<br />
<br />
=== Can acoustic instruments be amplified with the L1™ Model II system? ===<br />
<br />
Yes. When a T1 is not connected, an acoustic instrument equipped with a pickup system may connect directly into the Model II power stand. In cases where pickups are not present, a microphone may be used. When a T1 is not being used, you may connect directly into the Model II system<nowiki>’</nowiki>s analog input. However, in this instance, a microphone cable must be used in conjunction with a direct box or a transformer to adapt to the power stands ¼ "analog input connector.<br />
<br />
=== How many B1 bass modules can I stack up on stage or when transporting? ===<br />
<br />
Up to four B1 bass modules may be stacked in a column using the integrated alignment tabs on the sides of the enclosures.<br />
<br />
== General (Product) ==<br />
<br />
=== I already own a L1™ Model I or Model II system. Can I purchase the T1 separately and use it with the system? ===<br />
<br />
Yes. The T1 is available for purchase separately and may be used with either an L1™ Model I or Model II system. When used with a Model II system, the audio is connected digitally via the ToneMatch™ ports. When used with a Model I, a separate power supply is required to power the T1 and the audio is analog. When using with a Model I, simply connect the T1<nowiki>’</nowiki>s Master Output jack to the analog input of Channel 3 or 4 on the Model I power stand. The T1 power supply is available through Bose or authorized dealers of the L1 family of products.<br />

== The L1™ Model II product family ==<br />
<br />
=== When was the L1™ Model II system first available for consumers to purchase? ===<br />
<br />
On March 28, 2007, Bose Corporation introduced the L1™ Model II system. It will be available for sale May 1, 2007, through our internal sales groups and participating authorized dealers.<br />
<br />
=== Do the new products compete with Bose<nowiki>’</nowiki>s other portable professional systems? ===<br />
<br />
Yes. There are some situations where in the past we would have recommended a Bose® solution comprised of our other portable products, where today we would recommend the L1™ Model II system instead. Live music performance is the most obvious application where we would do so. There remain a number of applications where our other portable products are an excellent choice.<br />
<br />
=== Where can you hear and try the L1™ Model II system? ===<br />
<br />
Order it and try it for 45 days directly from Bose Corporation. We encourage customers to experience the L1™ in their own environment with their specific gear. That is why we offer the ability for you to purchase and use the<br />
<br />

Additionally, you can easily try out the product at Guitar Center® stores nationwide. Other methods of demonstration are available in North America. For more details, visit [http://www.bose.com/musicians www.Bose.com/musicians].<br />
<br />
=== How does the cost of the L1™ Model II compare to traditional PA equipment? ===<br />
<br />
Because of the enormous reduction in complexity, the new system compares favorably with the cost of a high-quality conventional amplification system for a four piece band. However the enormous reduction in transportation and set up costs mean that the new system is much less expensive to own and operate. Superiority is achieved when this cost advantage is combined with what we feel is a quantum improvement in sound quality.<br />

=== What are the available accessories for the L1™ family of products? ===<br />
<br />
=== B1 bass module ===<br />
<br />
This compact, powerful bass enclosure is designed to be used with L1™ systems helping to deliver the depth and impact of such instruments as bass guitar, drums and low voices. Low-pitched wind or stringed instruments, guitars and keyboards also can benefit from the additional low-end output that the B1 provides. Includes professional padded gig bag, and one cable to connect the B1 bass module to the power stand and slip cover.<br />
<br />
===Standard B1 carrying cover===<br />
<br />
A standard carrying cover for the B1 bass module. Cover is a direct replacement for the cover included with a new L1™ Model II system package.<br />
<br />
===B1 cable 5.5ft (1.7m)===<br />
<br />
Heavy-duty 4-pin cable connects B1 bass modules to L1™ Model II or II power stands. Longer B1 cables may be obtained from [https://www.bhtu.com/Local Settings/Application Data/Microsoft/Word/www.audiopile.net www.audiopile.net].<br />
<br />

<br />
===Heavy-duty power stand/L1™/duffle carrying bag set===<br />
<br />
Durable and form-fitted, the heavy-duty gig bag set will help protect the L1™ loudspeaker and power stand components during transport. Telescoping travel handle and roller wheels makes for a very easy transport of the power stand. The L1™ bag, lined with extra padding, comes with a shoulder strap. A rugged duffle bag contains convenient pockets and can hold the R1 remote control with plenty of room for cables and accessories.<br />
<br />
===Standard power stand/L1™ carrying bag set===<br />
<br />
Standard carrying bags for the power stand and L1™ loudspeaker. Set of three bags is a direct replacement for the set included with a new L1™ Model II or II system package.<br />
<br />
===L1™ Model II power stand cord (120 volt only)===<br />
<br />
Designed to connect a 120 volt power stand to an AC outlet.<br />
<br />
For product codes and part numbers, please see Appendix A.<br />
<br />
== Support ==<br />
<br />
=== Where can I collaborate with Bose® staff and existing owners to learn more on how the L1™ Model II system can work for my specific application? ===<br />
<br />
We host a public forum that allows our helpful user community to share their experiences and collaborate in real time on topics that are important to them. You will find extensive application specific documentation and helpful hints. The forum is fully searchable and can be accessed at [http://bose.infopop.cc/6/ubb.x http://Bose.infopop.cc/6/ubb.x].<br />
<br />
You also may contact our product support team and speak with our knowledgeable staff of musicians. They may be reached at 877-335-2673.<br />
<br />
=== What is the limited warranty? ===<br />
<br />
The limited warranty on electronic components in the U.S. is one year (the power stand and PackLite® amplifier) and five years on loudspeakers (both the L1™ Model II system and B1 bass module). For limited warranty information in other parts of the world, please visit [https://www.bhtu.com/Local Settings/Application Data/Microsoft/Word/www.bose.com/musicians www.Bose.com/musicians] for more information.<br />
<br />
=== There is a buzz in the system. Any suggestions on how to fix it? ===<br />
<br />
Noise and buzzing is a typical problem with pro audio gear. The new Bose® approach is very much immune to noise because it is a simple, independent system. The typical buzzes and hums associated with ground loops are gone when you use an independent system that is not interconnected electronically to other pieces of equipment. This is not a comprehensive guide to noise troubleshooting, but will offer a suggestion. One of the most important suggestions to alleviate buzz and hum in a system is to plug all interconnected gear into the same electrical circuit. Guitar players or vocalists with effects should plug those units into the same electrical outlet as their power stand is plugged into. This normally fixes all problems.<br />
<br />
=== Can I use this 120-volt system in another country? ===<br />
<br />
The unit does not have a universal power supply; use the 120V version only in 120V countries. Use the 240V version in countries with 220,230 or 240V systems at 50 Hz. We do not have a 100V system.<br />
<br />
=== I need a longer NL4 cable for my B1 bass module. What are my options? ===<br />
<br />
It is generally good practice to locate the B1 bass modules near the L1. If you require more length, ensure that it is a 4-conductor NL4 speaker cable. One vendor that we have used is [http://www.audiopile.net/ www.audiopile.net].<br />
<br />
=== Are there any user-replaceable parts? ===<br />
<br />
Yes. Certain user-replaceable parts are available for the product family. U.S. customers can contact our support department at 877-335-2673 for details.<br />
<br />
=== Are the products repairable? To what extent? ===<br />
<br />
Yes. The products are repairable. The power stand is currently repairable at the board level. Drivers, end caps, and grills can be replaced on the L1™ and B1 units.<br />
<br />
=== What are the replacement costs? ===<br />
<br />
U.S. customers may call 877-335-2673 or e-mail [mailto:support@Bose.com support@Bose.com] for further details.<br />
