| === What exactly are ToneMatch® presets and what are the benefits of using them? ===
| | {{:L1® Model I / FAQ}} |
| Skilled studio engineers listened to the sound of specific instruments and microphones being played through an {{L1}} 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.

| === What is the proper method for setting gain on an {{L1}} Model I power stand? ===
| |
| 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:
| |
| | |
| <ul>
| |
| <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.
| |
| </li>
| |
| <br>
| |
| <li style="list-style-type: decimal;">
| |
| Adjust the channel gain with the R1 remote control<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.
| |
| </li>
| |
| <br>
| |
| <li style="list-style-type: decimal;">
| |
| 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.
| |
| </li>
| |
| </ul>
| |
| <p>
| |
| | |
| 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.
| |
| </p>
| |
| | |
| === What is the recommended way to set the gain for a Model I system when using it with a T1 ToneMatch audio engine? ===
| |
| | |
| <li style="list-style-type: decimal;">
| |
| Make sure the power switch on the power stand is in the Off position and the remote control is disconnected<br>
| |
| <i>Note: The remote should be disconnected so that the ToneMatch audio engine solely controls the volume of the {{L1}} system.</i>
| |
| </li><br>
| |
| <li style="list-style-type: decimal;">
| |
| Make sure the ToneMatch audio engine power switch is in the Off position and its power supply is connected
| |
| </li>
| |
| <br>
| |
| | |
| | |
| <li style="list-style-type: decimal;">
| |
| Set the ToneMatch audio engine master volume control to 0
| |
| </li>
| |
| <br>
| |
| | |
| <li style="list-style-type: decimal;">
| |
| 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}} power stand <br><i>
| |
| 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>
| |
| </li>
| |
| <br>
| |
| <li style="list-style-type: decimal;">
| |
| 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>
| |
| | |
| </li>
| |
| <br>
| |
| | |
| | |
| <li style="list-style-type: decimal;">
| |
| Turn on the ToneMatch audio engine
| |
| </li>
| |
| <br>
| |
| <li style="list-style-type: decimal;">
| |
| Turn on the {{L1}} power stand
| |
| </li>
| |
| </ul>
| |
| | |
| === Do the mic inputs have phantom power? ===
| |
| Yes. The primary input channels 1 and 2 have a button selector for +24V phantom power for microphones that require it.
| |
| | |
| === I thought phantom power was 48 volts. Why does the power stand only supply 24 volts? ===
| |
| Phantom power is a DC voltage that powers the preamplifier of a condenser microphone. It can be in a range of 11 – 48 volts.
| |
| | |
| === What input connections will channels 1 and 2 accept? ===
| |
| 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
| |
| | |
| === Why don't channels 3 and 4 have presets, XLR inputs and line outs like channels 1 and 2? ===
| |
| The {{L1}} 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}} system. The remaining channels are suitable for additional direct instruments, mixers and MP3 or CD players.
| |
| | |
| === What are the critical frequencies (Q-points) of the remote control? ===
| |
| 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."
| |
| | |
| === Will an {{L1}} Model I system still work without the remote control? ===
| |
| 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.
| |
| | |
| === Is the remote control cable an off-the-shelf MIDI cable? Are there extensions available? ===
| |
| 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.
| |
| | |
| === 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? ===
| |
| 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.
| |
| | |
| === Does an {{L1}} Model I system have built-in effects? ===
| |
| 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.
| |
| | |
| === Can I use effects equipment with the {{L1}} Model I power stand? ===
| |
| 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}} system. It features a complete suite of studio-class effects and processing.
| |
| | |
| === How can I add more inputs to my system? ===
| |
| Use our multichannel {{T1}}, specifically designed for {{L1}} 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}} Model I power stand.
| |
| | |
| === What's the "data out" connector for? ===
| |
| 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.
