There is a large variety of effect processors out there with many different types, qualities, and prices and unfortunately there isn't a one-size-fits approach. Not the least factor is that a lot depends on personal taste and preference.
*Fixes and Enhancements
**[[L1® Model II Power Stand Firmware Updates|L1® Model II Power Stand Firmware Updates]] - includes bug fixes
**[[T1 ToneMatch® Audio Engine Firmware Updates|T1 ToneMatch® Audio Engine Firmware Updates]] - includes bug fixes


Our intention with the {{T1}} was not necessarily to build the "world's best effects" but solid usable tools that the musician can deploy in a live situation as the situation requires. We've evaluated effect processors that are popular for live performance and used that to guide our own development. We've also tried to limit the complexity of the user interface, i.e. we provide only the most useful parameters for a certain effect and have pre-tuned the more esoteric ones.
*Download Presets for your T1®

'''<big>[[T1 ToneMatch® Audio Engine / Videos|T1® Videos]]</big>'''
{{:T1 ToneMatch® Audio Engine / Videos}}


This being said, the {{T1}} has a couple of things that are different from most effects processors: The processing power devoted to this is substantial. The processing chip we use operates in 32-bit floating point and has a peak performance of about 2 billion operations per second (2 GFlops). That is a lot more than can be found in typical processors of this type.

*[http://www.bose.com/controller?url=/shop_online/speakers/portable_amplification_systems/accessories/l1_tonematch_acc.jsp T1 ToneMatch® Audio Engine - Official Bose Page]


This enables us also to run individual effects on all 4 channels. You can use different combination of compressor/limiter, chorus/flanger, delay, parametric EQ, etc. on each channel. The only thing that is shared is reverb. This is equivalent of having pretty much 4 multi-effects processors at the same time. This enables the user to fine tune and tweak the effects settings for each individual instruments without having to compromise between channels.
*[[Presets (T1 ToneMatch)|T1 ToneMatch® Presets]] (includes downloadable lists with cross-references to Version 2 presets).  




There is also some fairly unique processing such as kick-gate (for drums), zEQ and ToneMatch, that is not available from any other device I'm aware of.

Again, in the end each user will have to decide whether we have found the "sweet spot" or not, but I'm confident that these effects will work well for many users.


Hope that helps

When using the Classic or Model I <ref>Hilmar-at-Bose talks about setting inputs [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/3041050644?r=2991039944#2991039944]</ref>
The T1 has more input capbility then the Model 1,s so you should be able to use the T1 as the only control for your system. We have a recommended trim setting for connecting the T1 to a Model 1 input Ch 3 or Ch 4 (I think it's 2). With this setting you will not distort or clip the Model 1 no matter what you do on the T1. You can even use the Model 1 without the remote.


The T1 controls are a heck of a lot faster then the R1 controls. There is no perceivable lag.

Your first adjustment for any input to your {{T1}} is the Trim setting. The exact position of the Trim will vary depending on signal strength of your input source. The correct setting for any particular source may be different from your other sources.

=== Set Up Your Source ===
Set your source at the maximum that it will be when performing.
* Microphone
:Sing directly into the microphone using close microphone technique (lips just brushing the windscreen). Sing as loudly as you will sing during your performance. You want to set the Trim to work at your maximum volume.
 
{{T1 Gain Microphone}}
 
* Instrument
:Turn your input as high as it is likely to go during performance.
 
=== Set Input Trim ===
Turn the Trim setting up until the Trim Light is solid green with occasional flickers of yellow. Use the Trim lights as your guide. (The exact position of the Trim knob is not important).
 
[[Image:TrimlightsOK.gif]]
 
If you see flickers of red (below), turn the Trim down. You are definitely nearing or in compression. Turn the Trim down until there are no red flickers.

:One difference in gain staging the T1 and the Classic is that the T1 has a three-stage trim LED. It lights up green when a signal is present, yellow when you are getting pretty loud (8 to 10 dB of headroom left), and red when you dangerously close to or at full scale.
 
:In a way, the yellow trim on the T1 is similar to how you treat the red on the Classic. Some yellow during peaks is good on the T1, just like some red on the Classic is good.
 
:If the T1 trim is going red, you should back off, you are definitely nearing or in compression.
 
:A really helpful feature on the T1 is to go to the Prefs/Output Level menu, and see where you are relative to maximum output.

[[Image:T1 Inputs.png|T1 Inputs 1,2,3 and 4/5]]
 
The following notes about Channels 1,2,3, 4/5 are from Hilmar-at-Bose spread out over several posts in [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=2981027944#2981027944 Information on the new T1 ToneMatch audio engine]
 
Channels 1,2,3 support
 
*Balanced XLR
*Unbalanced Tip-Sleeve
 
The Tip-Sleeve inputs are high impedance so you can plug in an acoustic guitar with passive piezo pickup or any other passive instrument directly without a pre-amp. Input impedance on Channels 1,2,3 is about 1 MOhm. Channels 4 and 5 have an input impedance of about 10 kOhm.
 
:Choosing the "best" input impedance is a little bit of a trade off and matching the pickup's impedance is not necessarily the best choice.
 
*Piezo pickups are also somewhat of a capacitor and together with the input impedance of the preamp, this forms a low pass filter.
*If the impedance is too low, then the low pass filter is in the audible range and the guitar loses sparkle and gets a little dull.
*If the impedance is too high, the system gets noisy and somewhat sensitive and finicky. For example, stepping on or simply moving a cable changes its capacitance which creates clearly audible artifacts with a very high input impedance.
*We feel, that 1 MOhm is a very good compromise for a live application.
 
[http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=7571094084#7571094084 Bill-at-Bose gives us the following insights into Channels 1,2,3 and 4/5]
 
*For inputs 1-3, you can physically plug a TS or TRS 1/4" plug into the jack, and get perfect fidelity.
*If you have a balanced line source and TRS cable, and plug into an unbalanced input (1,2,3), you may not get as much resistance to induced noise or potential ground loop hum as you will if you plug into the balanced inputs (4,5).
*Our Master and Aux outputs are actually balanced, so you will have an advantage on noise if you use a TRS, but they accept a TS also. So there we also wrote that they "accept" both TS and TRS.

... (the preamps on the Model I are)... exactly the same as the Classic.
 
On the {{T1}} they're different, but are designed to the same standard as the {{Classic}} preamps.
 
Functionally they are basically the same in terms of frequency response, input impedance, noise performance, max gains etc.
 
The difference comes in how we get there. I'll try not to go into horribly boring detail. The name of the game is trade-offs, and in the end the design constraints dictate the *best* type of circuit used for *this* particular situation. Here are a couple of the many factors that dictate the differences:
 
Gain structure. The internal components of the {{T1}} are different that the {{Model I}} / {{Classic}} and need to have signals fed to them in certain ways. Different designs are more suited to the levels needed than others.
 
Physical layout of the circuit on the board. There are four channels in a tighter space in the {{T1}}. Again, certain designs lend themselves to be better at this than others.
 
After evaluating all of the factors that go into the design of a preamp we are using another proven circuit that relies more on discrete transistors rather than op-amps. It fits our needs better for this design situation. The preamp design itself is not necessarily any better or worse. There are *many* ways to skin the cat of preamp design to achieve a desired performance.
 
Will it sound different? No...I certainly cannot hear a difference playing through it. Can't measure one either.
 
Hope this sheds some light on it.

The T1 ToneMatch™ audio engine comes with a really nice Pro Ethercon cable, with robust metal connector shells and an almost memoryless 18' black cable.
==Input / Output Levels ==
=== Input Level ===
{{T1® Prefs Input Level}}


However, in a pinch, should you forget the cable, or if say a huge Hammond B3 gets dropped on the cable and severs it, YOU CAN USE ANY ORDINARY CAT 5 ETHERNET CABLE and it will work fine until you replace you nice fancy T1 cable.
=== Output Level ===
{{T1® Prefs Output Level}}


Later in that discussion Hilmar-at-Bose tells us:
== Cables  ==


Any CAT5 (or CAT5e, CAT6, or CAT7) cable will work just fine without any degradation at least initially. The downsides are that most ethernet cables don't coil particularly well and that the connectors wear out over time. After a a few hundred uses you may notice the occasional drop out, at which point it's time to get a new one.
=== From T1 to Model II  ===


It's certainly a quick and cheap way to get a spare for an emergency.
{{:ToneMatch® Cable}}


=== Cable Length ===
== Power Supply  ==
==== Up to 50 feet ====


A technical note from Bill-at-Bose <ref>Bill-at-Bose talks about [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5711086844?r=3931015654#3931015654 cable lengths]</ref>
{{T1ps}}


A 33 or 50 footer will not cause any problems, either with the digital audio (ones and zips) or the power.
5 foot of cord from the T1 to the switching power supply, and a removable 6 foot cord from the power supply to the wall. This is very similar to a laptop power supply.  


The technical reason follows, for those who are interested : A 24 gauge wire (the size typically used in ethernet cables) has about 2.5 Ohms of resistance per 100 feet. The T1 draws roughly 1/4 Amp on each of two supply wire pairs (+/-18V nominal).
== Microphone Stand Bracket (optional) ==


For a 50 foot run, each pair of wires (made up of a plus and minus lead) totals 100 feet. A quarter Amp of current across 2.5 Ohms gives, per Ohm's law, a voltage drop of less than one volt (V=IR = 0.625 Volts). Because of the margin we built into the system, it can handle this voltage drop easily.
{{:T1 ToneMatch® Audio Engine / Microphone Stand Bracket}}


In fact, although we don't recommend it and can't guarantee it, the digital audio has been tested up to 100 feet in average conditions (for example, no undervoltage on the AC supply at the gig), and quite happily continued to make music.

MikeZ-at-Bose added in a later discussion:<ref>MikeZ-at-Bose [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/8501089064?r=4311000164#4311000164 talks about T1 cable lengths]</ref>
== Display Panel  ==


Bill at Bose stated you could run 50' of ethernet cable no problem at all. Success at distances longer than that would start to depend on outside factors, for instance the voltage of your power source.
=== Outdoors ===


Another option for you is to run the {{T1}} off of the optional power supply, and then run a balanced line from the Master Out on the {{T1}} to the balanced 'analog input' on the {{Model II}}. This method would be able to transmit over a hundred feet, perhaps much more.
Q: Please talk about using the {{T1}} outdoors. Will I be able to see /read the display? A: Should be no problem. The LCD display on the T1 is "transflexive". In dark conditions the blue backlight will shine through the "transmissible" part so everything is easily visible. In bright sunlight, it becomes "reflexive" just like a piece of paper. The backlight may wash out (i.e. it will not look really blue anymore) but it's still clearly visible. <ref>Hilmar-at-Bose talks about the [http://bose.infopop.cc/eve/forums/a/tpc/f/7521050644/m/5031050644?r=4091059454#4091059454 transflexive display on the T1®]</ref>

In 23 years at Bose, the L1™ model II and T1 ToneMatch™ audio engine are the most lovingly designed products I have ever had the fortune to work on. More care by more experienced people went into this than anything I've been involved in.
{{:T1® and Model II Design Team}}


The most minute details were studiously created. As one tiny but important example, a propriety light pipe was designed so that the light from volume knob indicators smoothly wrapped around the knob from top to side, giving the musician a clear indication of volume from any angle. The color and intensity of the light was carefully designed so that it was visible in an extraordinarily wide range of stage lighting conditions.
