=== 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.


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 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.
{{T1 Gain Microphone}}


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.  
* Instrument
:Turn your input as high as it is likely to go during performance.


If the T1 trim is going red, you should back off, you are definitely nearing or in compression.  
=== 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:T1TrimPotGreenYellowRed.png|T1 Trim Pots - Channels 1 and 2 are okay. 3 is set too high]]  
[[Image:TrimlightsOK.gif]]


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.  
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.

Note: New recommendation is '''3''' see below.


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.

For these conditions:

*T1 going into model I/Classic into Ch 3/4
{{:T1 ToneMatch® Audio Engine / Aux}}
*balanced OR unbalanced 1/4" cable
*remote unplugged, OR, master volume on remote at 12 o clock
*proper gain staging required on the T1 itself


I'm going to revise the original recommendation of '''2''' for Ch 3/4 to '''3''' - under the above conditions.
== &frac14; inch jack Output Connections ==


This will give you the same gain going into the L1 Classic/model I as if you were going through the digital ethercon input on a model II.
{{:T1 ToneMatch® Audio Engine / 1/4 inch Output Connections to L1® Family Members}}


If you are using the remote on your M1/CL, then you will need to compensate a bit. If you running the remote master volume at max, then stick with '''2'''on Ch 3/4. I would recommend against running the master volume below 12 o'clock when using a T1.

Without getting too deep into technical stuff, with regards to the T1 the two ways to interface with a {{Model I}} are:
== Effects  ==


1.) The way we generally recommend - 1/4" out from the T1 into Ch 3/4 with the Level at '''4'''.
=== Overview from Hilmar-at-Bose  ===


2.) 1/4" balanced {{TRS}} from the T1 to XLR input of Ch 1/2. Of course this requires a TRS to XLR cable which most folks don't have lying around - but is a common studio connector available at GC etc.
{{:T1 ToneMatch® Audio Engine / Effects}}  


Both ways are equal as long as your distance from the model I is less than 25 or 30 feet. Longer than that I would lean toward option #2.Method #1 allows you not to use a preset Channel on the model I.

==Input / Output Levels ==
=== Input Level ===
{{T1® Prefs Input Level}}


The {{T1}} comes with a really nice Pro Ethercon cable, with robust metal connector shells and an almost memoryless 18' black cable.
=== Output Level ===
{{T1® Prefs Output 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.
== Cables  ==


Later in that discussion Hilmar-at-Bose tells us:
=== From T1 to Model II  ===


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.
{{:ToneMatch® Cable}}  
 
It's certainly a quick and cheap way to get a spare for an emergency.
 
=== Convert Cat-5 Cat-6 to Ethercon  ===

=== Cable Length  ===
 
==== 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>
 
A 33 or 50 footer will not cause any problems, either with the digital audio (ones and zips) or the power.
 
The technical reason follows, for those who are interested&nbsp;: 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).
 
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.
 
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.
 
==== Over 50 feet  ====
 
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>
 
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.
 
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.

== Compatibility with Other Members of the L1® Family of Products ==
{{L1 Compatibility}}


In 23 years at Bose, the {{Model II}} and {{T1}} 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.


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.
