If you need to playback stereo tracks from a USB from your computer, this how you can do it.
NOTE: You will want to control the volume and balance from your computer. It is not convenient to do this from the T1 ToneMatch Audio Engine in this configuration because one of the channels is routed through the T1 ToneMatch Audio Engine Aux buss and the other is through the Master. It is not easy to control both of these at the same time on the T1 ToneMatch Audio Engine.
Equipment Required
L1® Classic/Model I or Model 1S or Model II or Compact (L1® LEFT)
L1® Classic/Model I or Model 1S or Model II or Compact (L1® RIGHT)
If one of the L1®s is a L1 Model II then you will not need the connection marked "To L1 RIGHT". This will be replaced by the ToneMatch® connection to the L1® Model II.
USB to PC
We want to split the USB signal from the computer so that
the Stereo Left channel goes through Channel 4/5 to Aux and from there to an analog connection to an L1®
the Stereo Right channel goes through to Master and from there to an analog connection or digital connection to another L1™
Prefs
Turn the main selector to Prefs.
Select USB from PC
Set Left: Ch 4/5
Set Right: Master
Channel 4/5
Press Chan 4/5 CH Edit
Rotate the selector to Aux
Set the Level to 0% (not bypass)
Set the Tap to Pre
Mute this Channel. You can turn down the level as well. It you leave the Mute off then you will be sending both Left and Right stereo signals to the Main output.
Setting the Relative Levels
On the Computer: Start playing a track. Turn up the volume on the computer a little. You won't hear anything yet.
On the T1® Turn up the Master Volume. You should be hearing the Stereo Right channel.
Work the volume on the computer and the T1® until you are happy with a workable volume level.
On the T1® Turn up the Aux Level. Your setting will look something like this. The actual value you set may be different. That's okay.
This is the Stereo Left channel. Bring up the volume until it matches the output from the Master. Note: This Aux volume is completely independent of the Master volume. This is why you want to set it to be equally balanced with the Master. You will then be able to control the balance and level from the computer.
Download Shared Scene
Here is a Shared Scene you can load into your T1 ToneMatch Audio Engine. If you have been following along and have set up our T1 ToneMatch® Audio Engine with the settings above, you do not need to download this Shared Scene. I just included this as a convenience in case you wanted to try the Shared Scene system.
This scene has very generic settings for Channels 1,2 and 3 and the settings discussed in this article for Channel 4/5.
Channels 1,2,3 are set to Vocal Microphones: Handheld Microphones - no effects, muted.
Channel 4/5 is set as described above with USB routed to 4/5 routed to Aux. This is muted so that this Channel is not sent to the Main output.
Please read the entire article before using this Shared Scene. It is provided as a convenience to save you some time is you want to have the same settings.
Warning
This is an experimental file and I strongly recommend that you back up all your scenes before loading this one, just in case you overwrite something by accident. I have tested this and it works in my environment, but I cannot accept responsibility for any issues you may have when you apply it to your T1 ToneMatch® Audio Engine
You will need to understand how to use the L1 Software Updater program to load this Shared Scene.
Things you must have and understand to use a Shared Scene
These are the latest versions of the ToneMatch Updater application.
To update your L1 Model II with a T1 ToneMatch Audio Engine use the older version of the L1 Updater software
L1® Updater Software application. Note: This is required to do any updates for the T1 ToneMatch® Audio Engine and L1® Model II Power Stand. (Two versions available)

Various versions of the Mac OS cannot identify Bose as a developer. The Mountain Lion version of OS X (10.8) includes a feature called Gatekeeper to protect users from installing applications of non-Apple identified developers. The Mavericks version of OS X (10.9.5) temporarily cannot identify Bose as a developer as well.

If your firmware update is not successful - Caution
After you update the T1 ToneMatch Audio Engine or L1 Model II firmware, if you see a window on the PC that says the update was not successful, you should:
turn the L1 and T1 off
wait three seconds
then turn the L1 and T1 back on
Do this before trying the update again!
This allows the L1 and T1s to re-establish a good copy of the software.
On the L1® Classic / L1® Model I set the Power Stand Input Level to 3. You may want to fine tune that a bit but it should be a reasonable starting point.
Two Model IIs
For the L1 Model II with the Analog connection - try setting the Analog input trim 3. You may want to fine tune that a bit but it should be a reasonable starting point.
Two Model 1S
For the L1 Model II with the Analog connection - try setting the Analog input trim 3. You may want to fine tune that a bit but it should be a reasonable starting point.
Two Compacts
For the L1 Compact connect to Channel 2 with the volume straight up. You may want to fine tune that a bit but it should be a reasonable starting point.
