T1 ToneMatch® Audio Engine / USB / Output Stereo to Two L1®s
|
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)
- T1 ToneMatch Audio Engine
- T1 ToneMatch® Audio Engine power supply (required unless one of your L1®s is a L1 Model II).
Initial Connections
Turn down the outputs and volume
Start with your computer with the volume set all the way off, muted or at least really low. Things can get loud very quickly if you are not careful.
On the T1® turn down the Master Volume and mute all Channels.
Physical Connections
Make the following connections. If you are running two L1 Classics or L1 Model I or L1 Compact Systems, then you will also need the optional T1 ToneMatch® Audio Engine power supply (not shown below).
Model II
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.
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.

Warning
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.
Source: If your firmware update is not successful - Caution
Here is a very simple Scene that includes the setup described above.

Variations
One Classic / Model I and One Model II
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.
Two F1
