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™ in this configuration because one of the channels is routed through the T1™ 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™

Equipment Required

  • L1™ Classic of Model I or Model II (L1™ LEFT)
  • L1™ Classic of Model I or Model II (L1™ RIGHT)

If you have one of each then use the Model II as L1™ RIGHT.


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 Model I Systems, then you will also need the optional AC Power Adapter connection (not shown below). If one of the L1™s is a Model II then you will not need the connection marked "To L1 RIGHT" as this will be replaced by the connection to the 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 a n 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
  • Ensure that this channel is Muted. 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.

Shared Scene

Here is a very simple Scene that includes the setup described above.
