This is how you can connect a T4S ToneMatch® mixer to an L1® Model II and an L1® Model I.

L1 Model I

Connect one T4S ToneMatch® mixer 1/4 inch (6 mm) main output to the L1 Classic channel 1. Use a 1/4 inch (6 mm) Tip-Sleeve cable.

With the T4S ToneMatch® mixer master output around 11:00 o'clock and running some inputs at the maximum you will use in performance, set the L1 Classic input trim level so you get solid green lights with occasional flashes of red.

You don't need to use the R1 Remote when you're using the T4S.

Set the ToneMatch Preset to 00.

Questions

Why not use the XLR output on the T4S ToneMatch® mixer and XLR input on the L1® Model I
> The XLR outputs from the T4S are too hot for the XLR inputs on the L1® Model I
Should I use 1/4 inch (6 mm) Tip-Ring-Sleeve cables for a balanced connection?
> No need. The 1/4 inch (6 mm) inputs on the L1 Classic are unbalanced. You can use balanced cables but there's no advantage



L1 Model II

Connect the one T4S ToneMatch® mixer T4S 1/4 inch (6 mm) main output to the L1 Model II Analog Input. Use a 1/4 inch (6 mm) Tip-Ring-Sleeve cable.

With the T4S master output around 11:00 o'clock and running some inputs at the maximum you will use in performance, set the L1 Model II input trim level so you get solid green lights with occasional flashes of red. This may be different than the setting on the L1 Model I.

Questions

Why not use the XLR output on the T4S ToneMatch® mixer
> This is a matter of convenience. When you use 1/4 inch (6 mm) Tip-Ring-Sleeve cables, both ends work in both devices.
Should I use 1/4 inch (6 mm) Tip-Ring-Sleeve cables for a balanced connection?
> Yes. The 1/4 inch (6 mm) output from the T4S is balanced. The analog input on the L1 Model II is balanced. Use a 1/4 inch (6 mm) Tip-Ring-Sleeve cable to maintain a balanced connection.
How do I balance the relative volume between the two L1 systems?
> Do this by ear. If you start off with both responding with solid green lights (red flickers are okay), then turn down the one that is too loud.
