Connect the T8S to L1 Model II

The output from the T8S ToneMatch mixer is a balanced mono 1/4 inch (6.35 mm) Tip-Ring-Sleeve and the input on the L1 Model II is a balanced mono 1/4 inch (6.35 mm) Tip-Ring-Sleeve so use a cable like this.

1/4" Male TRS to 1/4" Male TRS  Cable.

Connect the ToneMatch Power Supply to the T8S ToneMatch mixer for power.

Set the L1 Model II Analog Input Trims to about 9:00 o'clock.

Analog input trim (volume, or gain) control

Setting the trim level on the Model II Power Stand is a one-time step. Once you have matched the output of the ToneMatch mixer to the input of the L1 you don't need to adjust it again.

  1. Set the Trim control on the power stand to the 0 (zero) position.
  2. Connect the T8S ToneMatch mixer Main Output to the Analog Input
  3. Adjust the volume of the T8S ToneMatch mixer Main Output to the maximum output without distortion. This is probably between 10:00 o'clock and 12:00 o'clock on the Master Output
  4. While playing the source, increase the Trim level so that the Signal/Clip indicator glows green or yellow. This will probably be around 9:00-11:00 o'clock
  5. If the Signal/Clip indicator glows red, decrease the Trim level so that it glows only green or yellow.
