Right outputs and the Headphone output.
10) INPUT KNOB - Controls the level of the signal at the TEC8G's input
stage.

jam sessions. The Jam-a-Long™ signal is mixed with your instrument
signal at both the main and headphone outputs so you can play along
with your favorite tunes.
4) LEFT / MONO OUT - For stereo applications, this is the Left main out-
put. Use this jack for mono applications.
