A.The Channel 1 and Channel 2 inputs are each equipped with a VOLUME knob to adjust the input volume and TREBLE, MIDDLE, and BASS knobs to adjust the tone.
In addition, the Channel 2 input incorporates chorus, vibrato, distortion, and reverb effects (these are unavailable when using Channel 1). Also, use Channel 2 if you wish to use the rear panel SEND/RETURN jacks.
