Inputs, Outputs, and Controls
Inputs (bottom row jacks)- Patch up to four inputs signals to these.

Bass/Treble knobs- These are shelf-type filters that cut or boost bass and treble respectively. A setting of 5 (middle) is flat.
Master 1-4 level knobs- Sets the master level of busses A, B, C, and D respectively.
