16 FX BUS OUTPUT (EFX only) (Aux 2 on EPM)
This impedance-balanced output carries the signal from the FX bus. It could be used as a second Aux Output if desired, if the FX Processor is not needed at the time. The FX sends on the inputs channels to the FX bus are always post-fade.

Footswitch Input (see diagram on page 20) - Using a single-pole, momentary footswitch inserted into the FOOTSWITCH input the effects processor can be muted/un-muted.
18 STEREO RETURN INPUTS (EFX only)
This pair of inputs accept 3-pole ‘A’ gauge (TRS) jacks. Use these inputs for sources such as keyboards, drum machines, synths or CDs. The inputs are BALANCED. Mono sources may be used by plugging into the left jack only.
19 STEREO RETURN LEVEL (EFX only)
This control sets the level of signal routed to the main mix busses. There is an associated PK LED to warn of signals which are too high.
