Signals at these jacks will depend on the levels set by the main mix fader. Rca unbalanced wiring: tip = hot, sleeve = shie...

Aux these knobs tap a portion of each channel signal and send it out, via the aux sends (10) jacks, to an amp & speakers for stage monitors or to an ef- fects device for parallel effects processing. Each aux knob’s level ranges from off, through un...

20 eq: (28 through 34) the mixer has low shelving, mid peaking and high shelving eq. “shelv- ing” means that the circuitry boosts or cuts all frequencies past the specified frequency. For example, boosting the low eq knob boosts bass frequencies at 80hz and below. “peaking” means that only a selecte...
