Each input channel features controls for gain, equalization (high, mid, low), monitor send, FX send, pan, and level. Adjust these to achieve the desired sound for each input source.
3.2 Master Section
The master section includes controls for the main mix level, monitor mix level, and built-in effects processor. The dual 7-band graphic EQs allow for precise frequency shaping of the main and monitor mixes.
3.3 Effects Processor
The PMH880S features a dual 24-bit stereo FX processor with 99 presets. Use the PROGRAM knob to select effects and the FX SEND controls on each channel to route audio to the effects processor.
