- Channels 29-32: Simplified interface with Level, AUX1, and AUX2 dials, ideal for signals not requiring extensive EQ (e.g., laptop backing tracks, drum machines).
3.3 Effects Processors
The mixer includes two independent 24-bit stereo FX processors with 99 presets.
- Select desired effects (reverb, chorus, flanger, delay, pitch shifter, multi-effects) using the program controls.
