Operating Instructions
1. Channel Controls
Each input channel (1-6) features dedicated controls for optimal sound shaping:
- GAIN: Adjusts the input sensitivity for microphones or line-level signals. Set this to achieve a strong signal without clipping (PEAK LED should not light up consistently).
- PAD/HPF: Attenuates the input signal (PAD) or applies a High-Pass Filter (HPF) to remove low-frequency rumble.
- 3-Band EQ (HIGH, MID, LOW): Adjusts the treble, midrange, and bass frequencies for each channel.
- EFF Send: Controls the amount of signal sent to the internal DSP effects processor.
- PAN: Adjusts the stereo position (left to right) of the channel's signal.
- LEVEL: Controls the overall volume of the channel.
