Operating Instructions
Channel Control
- GAIN Control: Adjust the red GAIN knob at the top of each channel to set the input sensitivity. Use the -20dB PAD switch for very hot signals to prevent clipping.
- Equalizer (EQ): Each channel features a 3-band EQ (HF, MF, LF) to shape the tone of the input signal. Turn knobs clockwise to boost frequencies and counter-clockwise to cut.
- AUX/FX Control: Use the blue AUX/FX knobs to send a portion of the channel's signal to external effects or monitor mixes.
- PAN/BAL Control: Adjust the PAN/BAL knob to position the channel's signal within the stereo field (left to right).
- ON Switch: Activates or deactivates the channel.
- Channel Faders: Control the overall volume level of each individual channel.
- MAIN Switch: Routes the channel's audio directly to the main output.
- PFL (Pre-Fader Listen) Switch: Allows monitoring of the channel's signal through headphones before it reaches the main mix, useful for gain staging.
