1. TRIM CONTROLS 1~9
These knobs provide continuous control of pre-amp gain from +14dB to +58dB.
2. SIGNAL INDICATORS 1~9
These LED indicator light when signal source come in.
3. PEAK INDICATORS 1~9
These LED indicators light when the input signal to the associated channel is 3dB below clipping. If the
indicator is lit steadily, reduce the channel’s Trim level (1) to avoid distortion.
4. CHANNEL FADERS 1~9
These are the main output level controls for each channel. They provide continuous control of the signal level
sent from the associated input channel to the master output buss. Faders of unused channels should be set to
fully anticlockwise.
5. AUX INPUT LEVELS (AUX1, AUX2)
These knobs provide continuous control of the levels for signals connected to the rear-panel Aux 1 and Aux 2 inputs.
6. MASTER PEAK INDICATOR
These LED indicators light when the master output signal is 3dB below clipping. If the indicator is lit steadily,
reduce the master output level (7), or the levels from the active input channels (4) to avoid distortion.
7. MASTER OUTPUT CONTROL
This is the controller that adjusts the level of the master output which is a mixture of each channel’s signal.
