1. TRIM CONTROLS 1-8
These knobs provide continuous control of the gain level for the associated input channel.
2. PEAK INDICATORS 1-8
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.
3. GAIN SELECT SWITCHES 9/10 – 11/12
These switches select the input gain level for Stereo Channels 9/10 and 11/12. You may select between
+4dB, -10dB or –20dB input level, depending on your input source. If the signal is too weak (very low level),
select a higher setting; if the signal is too hot (overloaded and distorted), select a lower setting.
4. EQ CONTROLS
These knobs provide continuous control of equalization for the stereo (master) output. Three bands of
equalization are provided:
Low: 80Hz, ±12dB, Shelving
Mid: 800Hz ±12dB, Shelving
High: 8kHz ±12dB, Shelving
5. MAIN OUTPUT LEVEL CONTROLS
These sliders provide control of the stereo (master) output level. The output level may be monitored
by the Output Level Meters (6).
6. OUTPUT LEVEL METERS
These ve-segment LED meters monitor the level of the stereo (master) output signal.
