FRONT PANEL FEATURES
1.CHANNEL LEVEL
Manual Mode: In the manual mode the channel level controls provide 6dB of gain and 50dB of attenuation.
Auto Mode: In the auto mode the control still provides 50dB of attenuation, but the control does not add gain to the overall system level. Instead, when the level is adjusted above Ò0Ó, the other channels are attenuated to make the channel being adjusted sound louder in the mix without adding to the system gain.
2.MASTER LEVEL
The master level controls the overall output level. The range is set for 10dB of gain above, and 40dB of attenuation.
