MASTER / BOOTH OUTPUT
This section of the mixer features controls and indications for the master and booth outputs.
MASTER LEVEL
This control adjusts the level of the master output volume on both the balanced and unbalanced outputs. At the fully anti-clockwise
position there will be no sound. As the control is moved in a clockwise direction the output level will be gradually increased until, at
the fully clockwise position, the output level will be at its maximum.
OUTPUT PROTECTION LIMITER
The output protection limiter protects the main outputs from clipping. As the signal level approaches the clip point of the DACs, the
limiter reduces the output gain, until the audio level decreases back to below the limiter threshold, at which point the gain returns to
normal. If the red LEDs are active, then the limiter will be working to maintain the signal quality. It is good practice never to clip the
mixer.
LEVEL OUT METER
These indicators show the left and right master output volume from -15 to +5. The indicators from -15 to -3 are coloured blue, the
indicators from -1 to +3 are coloured white, and the peak indicators +5 are coloured red to identify output overload conditions.
BOOTH LEVEL
This control adjusts the level of the booth output volume on both the balanced and unbalanced outputs. At the fully anti-clockwise
position there will be no sound. As the control is moved in a clockwise direction the output level will be gradually increased until, at
the fully clockwise position, the output level will be at its maximum. There is no level indicator for the booth output.
MONO/STEREO SWITCH
This switch is to sum the Stereo signal to a Mono signal. It acts on the master outputs and booth outputs.
HPF 80Hz SWITCH
Apply this switch when you are suffering from Bass Rumble from the deck/phono input.
