OPERATION

Front Panel Controls
Channel Controls (1-8)
CH 1 SOURCE SELECT
This pushbutton switch selects whether the Channel 1 signal comes from the 1/4" line jacks or the
XLR microphone jack. In the LINE (out) position, the line signal is selected. Pushing the button in
(MIC position) lights the switch green and selects the microphone signal.
LEVEL
Each of these controls adjusts the level of the associated input channel and determines its
contribution to the overall mix. Normally, for best noise performance and to minimize distortion, you
should adjust each control so that its associated green SIGNAL LED is on continuously and its red
CLIP LED never comes on or comes on only very briefly during the loudest audio passages.
PAN
Each of these controls adjusts the relative position of the associated input channel in the overall left-
right panorama. Fully counterclockwise is Left and fully clockwise is Right. For a stereo signal, this
control could also be considered a balance control.
EFX SEND
Each of these controls adjusts the amount of signal of the associated input channel that is sent to an
external effects processor, if connected. Note that this control is located after that channel's LEVEL
control in the signal path, so that the channel level sent to an external effects processor will also be
affected by the setting of the LEVEL control.
Master Controls
LEVEL
This control adjusts the overall level of the mixed signal output to the MAIN OUT jacks. Normally you
would adjust this so that the LEFT and RIGHT MASTER LEVEL meters stay in the green most of the
time and the yellow LEDs light only during the loudest audio passages. The red CLIP (+20) LEDs
come on just before the onset of audible distortion.
