■ Master Control Section © Stereo master faders
The stereo master faders independently adjust the level
of the left and right channel main stereo program buss
signals appearing at the ST OUT connectors.
@ STEREO ON switch
Turning this switch ON will turn the main stereo buss
signals on and off. This switch is located before the fad­
ers and before the meters in the signal chain. In other
words, if this switch is OFF, no signal levels will be
shown on the main STEREO meters. The signal sent
out to MIX is unaffected by this switch.
© Stereo CUE switch
Turning this switch ON sends the main stereo program
buss signal, in stereo, to the stereo PHONES jack, via
the CUE/PHONES fcontrol. The stereo CUE switch
should be turned ON to permit headphone monitoring
of the main stereo program, but it must be turned OFF
to individually monitor input channel or AUX buss cue
signals.

) AUX RTN 1 and AUX RTN 2 controls
These controls adjust the level of the signal received at
the rear-panel AUX RTN jacks and mixed into the main
stereo program. Since stereo AUX returns are provided
(AUX RTN 1 L & R, AUX RTN 2 L & R) the AUX RTN
controls simultaneously adjust the level of the signals
appearing at the corresponding L and R return inputs.
The returned L and R channel signals are sent to the L
and R stereo buss lines. If only a single-channel signal
is returned (i.e. a plug is inserted into only the L or R
return jack), the signal will be fed to both the L and R
channels of the stereo buss.
Note that there is no dedicated AUX RTN3 control. If
you want to return a signal from any device connected
to AUX3, you should reroute it to one (or two, if stereo)
of the input channeis.
) MIX ON switch
This enables or disables the routing of the L and R sig­
nals to the MIX outputs. The MIX outputs may be used
for making a simpie recording of a live performance, or
may be used to drive a second set of power ampiifiers
and speakers for phase compensation, etc.
