Operation
(24) STEREO AUX RETURNS
(LEFT/MONO, RIGHT)
(16) AUX RETURN CONTROL
The Aux Return jacks are the mono
or stereo returns for Aux Send (25).
If you connect a signal to the
Left/Mono Return jack only, the Aux
Return will operate in mono and the
signal will be routed to the Aux
Return Control (16) and then mixed
into the left and right Master Mix
Stereo Outputs (23). The separate
left and right return jacks are provid-
ed for use with stereo signals such
as those from the output of a stereo
effects processor. The left and right
return signals will be routed to the
Aux Return level control (16) and
mixed into the left and right Stereo
Out (23), while maintaining stereo
separation. The Aux Returns are
multi-functional. They may be used
for returning the outputs of effect
units, such as Tape Returns from a
multi-track recorder, or as extra
instrument inputs, especially if your
MIDI keyboard or rack supplies a
pre-mixed stereo signal. Certain
stereo effects produce a perceived
imbalance between the left and right
channel levels. To correct for this you
will have to bring your stereo effect
back on a stereo channel, which has
a Balance control (11). When apply-
ing short left and right delays, the
shortest one will always seem
loudest. When pitch shifting up and
down in wide stereo to thicken a
sound, the signal shifted upwards will
seem louder than one that goes
down. In both cases use the Balance
control to compensate. When
performing any stereo imaging
exercise, dont just rely on the control
room monitors. Get a pair of
headphones and listen in stereo and
in reverse stereo, just in case you
have any significant hearing discrep-
ancies. Sometimes you might want
