3. MASTER SECTION
a. AUX Sends/Returns Function and Operation
(9) STEREO AUX RETURNS (LEFT/MONO, RIGHT)
(18) AUX RETURN CONTROL
The Aux Return jacks are the mono or stereo returns for Aux
Send. 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 (18) and then mixed into the left and
right Master Mix Stereo Outputs (11). The separate left and right
return jacks are provided 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 (18)
and mixed into the left and right Stereo Out (11), while
maintaining stereo separation.
The Aux Returns are multi-functional. They may be used for
returning the outputs of effect units, 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 (14). When applying 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, don’t 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
discrepancies. Sometimes you might want to narrow the stereo
width of a reverb field. To do this you will have to come back on
two mono channels to get independent pan for the left and right
signals.
(10) AUX SEND
The Aux Send jack is the output for the signal sent from the
channel AUX/EFF controls (5). They are 1/4" unbalanced phone
jacks wired: Tip = positive (+), Sleeve = ground. Aux Send is
post-fader. These signals can be sent to the input of an effects
processor, multi-track recorder, or used for any other line-level
auxiliary purpose
b. Main Mix Function and Operation
(11) STEREO OUTPUTS
(15) TAPE INPUTS
(16) REC OUTPUTS
(29) MASTER MIX GAIN CONTROL
(21) LED OUTPUT METER
(24) TAPE/REC TO MASTER SWITCH
The Stereo Outputs are Left (L) and Right (R) unbalanced 1/4"
phone jacks, wired: Tip = positive (+), Sleeve = ground. The REC
Outputs (16) also provide an output of the Master Mix. These
outputs are RCA jacks, and designed primarily for inputs to tape
recorders, etc.
