a. AUX Sends/Returns Function and Operation
(11) STEREO AUX RETURNS (LEFT/MONO, RIGHT)
(19) AUX 1,2 RETURN CONTROLS
The AUX Return jacks are the mono or stereo returns for
AUX 1 and 2. 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 respective Aux Return Control (19) and
then mixed into the left and right Master Mix Stereo Outputs
(30). 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 Return level controls (19) and mixed into
the left and right Stereo (30), while maintaining stereo sepa-
ration.
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 sig-
nal. 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 (16). 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 con-
trol 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.
CONTROLS AND CONNECTIONS

(12) AUX SENDS
The Aux Send 1 and 2 jacks are the outputs for the signals
sent from the channel Aux controls (6). The Aux Sends and
Aux Returns are all 1/4" unbalanced phone jacks wired: Tip =
positive (+), Sleeve = ground. AUX 1 is pre-fader and AUX 2
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. Master Aux Send levels are
adjusted by the Aux Send controls (19).
b. Main Mix Function and Operation
(30) STEREO OUTPUTS
(13) TAPE INPUTS
(14) REC OUTPUTS
(28) MASTER MIX FADER
(27) LED OUTPUT METER
(21) TAPE/REC TO MASTER SWITCH
The Stereo Outputs consist of both Left (L) and Right (R) bal-
anced XLR’s, wired: pin 1 = ground, pin 2 = hot (+), pin 3 =
cold (-), and unbalanced 1/4" phone jacks, wired: Tip = posi-
tive (+), Sleeve = ground.
The REC Outputs (14) also provide an output of the Master
Mix. These outputs are RCA jacks, and designed primarily for
inputs to tape recorders, etc. The output level routed to the
Stereo Outputs and REC Outputs is determined ultimately by
the setting of the Master Mix fader (28). The Master Mix
(signal on the master bus) is the sum of the signals routed
from all the channels and also the inputs from the AUX return
bus and the TAPE Input (13). Use the Tape/Rec to Master
switch (21) to route signals from the Tape Input (13) to the
Master Mix Fader (28). The level of signal routed to the
Master Mix fader (28) from DAT, tape decks, CD players,
