2. MASTER SECTION
a. AUX Send/Return Function and Operation
(13) AUX RETURN
(31) AUX RETURN CONTROL
The Aux Return jack enables a convenient input to the left
and right Master Mix busses. If you connect a signal to the
Return jack, the Aux Return will operate in mono and the sig-
nal will be routed to the Aux Return Control (31) and then
mixed into the left and right Master Mix bus. The Aux Return
is multi-functional. It may be used for returning the outputs of
effect units such as Tape Returns from a multi-track recorder,
or as extra instrument inputs such as from a MIDI keyboard.
(12) AUX SEND
(30) MASTER AUX SEND CONTROL
The Aux Send jack is the unbalanced output for the signals
from the Aux bus. It is pre-fader. This signal can be sent to
the input of an effects processor, multi-track recorder, or used
for any other line-level auxiliary purpose, such as monitor
feeds. The Aux Send level is adjusted by the channel Aux
Send controls (7) and the Master Aux Send control (30).
When the Aux/Mon switch (26) is in the depressed IN posi-
tion, the Aux send also functions as the mono output of the
Master Right Channel bus. (See also Master Mix Function
and Operation below)
b. Master Mix Function and Operation
(42) MAIN SPEAKER OUTPUTS
(16) TAPE INPUTS
(29) TAPE IN LEVEL CONTROL
(17) REC OUTPUTS
(27A,27B) STEREO MASTER MIX FADERS
(19) LED OUTPUT METER DISPLAY
(22) 7 BAND MASTER MIX GRAPHIC EQUALIZER
(25) EQ BYPASS SWITCH
(26) AUX/MON SELECT SWITCH
(14) STEREO MASTER INSERTS-PRE EQ
(15) STEREO MASTER INSERTS-POST EQ
The final Master Mix is output directly to the Main Speaker
outputs (42). These L/R outputs provide 200W at 4 ohms for
powering P.A. speakers rated for this power or more. Channel
A and B parallel outputs allow multiple speaker setups. You
can also access this Master Mix by utilizing the send function
of the Stereo Master Inserts (see below). The Record Out
(17) jacks output the Master Mix post-Stereo Master faders
(27A, 27B) and are pre-Master EQ (22) and pre-Stereo
Master Inserts (14,15). These outputs are RCA jacks, and
designed primarily for inputs to tape recorders, etc.
The output level routed to the Speaker outputs and REC out-
puts is determined ultimately by the setting of the Stereo
Master faders (27A, 27B). The Master Mix (signal on the
L/R main busses) is the sum of the signals routed from all the
channels and also the inputs from the EFFECTS and AUX
busses and the TAPE Input (16). The level input from the
Tape In (16) is adjusted with the Tape In Level control (29).
The level of signal routed to the Stereo Master faders
(27A,27B) from DAT, tape decks, CD players, etc., input to
the Tape Input (16) is determined by the setting of the output
volume control of the audio device being connected and the
Tape In Level Control (29), so care must be taken in adjust-
ing these levels so as to achieve proper balance in the final
mix and to prevent overload distortion. The 10-stage LED
Output Meter (19) can be used to maintain proper levels in
the master mix.
