3. MASTER SECTION
a. AUX Send/Return Function and Operation
(18) AUX RETURN
(29) 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 (29) 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.
(17) AUX SEND
(28) 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 (28).
b. Master Mix Function and Operation
(14) STEREO OUTPUTS
(15) TAPE INPUTS
(16) REC OUTPUTS
(27) TAPE IN LEVEL CONTROL
(25A, 25B) STEREO MASTER MIX FADERS
(19) LED OUTPUT METER DISPLAY
(24) 7 BAND MASTER MIX GRAPHIC EQUALIZER
The Stereo Outputs (14) consist of both Left (L) and Right
(R) balanced XLR’s, wired: pin 1 = ground, pin 2 = hot (+),
pin 3 = cold (-), and unbalanced 1/4” TRS phone jacks, wired:
Tip =signal, Ring open, Sleeve = ground. The Record Out
(16) jacks output the Master Mix post-Stereo Master faders
(25A, 25B) and are pre-Master EQ (24). These outputs are
RCA jacks, and designed primarily for inputs to tape
recorders, etc.
The output level routed to the Stereo Outputs and REC out-
puts is determined ultimately by the setting of the Stereo
Master faders (25A, 25B). The Master Mix (signal on the
main L/R 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 (15). The level input from the
Tape Input(15) is adjusted with the Tape In Level control
(27). The level of signal routed to the Stereo Master faders
(25A, 25B) from DAT, tape decks, CD players, etc., input to
the Tape Input (15) is determined by the setting of the output
volume control of the audio device being connected and the
Tape In Level Control (27), 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.
The MXE-1212 is equipped with a 7-band Stereo Graphic
Equalizer (24), allowing final tonal adjustments on the Master
Mix. This Master EQ is post-Stereo Master faders (25A,25B)
so you must exercise care in the proper use of these EQs for
best overall sound (see also MONO INPUT SECTION, (6) EQ
above).
