Basically . . .
MONITOR
Independently controls channel monitor level
to monitor output. Adjust for desired monitor
mix when using a monitor system.
EFFECTSIREVERB
Controls amount of reverberation and lor
external effects on channel. Adjust for des~red
amount (use low settings for vocals, higher
settings for instruments).
HI FREQ EQ
Sets channel treble boost or cut for desired
tone
shap~ng.
LO FREQ EQ
Sets channel bass boost or cut for desired
tone shaping.
INPUT CLlP
Indicateswhen Input signal istoo high. Adjust
INPUT
ATTEN until only occasional flashes are
noted.
INPUT ATTEN
Adjusts input attenuation for channel.
Suggested
init~al sett~ngs: condenser micro-
phones or amplified instruments -12 to -30;
normal vocals
-6 to -12; loud vocals -12 to
-24; distant
miking 0.
VOLUME
Allows individual setting of channel input for
desired signal mix. If setting is consistently
low (1 or
2), or high (8 to lo), adjust INPUT
ATTEN.
Inputs:
Both inputs may be used at the same time with
similar microphones (one high and one low
impedance), allowing up to 12 microphones
simultaneously.
HI IMP
Provides for connection of high-impedance
microphones, direct instrument pickups,
keyboards, amplified instruments, tape
recorders or other high-level sources to
channel input.
BAL LO IMP
Provides for connection of low-impedance
dynamic, ribbon or condenser microphones
and other low-level inputs to channel input.
(Don't use when high-level source is used on
HI IMP input.)

MONITOR
Control precedes VOLUME ("pre-fader") and
other channel controls; not affected by VOL-
UME,
EQualizers, or EFFECTSIREVERB. Only
affected by INPUT
ATTEN, allowing totally
independent monitor
mix.
EFFECTSIREVERB
This channel send control follows the INPUT
ATTEN, VOLUME and EQ controls. Can be
used simultaneously with reverb and external
effects devices, or as a second monitor
("post-fader") to the EFFECTS OUTPUT jack
HI FREQ EQ
Adjusts channel 213 dB at 10 kHz on all out-
puts except monitor; does not affect monitor
output.
LO FREQ EQ
Adjusts channel 2 13 dB at 100 Hz on all out-
puts except
monltor; does not affect monitor
output
INPUT CLlP
Lights approximately 3 dB prior to clipping
of preamp or input channel equalizer. For
optimum signal-to-noise ratio, adjust INPUT
ATTEN for occasional flashes (no light may
mean noisy operation; constant light means
distortion).
INPUT ATTEN
Adjusts gain of preamplifier to permit channel
to accept microphone level signals, direct
instrument pickups, or high level aux signals
from amplified instruments or tape recorders;
almost any input device can be
accommodated.
VOLUME
Affects all outputs except monitor; does not
affect monitor mix.
HI IMP
Can be used with line matching transformer
(Shure
A95FP) to allow two low-impedance
microphones on channel (not recommended
for two condenser microphones).
BAL LO IMP
Also may be used to power most condenser
microphones such as the Shure
SM81; built-in
+24
~dc simplex power supply voltage
activated by rear-panel switch.
