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/or
external effects on channel. Adjust for desired
amount (use low settings for vocals, higher
settings for instruments).
HI FREQ EQ
Sets channel treble boost or cut for desired
tone shaping.
LO FREQ EQ
Sets channel bass boost or cut for desired
tone shaping.
AIB PAN
Used for stereo (left-right) positioning in stereo
sound reinforcement or recording. Position
straight up for center (monophonic) sound
reinforcement use.
INPUT CLlP
Indicates when input signal is too high. Adjust
INPUT
ATTEN until only occasional flashes are
noted.
INPUT ATTEN
Adjusts input attenuation for channel.
Suggested initial settings: condenser
microphones 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.
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
VOLUME,
EQualizers, EFFECTSIREVERB, or
NB PAN. 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
r
13 dB at 10 kHz on A and B
outputs and effects output; does not affect
monitor output.
LO FREQ EQ
Adjusts channel
r
13 dB at 100 Hz on A and B
outputs and effects output; does not affect
monitor output.
AIB PAN
Used for stereo positioning; allows
assignment of channel signal to both A and B
(straight up) or only A or B output channel (full
counterclockwise or clockwise), or any
position between.
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 A and
B
outputs plus A+B outputs
and
effectslreverb level; 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
Vdc simplex power supply voltage
activated by rear-panel switch.
