INDIVIDUAL INPUT CHANNEL CONTROLS
Additional information
MONITOR
Controls channel monitor send
independently of channel volume
control. Adjust for desired level
when using a monitor system, or
for
auxiliaryortape recording mix.
REVERB
Controls amount of reverberation
on channel (use low settings for
vocals, high settings for instru-
ments.)
EQUALIZATION
TREBLE
Inner concentric control sets
channel treble boost or cut for
desired tone shaping.
BASS
Outer concentric control sets
channel bass boost or cut for
desired tone shaping.
INPUT OVERLOAD INDICATOR
Lights when the input signal is
too high. Adjust
INPUTATTENU-
ATlON control until only
occa-
sional
flashes are noted on signal
peaks.
INPUT ATTENUATION
Adjusts input attenuation for each
channel. Suggested initial set-
tings: condenser microphones or
amplified instruments -1
2
to -30;
normal vocals or speech
-6
to
-1
2;
loud vocals
-1
2 to
-24;
distant mik-
ing
0.
VOLUME
Allows individual setting of chan-
nel input for desired signal mix. If
setting is consistently low (1 or 2)
or high
(8
to
lo),
check INPUT
ATTENUATION adjustment.
IMPORTANT: Set this Control
fully counterclockwise (off) when
channel is unused.
MONITOR
Control precedes VOLUME ("pre-
fader") and other channel controls
allowing independent monitor mix
affected only by INPUT ATTEN-
UATION.
REVERB
Control follows INPUT ATTENUA-
TION, EQ and VOLUME controls.
TREBLE
Adjusts channel k1O dB at
10
kHz;
does not affect MONITOR output.
BASS
Adjusts channel -+I0 dB at 100
Hz;
does not affect MONITOR
output.
INPUT OVERLOAD INDICATOR
Lights approximately
3
dB prior
to clipping of preamp or input
channel equalizer.
For optimum
signal-to-noise ratio, adjust INPUT
ATTENUATION for occasional
flashes
(no light may mean noisy
operation; constant light means
distortion.)
INPUT ATTENUATION
Attenuates input preamplifier gain
up to 30 dB to permit channel to
accept any signal level from mi-
crophones to direct instrument
pickups, or high level (aux) sig-
nals from amplified instruments
or tape recorders; almost any input
device can be accommodated.
(See rear panel Channel
1
&
2
AUX/MIC switches.)
VOLUME
Follows INPUT ATTENUATION
and EQUALIZATION controls;
does not affect channel MONI-
TOR level.
