MODULES

Mic/Mono Line Input Module, I3800

GAIN
+/-20 dB fine gain adjustment on mic and line inputs.
PHANTOM ON/OFF
Switch for selecting 48 V phantom power.
PHASE (X / =)
Phase reversal switch.
MIC GAIN
10-50 dB gain on mic input.
HP
High pass filter, 12 dB/octave. 80 Hz and 140 Hz cut off
frequencies.
MIC / LINE
Mic/Line input selector. (Separate XLR-type connectors).
LOW
Parametric equalizer low end. +/-12 dB, 50 Hz to 1kHz peak/
dip. Q=1.3 at max peak/dip.
HIGH
Parametric equalizer high end, +/-12 dB, 600 Hz to 10 kHz
peak/dip. Q=1.3 at max peak/dip.
AUX 1-4
Aux output pre/post selectors and level pots. AUX 1 and
AUX 2 have center off switches and no pots. Post fader may
be taken before or after AB ON switch (jumper selectable).
PAN POT
Pan pot for panning signal between A and B outputs when
A/B ON switch is depressed.
S/NORM SWITCH
With this switch in the S position, a phase reversal of the
signal is sent to output B. This provides therefore the 'S' sig-
nal of an MS configuration on the AB outputs. The 'M' signal
would be fed from a separate mic channel (in NORM posi-
tion). In this way, two faders can be used for controlling an
MS signal. Note: The pan pot must be set centred for both
channels when used in MS configuration.
ON AIR LED
This is lit when the fader is open and the AB Switch is ON.
AB ON
Channel On switch. Affects stereo output only, leaving AUX
and PFL active.
PFL
Pre-fade listen, with LED. Jumper settings determine
whether PFL is cut when channel is On Air, or is independent
of On Air status.
PEAK
Overload LED.
