RF OUTPUTS
Page 2
7. RF OUTPUTS - Chassis mounted RF BNC jacks,
(3.5 mm). The RF jacks provide the frequency
modulated audio subcarrier signal which the
emitter panel(s) will convert into infrared light.
Modulated audio bandwidth is 30 Hz - 20 kHz.
8. CONTROL PORT - Female, 37-pin, standard D-
sub connector. Provides connections for
external control of Presets selection and preset
programming. Also provides tally connections
for all control functions.
9. PA-422 IN - Male, 9-pin D-sub connector. This
port connects to the PA-422 OUT of the MCS-
MCP Master Control Panel, an MCS-IB
Interface Box or other PA-422 control devices.
10. PA-422 OUT - Female, 9-pin D-sub connector. It
is used to carry the PA-422 data to the next PA-
422 device.
11. POWER CONNECTOR - Six-pin wago connector.
Requires +15 VDC and –15 VDC external
supply.
12. CHASSIS GROUND POST - A screw with a star
washer enables the installer to secure a ground
wire to the chassis.
1. POWER STATUS LED - Indicator for AC
Power On.
2. CARRIER FREQUENCY OPTIONS - Internal
jumpers provide a means to switch each
modulator between two frequency-modulated
subcarriers. Each modulator can be set to
either 95 kHz or 250 kHz.
3. CARRIER FREQUENCY INDICATOR - The
illuminated LED indicates the selected carrier
frequency.
4. INPUT GAIN TRIM POTS - Accessed through the
front panel with a small flat-blade
screwdriver, these trim pots adjust the input
gain +/- 15 dB, to compensate for varying
input signal levels.
5. PROGRAM INPUTS - Audio inputs, terminal
block connections with mating connector,
electronically balanced, accept balanced or
unbalanced signals from line-level devices.
Normal input level is +4 dBu with a maximum
input level of +24 dBu.
6. PROGRAM OUTPUTS - Audio outputs, terminal
block connections with mating connector.
Outputs are loop through from the inputs.
