Multi–Channel Infrared System Specifications

Two–Channel Infrared Modulator, Model MOD 112

Dimensions, Weight: 8.45" (21.5 cm) W x 8.18" (20.8 cm) D x 1.72" (4.4 cm) H, 3 lbs. (1.5 kg)

Color: Black epoxy paint with white legends

Rack Mount: One IEC rack space high, one or two units can be mounted in a single rack space with

optional RPK 005 (single) or RPK 006 (double) Rack Mount Kits

Power: External power supply, 24VAC, 50 or 60Hz, 10 VA maximum

Baseband Output: 50 Ω source impedance

Carriers: 100 mV per carrier

Channel 1: 95 kHz ± 50 kHz deviation, 50 µsec pre-emphasis

Channel 2:

250 kHz ± 50 kHz deviation, 50 µsec pre-emphasis

AGC: Variable slope compressor or soft limiter, switch selected

Carrier Timers: One 30 minute (approx.) timer per channel. Turns off carrier if channel is silent (lowest

light on bar graph does not light) for full 30 minutes.

Operating Req.: 0-50°C ambient temperature, non-condensing, non-corrosive atmosphere

Front Panel:

Power Switch: Two-position rocker, ON/OFF

Power Indicator: Green LED

Audio Level Controls: 1 control per channel

Audio Indicators: One (1) 10 LED bar graph per channel

Carrier LEDs: 1 carrier on indicator LED per channel, green

Limit/Compress Switch: Selects variable slope compression or soft limiting

Stereo/Discrete Switch: Selects stereo (coupled processing and timers, stereo monitoring)

or discrete (Independent processing and timers, mono monitoring)

Phones Switch: Selects CH 1 or CH 2 for phones when mode is in discrete position

Phones Output: 1/4" stereo phones jack. Produces stereo or mono output depending on mode selected.

Accepts stereo or mono phones. Any impedance

Infrared Test LED: IR LED for receiver testing, monitoring, and audio signal testing.

Effective to about 2 feet from front panel

Rear Panel:

Balanced (Floating) Line Input: 1/4" TRS jack. Accepts unbalanced or balanced line level inputs

Mic Input: lo-Z, 100 µV min. to 90 mV max. 1 mV nominal, 3 kΩ input impedance

Supplies simplex power 20 V (DIN45296) for condenser mics

Baseband Output:

(1) BNC connector, 50 Ω, 100 mV RMS per carrier, use RG-58 cable

Baseband Loopthru Input: (1) BNC connector, 50 Ω

Power Connections: 3-pin molex

Emitter Type: For use with Williams Sound Linear Emitters. For multi-emitter systems, each emitter

epeats the baseband signal to drive the next emitter in the chain.

Accessory Connector: 9-pin, Sub–D female, various circuit connections

(See diagram on top panel for details)
