Page 3: System Overview
YSTEM VERVIEW The Williams Sound SoundPlus Infrared Listening System consists of a MOD 232 Modulator(s) and ™ one or more TX9 Emitters which use invisible infrared (IR) light to broadcast speech or music to wireless infrared receivers. The system is designed to transmit high quality audio for hearing assistance and language translation applications. -
Page 4: Mod 232 Modulator Setup
MOD 232 M ODULATOR ETUP The modulator is usually located with the sound system amplifier or mixer for easy access to an audio ETERMINE OCATION input signal. For portable systems, the modulator can be placed near the emitter or in another convenient location. - Page 5 The MOD 232 can directly drive one or two emitters. TX9 emitters repeat the baseband signal, so any ASEBAND ABLE ONNECTION number of emitters can be used. The modulator outputs CANNOT be split with CATV splitters. Determine the length of RG-58 cable needed to reach from the TX9 Emitter to the Modulator unit. Install BNC connectors to each end of the cable.

TX9 E MITTER ETUP TX9 L OCATION AND LACEMENT To determine the best location for the TX9 Emitter, it helps to think of the IR emitter as an invisible floodlight. You’ll want to aim it so the listeners are “flooded” with the infrared light. Mount the emitter at least 2 ft (.61 m) above the audience. -

The infrared radiation does not drop to zero outside the illustrated patterns; it decreases. It still may be useable at a greater distance, depending on the receiver sensitivity and the reflective characteristics of the room. - Page 10 ULTIPLE MITTERS NSTALLED TO AXIMIZE OVERAGE Figure 12A Figure 12A and !2B: Overlapping Illumination Patterns to Cover Larger Listening Areas Figure 12B Figure 13: Connecting Multiple TX9 Emitters An unlimited number of WIR TX9 emitters can be daisy-chained together to maximize the coverage area.

If the signal sounds okay, you may need to re-position the emitter panels or add additional panels. NOTE: Make sure the powerline voltage does not fall below 94V, or system performance will be greatly reduced! Check for ground loops or noise on the input signal.
