SYSTEM

OVERVIEW

The Williams Sound WIR TX850 System consists of a MOD 111 Modulator and one or more

TX8 Emitters (also called emitters) which use invisible infrared (IR) light waves to broadcast

speech or music to wireless infrared receivers.

The MOD 111 accepts a variety of audio inputs and sends either a 95 kHz or 250 kHz

frequency modulated signal to the TX8 Emitter via coaxial cable. The emitter emits invisible

infrared light into the listening area. Infrared receivers detect the transmission and convert

the light signals back into audio signals.

The system is designed to transmit high quality audio for hearing assistance and language

translation applications. Because the system uses infrared light for transmission, it is not

affected by interference from radio equipment and does not interfere with radio equipment.

No FCC license is required. A single TX8 Emitter will cover up to 10,000 square feet of

listening area. Larger areas can be covered with additional emitters.

The system can be used with a microphone as a stand-alone system, or can be connected to

an existing sound system. Infrared Systems cannot be used in bright sunlight because of

sunlight’s large amount of interfering infrared light.
