from radio equipment and does not interfere with

radio equipment. No FCC license is required.

A single TX6 Transmitter will cover up to 10,000

square feet of listening area in single channel mode

and 5,000 square feet in two channel mode. Larger

areas can be covered with additional transmitters.

The transmission is confined within opaque walls,

making it especially appropriate for applications in

which security is an issue, such as courtrooms and

corporate boardrooms. The Williams Sound Infrared

System is also commonly used where multiple sys-

tems are needed in adjacent rooms, such as movie

theaters and conference centers, without “spillover”

from adjacent rooms.

The system can be used with a microphone as a

stand-alone system, or it can be connected to an

existing sound system. Infrared Systems cannot be

used in bright sunlight, which contains large

amounts of interfering infrared light.

System Overview

The Williams Sound Two–Channel Infrared System,

Model TX600 consists of a MOD 112 Modulator

and one or more TX6 Transmitters (also called emit-

ters) which use invisible infrared (IR) light waves to

broadcast speech or music to wireless infrared

receivers.

The MOD 112 accepts a variety of audio inputs and

sends 95 kHz and 250 kHz frequency modulated

signals to the TX6 Transmitter via a coaxial cable.

The transmitter emits invisible infrared light into the

listening area. Infrared receivers detect the transmis-

sion 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
