SYSTEM OVERVIEW

The WIR TX90 two channel infrared transmitter combines infrared modulator and emitter technology into a

single mountable enclosure - reducing operating cost and eliminating precious rack space.

The WIR TX90 features an easy to use configuration preset for Music, Voice, or Hearing Assistance

Applications. It operates on dual 2.3/2.8 or 3.3/3.8 MHz selectable frequencies - ideal for high quality audio

programs such as music, theater and audio description. The WIR TX90 will accept any line level, balanced or

unbalanced audio inputs, and includes adjustable tone and volume control. Infrared receivers detect the trans-

mission and convert the light signals back into audio signals. The 2.3-3.8 MHz operating frequencies mini-

mize high efficiency lighting interference.

No FCC license or radio approval is required with this equipment. It can be used anywhere in the world.

NOTE: This equipment has been tested and found to comply with the limits for a Class Adigital device, pur-

suant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful

interference when the equipment is operated in a commercial environment. This equipment generates, uses,

and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manu-

al, may cause harmful interference to radio communications. Operation of this equipment in a residential area

is likely to cause harmful interference in which case the user will be required to correct the interference at his

own expense.

NOTICE: A PLASMA MONITOR CAN DEGRADE THE AUDIO QUALITY OF THE WIR TX90

TRANSMITTER. FOR BEST PERFORMANCE, THE TRANSMITTER SHOULD BE POSITIONED

AS FAR AWAY FROM THE PLASMA MONITOR AS POSSIBLE.
