Description

This system features the NEW WIR TX75 infrared transmitter, ensuring participants in a conference room, courtroom, classroom or other mid-sized venue receive direct, clear communication of your message without sacrificing security. Includes WIR RX22-4 receivers–ideal for single-or two-channel applications. The sleek and stylish TX75 is designed to maximize coverage area up to 5,000 square feet in single-channel mode. Two additional slaves (sold separately) can be added for additional coverage of up to 5,000 square feet each (for total coverage of up to 15,000 square feet). Placing additional slaves in the same room increases coverage and enhances freedom of movement. A single CAT-5 cable carries both power and signal to slaves–truly a one-cable connection. Mounting bracket and power supply are included.

Available options:

WIR TX7522-01 - Euro power cord

WIR TX7522-02 - UK power cord

WIR TX7522-04 - Australia power cord

Features

Green power–if no audio is present after a few minutes, unit automatically disables power to IR diodes, reducing power consumption by 80 percent.
Headset and stethoset receivers also available for use with WIR SYS 7522 (sold separately).
Robust digital communication bus between master and slave unit reduces interference.
Master unit has troubleshooting lights built in to simplify installation.
Separate RCA audio inputs for each channel (2.3/2.8 MHz) accept balanced or unbalanced line level inputs; use together for stereo operation or separately for mono.
Unit senses if only one channel is in use and doubles the output power on that channel for twice the coverage.
TX75-S slave emitter available for use with WIR SYS 7522 (sold separately).
Front cover can be painted to match decor.
