The Williams Sound WIR TX75c infrared transmitter ensures participants in your conference room, courtroom, classroom or other mid-sized venue receive direct, clear communication of your message without sacrificing security. The sleek and stylish TX75 is designed to maximize coverage area up to 5,000 square feet in single-channel mode when using the RX22-4 receiver. Two slaves (WIR TX75-S) can be added for additional coverage up to 5,000 square feet each (15,000 sq. ft. total), when mounted up to 100 feet from the master transmitter. 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. Operates on the 2.3 / 2.8 MHz bandwidth. Mounting bracket and international power supply are included.
