Details
The Williams Sound WIR SYS 7522 PRO mid-range infrared system features the WIR TX75 PRO 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. This system includes the WIR RX22-4 receivers which are ideal for single-or two-channel applications.
The sleek and stylish TX75 PRO is designed to maximize coverage area up to 12,000 square feet in single-channel mode. Two additional slaves (sold separately) can be added for additional coverage of up to 12,000 square feet each (for total coverage of up to 36,000 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. A mounting bracket and power supply are included.
