WIR SYS 7518 PRO

Mid-range Infrared System

Product Highlights

  • Designed to maximize coverage area up to 12,000 sq. ft.
  • Looks great! Sleek, professional styling complements room aesthetics.
  • Green power–if no audio is present after a few minutes, unit automatically disables power to IR diodes, reducing power consumption by 80 percent.

Description

The WIR TX75 PRO 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 PRO is designed to maximize coverage area up to 12,000 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 12,000 square feet each (36,000 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. Mounting bracket and international power supply are included.
