WIR SYS 7522 PRO

Mid-range Infrared System

Product Highlights

  • Designed to maximize coverage area up to 12,000 sq. ft.
  • Meets ADA accessibility guidelines
  • Sleek, professional styling complements room aesthetics. 
  • Unit senses if only one channel is in use and doubles the output power on that channel for twice the coverage.

Description

This 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. Includes WIR RX22-4 receivers–ideal for single-or two-channel applications. The sleek and stylish WIR 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. Mounting bracket and power supply are included.
