WIR SYS 7518

Mid-range Infrared System

Product Highlights

  • Designed to maximize coverage area up to 4,000 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

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 comfortable, stethoset-style, WIR RX18 infrared receivers–ideal for single-or two-channel applications. The sleek and stylish TX75 is designed to maximize coverage area up to 4,000 square feet (transmitter with WIR TX75-S slave) in single-channel mode. One additional slave (sold separately) can be added for additional coverage of up to 2,000 square feet (for total coverage of up to 6,000 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 brackets and power supply are included.
