WIR SYS 7518 PRO - Overview

The WIR SYS 7518 PRO from WILLIAMSAV is a sleek, mid-range infrared system. Featuring a professional design that complements your room's aesthetics, the WIR SYS 7518 PRO also utilizes green power; if no audio is present after a few minutes, the unit automatically disables power to IR diodes. You can reduce overall power consumption by 80 percent.

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.

  • Features:

    • Front cover can be painted to match décor
    • Robust digital communication bus between master and slave unit reduces interference.
    • Master unit has troubleshooting lights built in to simplify installation.
    • Separate Phoenix Contact Connector audio inputs for each channel accept balanced or unbalanced line level inputs; use together for stereo operation or separately for mono.
    • Unit senses if only one channel is in use and doubles the output power on that channel for twice the coverage.
    • Additional TX75-S slave emitter is available for use with the WIR SYS TX7518 PRO (sold separately).
    • Headset and body-pack receivers also available for use with WIR SYS TX7518 PRO (sold separately).
