WIR TX75 C - Overview

The WIR TX75 C/D 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 C/D PRO is designed to maximize coverage area - now 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 power supply are included.

Note: This system is ordered as the WIR TX75 C (2.3,2.8 MHz) or the WIR TX75 D (3.3,3.8 MHz). "PRO" refers to this new series with Phoenix Contact connectors and improved range. PRO is not part of the model number.

*Operating range varies based on receiver used. See emitter specifications for coverage area by receiver type.

The TX75 can be mounted on any camera tripod stands with a 1/4" - 20 threaded connector.

  • Features:

    • Now features improved range - up to 12,000 sq. ft.*
    • Phoenix Contact connector audio inputs
    • Power-saving - if no audio is present after a few minutes, unit automatically disables power to IR diodes, reducing power consumption by 80 percent.
    • WIR TX75 S slave emitter available for use with WIR TX75 C or WIR TX75 D PRO (sold separately)
    • Headset, stethoset and body-pack receivers available for use with WIR TX75 C or WIR TX75 D PRO (sold separately).
    • Robust digital communication bus between master and slave units reduces interference.
    • Master unit has troubleshooting lights built in to simplify installation.
    • Separate phoenix audio inputs for each channel - 2.3/2.8 MHz (or 3.3/3.8 MHz) 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.
    • 5-year warranty
    • *Operating range varies based on receiver used. See emitter specifications for coverage area by receiver type.
