Williams Sound WIR TX75 D IR Transmitter/Modulator
The WIR TX75 D 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 D 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 coverageup to 12,000 square feet each (36,000 sq. ft. total), when mounted up to100 feet from the master transmitter. Placing additional slaves in the sameroom 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 new series has Phoenix Contact® input connectors and improved range.
*Operating range varies based on receiver used. See emitter specifications for coverage area by receiver type.
System includes:
- (1) WIR TX75 D Infrared Transmitter operating on 3.3/3.8 MHz
- (1) BKT 024 wall / ceiling mounting bracket
- (1) TFP 046 power supply
- (1) WLC 004 main power cord (U.S.)
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 by80 percent.
- WIR TX75 S slave emitter available (sold separately)
- Headset, stethoset and body-pack receivers available for use with WIR TX75 D (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 - 3.3/3.8 MHz accept balanced or unbalanced line level inputs; use together for stereo operationor 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

Each channel shall have an audio input level LED. There shall be a single 3.5mm microphone input with gain control.
- The mic input has a channel selector switch and switch to turn off all indicator LED’s.
- The transmitter has two RJ45 outputs supplying power and baseband signal to two WIR TX75-S slave emitters via CAT-5e cable. Each RJ45 output shall have a green and yellow LED signaling that the slave emitters are receiving power and baseband signal.
- A single CAT-5e cable supplies power, signal and digital control to the slave unit up to 100 ft from the transmitter.
- The transmitter is powered by a 48VDC universal power supply, 50-60Hz, 100-240 VAC input, 19.2W.
- The transmiiter is covered by a two-year parts and labor warranty, 90 days on accessories.
