WIR TX75 C/D Infrared Transmitter
Quick Setup Guide
Determine Transmitter placement
Determine the best location where the WIR TX75 C or WIR TX75 D will
cover the desired area. Remember, IR signals need a clear line of sight to
the receiver for optimum reception. It is usually better to have the transmitter
located above the height of the receiver users.
The transmitter can be mounted on the wall or ceiling with the included
mounting bracket. An optional microphone adapter is available for mounting
to microphone stands. The threaded connector on the top and bottom of the
transmitter is standard to most camera tripods.
Plug the power supply into the transmitter. Make sure the green power LED
is on. Install the audio input cord of your choice and apply signal to the

transmitter input 1, 2 or both. The audio level indicator should be blinking at
peak audio levels. Be sure that the receivers are set to the same channel/
frequency used on the transmitter.
Important: Remember to point the transmitter towards the listening
audience.
Remember: Most objects block infrared light. The transmitter cannot be
concealed behind walls, glass, curtains, etc.
Optional WIR TX75-S emitter for Additional Coverage
For larger facilities, additional emitters can be used to increase the total
coverage area. The WIR TX75 C/D is capable of driving two WIR TX75-S slave
emitters. Power, baseband and digital data bus are fed via CAT-5e cable to
each TX75-S slave.
