WIR TX75-S Infrared Emitter Quick Setup Guide
Determine Transmitter and emitter
Determine the best location where the TX75 or TX75b 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. 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 RCA CH1,
CH2 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: Point the transmitter (TX-75) and emitter (TX75-S) towards the
listening audience.
Remember: Most objects block infrared light. The transmitter and emitter 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 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.
