The microprocessor based TC-Z906 infrared transmitter is able to modulate and transmit 6 sound channels to different carrier frequencies.

It features built-in IR test diodes for audio monitoring and testing of receivers, built-in automatic level control (ALC) to ensure comfortable listening levels, independent channel level control, independent channel output level LED indicators, and independent channel audio output sockets for sound recording.

Test mode produces a different frequency tone for each input/channel. Up to five interpreter consoles can be connected to the transmitter in one single daisy chain. Infrared radiators can be linked up in two lines via two BNC sockets on the rear panel.
