TC-Z906 infrared transmitter
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.
