"The DT 6008 Digital Transmitter is the central modulator unit which receives audio from the interpreter and transmits it for wireless digital language distribution.
The DT 60xx Digital Transmitter accepts audio from the AO 6004 or AO 6008 Audio Output Units or from CU 6105 or CU 6110 directly. Or other audio sources can be connected. The transmitter modulates these signals onto carrier waves. The digital carrier waves are transmitted directly to the RA 60xx Digital Radiators located in the room - for wireless distribution to the DR 60xx Digital Receivers."
