Infra-red transmitter is a unit of our magical simultaneous translation equipment system (interpretation equipment); unit IR Transmission main unit-SI-H7106. The SI-H7106 Digital Transmitter is the central modulator unit in the digital infrared system. It accepts audio from the SI-H7106or other compatible audio sources. The SI-H7106 modulates the incoming audio signals onto carrier waves, which are sent directly to one or more SI-T7206 Digital Infrared Radiators. The output from the radiator is then passed on to each SI-R7406 delegate receiver.
