The SI-H7104 Digital Transmitter is the central modulator unit in the digital infrared system. It accepts audio from the SI-H7104 or other compatible audio sources. The SI-H7104 modulates the incoming audio signals onto carrier waves, which are sent directly to one or more SI-T7204 Digital Infrared Radiators. The output from the radiator is then passed on to each SI-R7404 delegate receiver.
