SINGDEN Digital audio wireless conference system simultaneous interpretation equipment

SINGDEN Digital audio wireless conference system simultaneous interpretation equipment
project case:           Transmission main unit              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.   Features:    •  High security, prevent external interference.    •  Suitable for different conference hall    •  Automatic level control function (ALC).    •  No disturb under daylight lamp    •  Easy to operate and save in project cost    •  With the most advanced technology    •  Elegant configuration in accordance to ergonom    •  Input channel direct function    •  Has 4CH interpreter’s voice for record    •  PB test and display function    •  Installed in a 19-inch frame    Technical Specifications:
