IR Interpretation System Installation for International Summit

Hi,

We are organizing an international summit next month with delegates from 20+ countries. We need a Full Digital 64 Channels Interpreter Desk for simultaneous interpretation.

Our planned setup includes:

VIS-VLI700A Series Digital Infrared Transmitter

Two Digital Infrared Radiator Unit for large hall coverage

64 sets of VIS-VLI703A Series Digital Infrared Receivers

Headphone for Interpreters and Headphone for Delegates

Charger and Storage box for Infrared Receiver

Questions:

How should the infrared radiator units be positioned in a round-table conference room?

Is there a cable specification document for connecting the interpreter desk to the transmitter?

Can one transmitter support all 64 channels?

Thanks for your help!

    Great setup for an international summit. Here are the answers:

    Radiator positioning — mount the Digital Infrared Radiator Units high on the walls (or ceiling) and aim them at the delegates. Infrared is optical, so it needs clear line of sight — avoid columns, partitions or anything blocking the signal to the receivers. In a round-table room, two radiators placed on opposite walls, pointing inward, usually give even coverage.

    Cable spec — the interpreter desk connects to the transmitter with the digital conference cable (CAT5e/CAT6), and the transmitter links to the radiators with the supplied coaxial/BNC cabling. VISSONIC provides the wiring details for your exact models.

    Channel count — yes, one VIS-VLI700A transmitter carries the full 64 channels; the channel limit is set by the interpreter desk and receivers, not the transmitter.
