The Four-Channel Language Distribution System utilizes infrared transmission. The system is used in conjunction with Telecor Interpreter's Console to broadcast up to four translated languages. Receivers are used by the conference or audience members to select and listen to the language of their choice through headphones.
The system is comprised of two, dual-channel Modulators, providing four simultaneous channels, and two Emitter Panels. Additional Emitter Panels may be added to expand the area of coverage for large conference venues.
