The original (OR) and a maximum of 7 target languages can simultaneously be transmitted on different carrier frequencies by narrow band frequency modulation. The transmitted signals are received by the SIR 320 receiver and can then be monitored with headphones. With miniature switches on the front panel the frequency band can be chosen and the channels can be switched ON or OFF. With a rotating switch it is possible to assign up to 32 transmission channels. 3 infrared transmitter diodes allow monitoring for the technician without radiators. Eight green LEDs indicate the status of the appropriate interpreter channel. LEDs on the front panel indicate the operation mode: channel ON (red) and audio signal available (green).
