Infrared Language Distribution System (Model Number TC-902L/904L/906L )
IR Transmitter
The TC-Z902V/Z904V/Z906V infrared transmitter is a microprocessor based central unit which is designed to modulate and transmit 2,4 or 6 sound channels to different carrier frequencies. It features independent channel volume control, independent channel output level indicators, and independent channel audio output for sound recording. Test mode produces a different frequency tone for each input/channel. Two BNC sockets can link up infrared radiators in two lines. Multiple interpreter consoles can be connected to the transmitter in a daisy chain.

IR Radiator
The TC-H15 high-power infrared radiator can be switchable to 50% low power, making it suitable for use in larger halls and smaller rooms. The radiators integrated power supply unit is automatically switched on and off by the carrier signals from the transmitter by means of an high frequency sensor. The radiator is equipped with automatic gain control to ensure the infrared diodes function with maximum efficiency, and is naturally convection cooled for totally silent and maintenance-free continuous operation. It can be ceiling or wall mounted for permanent installation, or set up on an optional tripod for portable application.Multiple radiators can easily be daisy-chained together to expand coverage. The unit is easy to maintain and clean, with IR emitting diodes protected by the cover plate.

IR Receiver
The portable TC-J902L/J904L/J906L infrared receiver is designed to receive 2, 4 or 6 audio channels. The optical lens offers a wider receiving angle to pick up the infrared light signal. The delegate may listen to any selected language on a headphone/earphone. Volume level can be adjusted through the volume control for comfortable listening. Any number of receivers can be used within the radiator's effective coverage range.
