GONSIN TC-902/904/906 infrared system is designed to offer simultaneous interpretation and audio distribution for 2/4/6 different languages using the proven mature infrared light transmission technology.
Operating in the higher 2 to 6 MHz frequency band, the system is immune to distortion from hall lighting and free from radio interferences, ideally suited for use in business and government conferences, international conventions and other multilingual applications.
IR Transmitter
The TC-Z902V/Z904V/Z906V infrared transmitter is a microprocessor based central unit which is designed to modulate and transmit 2/4/6 sound channels to different carrier frequencies. It features built-in IR test diodes for audio monitoring and testing of receivers, independent channel volume control, independent channel output level indicators, and independent channel audio output for sound recording.

IR Radiator
The TC-H15/25 high-power infrared radiator can be switchable to 50% low power, making it suitable for use in larger halls and smaller rooms. The radiator's 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.

IR Receiver
The portable TC-J902L/J904L/J906L infrared receiver is designed to receive 2/4/6 audio channels. The unit is powered by a more environment-friendly rechargeable Lithium-ion battery pack. The selected channel number and battery level can be displayed on LCD screen. The user may listen to any selected language on a personal earphone. Volume level can be adjusted through a thumbwheel switch for comfortable listening. Any number of receivers can be used within the radiator's effective coverage range.
