Detailed Product Description

GONSIN TC-902 IR simultaneous interpretation system is designed to offer 2-channel language ditribution for simultaneous interpretation using the advanced infrared light transmission technology.   

As the central element of the system, the infrared transmitter interfaces with either analog or digital conference system, connects interpreter consoles and infrared radiators which transmit audio signals to wireless multi-channel receivers for the delegates to hear the language of their choice via personal earphones.

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 infrared transmitter is a microprocessor based central unit which is designed to modulate and transmit 2 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/TC-H25 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-J902 infrared receiver is designed to receive 2 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 radiators effective coverage range.
