Detailed Product Description
Detailed Description
GONSIN TC-904 IR language distribution system is designed to offer 4-channel audio distribution using the advanced infrared transmission technology.
As the central element of the system, the infrared transmitter interfaces with 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 headphones.
The system operates in the higher 2 to 6 MHz frequency band which is immune to distortion from hall lighting andfree from radio frequency interference, ideally suited for use in business and government conferences, international conventions and other multilingual applications.
TC-Z904V
IR Transmitter
The TC-Z904V infrared transmitter is amicroprocessor based central unit which is designed to modulate and transmit 4 audio channels to different carrier frequencies. It features independent channel level control, independent channel output level indicators, and independent channel audio output sockets 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. A transmitter can connect multiple interpreter consoles in a daisy chain.

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