DSSS Interpretation System TC-RF04/08/12/16



DSSS Interpretation System TC-RF04/08/12/16

The GONSIN TC-RF04/08/12/16 DSSS wireless interpretation system uses the 2.4GHz frequency band and state-of-the-art Direct Sequence Spread Spectrum (DSSS) technology to offer CD quality sound, excellent immunity from noise and interference, and high security against unauthorized listening.

The interpretation system is designed for simultaneous interpretation and language distribution in 4, 8, 12 or 16 channels. With an operating range of more than 100 meters, it is ideally suited for use in business and government conferences, international conventions and other indoor and outdoor multilingual applications.

 

TC-RFZ04 DSSS Control Unit/Transmitter

The microprocessor based TC-RFZ04 DSSS control unit is able to transmit 4 operating channels, having independent channel level controls, channel output level indicators, and channel signal outputs for sound recording. Via the DB25 cable, multiple interpreter consoles can be connected to the control unit in a daisy-chain. Four control units can be cascaded together to transmit up to 16 channels in one system.

TC-RFJ04F/08F/12F/16F DSSS Receiver

The portable DSSS receiver, as a part of our interpretation system, is designed to receive 4, 8, 12 or 16 channels with CD quality sound. The unit is powered by a rechargeable Lithium-ion battery pack. The selected channel number, battery level and signal strength are displayed on LCD screen.

When a participant is equipped with an individual DSSS receiver, he  can listen to any selected language channel on a personal headphone, monitor the battery status, check if the unit is receiving the signal properly, and adjust the volume level for comfortable listening. The floor language is heard when the interpreter turns off the microphone. Any number of receiver units can be used within the effective working range.

This receiver unit is equipped with a built-in DIP switch to set ID numbers to avoid interference when multiple GONSIN systems are used at the same venue or in the same building.
