GONSIN TC-RF16 DSSS simultaneous interpretation system utilizes the worldwide license-free 2.4GHz ISM frequency band and the state-of-the-art Direct Sequence Spread Spectrum (DSSS) technology to deliver CD qualitysound, provide excellent immunity from both noise and interference, and insure high security against unauthorized listening.

The system is designed to offer distortion-free wireless communication for simultaneous interpretation and language distribution in 16 channels, with operating range of 50 to 200 meters, ideally suited for use in business and government conferences, international conventions and other multilingual applications indoor and outdoor. TC-RFZ04 Control Unit The microprocessor based TC-RFZ04 digital control unit is able to transmit 4 audio channels, featuring independent channel level control, channel output level indicators, and channel signal outputs for sound recording. Via a DB25 cable, multiple interpreter consoles can be connected to the control unit in a daisy-chain. 4 control units can be cascaded together to form a 16-channel system.

The unit is powered by a rechargeable Lithium-ion battery pack. The selected channel number, battery level and RF signal strength are displayed on LCD screen. Equipped with an individual RF receiver, a participant can listen to any selected language channel on a personal earphone, monitor the battery status, check whether or not the unit is receiving the signal properly,and adjust volume level for comfortable listening. The floor language is heard when the interpreter turns offthe microphone . Any number of receivers can be used within the effective working range.
