GONSIN TC-RF04/08/12/16 digital DSSS simultaneous interpretation system utilizes worldwide unlicensed 2.4GHz frequency band and state-of-the-art Direct Sequence Spread Spectrum (DSSS) technology to deliver CD quality sound, provide excellent immunity from both noise and interference, and insure high security against unauthorized listening.
The system offers distortion-free wireless solution for simultaneous interpretation and language distribution in 4/8/12/16 audio channels, with working range of more than 100 meters, ideally suited for use in business and government conferences, international conventions and other multilingual applications.
DSSS Control Unit
The microprocessor based TC-RFZ04 control unit is able to transmit 4 audio channels, featuring independent channel level control, independent channel level indicators, and independent channel outputs for sound recording. Via a DB25 cable, multiple interpreter consoles can be connected to the control unit in a daisy-chain. Multiple control units can be cascaded together to form a system for 16 audio channels.
