DSSS Simultaneous Interpretation System TC-RF08F

GONSIN TC-RF08F digital interpretation system utilizes DSSS(direct sequence spread spetrum) to provide CD quality sound.

GONSIN TC-RF08F 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 8 audio channels, with working range of 50 to 200 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.

DSSS Receiver

The TC-RFJ08F receiver is designed to be used for 8 audio channels, and each channel utilizes DSSS with a unique spreading code, offering CD-quality sound.  The unit is powered by a rechargeable Lithium-ion battery pack.  The selected channel number, battery level and RF signal strength are shown on LCD screen Equipped with individual wireless RF receivers, participants 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.  Any number of receivers can be used within the effective working range. 

This receiver unit comes with a channel ID number selector, which is designed to avoid interference when multiple GONSIN DSSS systems are used at the same venue or building.
