GONSIN TC-RF02/04/06/08/10/12/16 digital DSSS simultaneous interpretation system utilizes worldwide unlicensed 2.4GHz frequency band and incorporates state-of-the-art Direct Sequence Spread Spectrum (DSSS) modulation technology to deliver crystal clear CD quality sound, provide excellent immunity from both noise and interference, and insure high security against tapping or eavesdropping.

The system offers distortion-free wireless solution for simultaneous interpretation and language distribution in 2/4/6/8/10/12/16 audio channels, with working range up to 300 feet indoor and 1100 feet outdoor, ideally suited for use in business and government conferences, international conventions and other multilingual applications

Digital Control Unit

The microprocessor based TC-RFZ02/TC-RFZ04 digital control unit is able to transmit 2 or 4 signal channels, featuring built-in automatic level control (ALC) to ensure comfortable listening levels, independent channel level control, independent channel output level indicators, and independent channel signal outputs for sound recording. Via a DB25 cable, multiple interpreter consoles can be connected to the control unit in a daisy-chain, and multiple control units can be cascaded together to transmit up to 16 signal channels in a system.

RF Antenna Unit

The TC-RFF01/02 high-gain directional antenna is designed for 1 or 2 operating channels, suitable for both indoor and outdoor applications. The digital control unit provides the DC power to the antenna via the SYV 50-7 coaxial cable with N-type connector. Since radio signals pass through walls and ceilings, the antenna unit may be positioned centrally in the conference venue or even in the control room. The unit can be mounted on wall, ceiling or tripod stand.

Digital RF Receiver

The portable TC-RFJ02/04/06/08/10/12/16 digital RF receiver is designed to be used for up to 2/4/6/8/10/12/16 audio channels, offering crystal-clear reception and CD-quality sound with sampling rate at 44.1kHz. The unit is powered by a more environment-friendly rechargeable Lithium-ion battery. 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 in an installation.

The RF receivers are protected against interference from other mobile equipment. The digital encryption of the transmitted data ensures high security against unauthorized listening. Only those receivers that have the correct digital encryption key are allowed to receive and decode the transmitted signals. Non-authorized receivers will only be able to detect a noise signal.

Interpreter Console

The TC-F902/904/906/908/910/912/916 interpreter console is a digitally-controlled workstation for two interpreters to work in turn. Interpreters may quickly switch between the floor language and the channel set. An automatic channel interlocking function prevents them from using the same output channel. The auto relay function enables them to work from an active channel other than the floor, and to provide relay interpretation in case they are unfamiliar with the floor language and unable to interpret it. Pressing the COUGH CUT button enables a brief muting of the microphone. Automatic acoustic feedback prevention is ensured when the interpreters listen to their own interpretation. Multile consoles can be daisy-chained to the RF control unit which is preset as the master control unit.
