10-channel digital DSSS 2.4 GHz simultaneous interpretation systems

TC-RF10 - 10-channel, 2.4 GHz DSSS simultaneous interpretation system

TC-RF1A-4 DSSS 4-channel digital transmitter The TC-RF10 digital DSSS simultaneous interpretation system transmits on the worldwide license-free 2.4 GHz frequency band and incorporates 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 10 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. This system is available in 2, 4, 6, 8, 10, 12 and 16 channels.

Interpreter Console

The TC-F16 interpreter console is a digitally-controlled workstation allowing two interpreters to work in turn.

Handles simultaneous interpretation for up to 16 different languages.

Gooseneck microphone and headset microphone can be used

Built-in loudspeaker with volume level control

LCD screen for specific information display

3.5mm jacks on both sides for MIC input and headphone/recording output

3 incoming languages can be preset, with pre-select A/B/C keys.

Automatic channel interlocking prevents interpreters from using same outgoing channel

Relay interpretation allows the interpreters to work from an active channel other than the floor

MUTE key to enable a brief muting of the microphone for cough cut

SLOW key to alert the current speaker to speak slowly

Loudspeaker is automatically switched off when MIC is on or headset is used

The floor signal automatically goes to the output channel after the microphone is turned off

Multiple interpreter consoles can be connected in a daisy-chain
