GONSIN TC-904 infrared system is designed
to offer simultaneous interpretation and audio
distribution for 4 different languages
using the proven mature infrared light transmission
technology.
As the central element of the system,
the infrared transmitter interfaces with either
analog or digital conference system, connects
interpreter consoles and infrared radiators which
transmit audio signals to wireless multi-channel
receivers for the delegates to hear the language
of their choice via personal earphones.
Operating in the higher 2 to
6 MHz frequency band, the system is immune to
distortion from hall lighting and free from radio interferences, ideally
suited for use in business and government conferences,
international conventions and other multilingual
applications.

Gonsin Infrared Simultaneous Interpretation Manual - PDF
Interpreter
Console
The TC-F06 interpreter console is
a digitally-controlled workstation allowing two
interpreters to work in turn.
Handles simultaneous interpretation
for up to 6 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 switched off
Multiple interpreter consoles
can be connected in a daisy-chain
Designed to comply with all related
international standards & requirements.

IR Transmitter 
The TC-Z904V infrared
transmitter is a microprocessor based central
unit which is designed to modulate and transmit
4 sound channels to different carrier frequencies.
It features built-in IR test diodes for audio
monitoring and testing of receivers, independent
channel volume control, independent channel output
level indicators, and independent channel
audio output for sound recording. Test
mode produces a different frequency tone for each
input/channel. Two BNC sockets can link up infrared
radiators in two lines. Multiple interpreter consoles
can be connected to the transmitter in a daisy
chain.

IR Radiator
 The TC-H15 high-power infrared radiator
can be switchable to 50% low power, making it
suitable for use in larger halls and smaller rooms.
The radiator�s integrated power supply unit is
automatically switched on and off by the carrier
signals from the transmitter by means of an high
frequency sensor. The radiator is equipped with
automatic gain control to ensure the infrared
diodes function with maximum efficiency, and is
naturally convection cooled for totally silent
and maintenance-free continuous operation. It
can be ceiling or wall mounted for permanent installation,
or set up on an optional tripod for portable application.Multiple
radiators can easily be daisy-chained together
to expand coverage. The unit is easy to maintain
and clean, with IR emitting diodes protected by
the cover plate.

delegate may listen to any selected language on
a headphone/earphone. Volume level can be
adjusted through the volume control for comfortable
listening. Any number of receivers can be
used in an installation.
