Overview
The Compact Transmitter MSI8V is used within the CDSVAN Conference System for transmission of 8 audio
channels by infrared light.
System function
The audio signals are converted into frequency modulated infrared light and then transmitted by means of
INFRACOM Radiators HLN82, which are directly connected to the MSI8V. The original (OR) and up to 7 other
languages can be simultaneously transmitted on different carrier frequencies by narrowband frequency modulation.
Infrared radiators transmit the information carried by the audio channels in the form of frequency-modulated
infrared light. The transmitted signals are received by the INFRACOM Receiver IRX and can be monitored by
headphones. Receivers can be moved at will anywhere within the area that is fully illuminated by the radiators.
They can be switched to receive up to 32 channels.
With miniature-switches on the front panel the frequency band can be chosen and the channels can be switched
ON or OFF. With a rotating switch it is possible to assign up to 32 transmission channels.
3 infrared transmitter diodes on the front panel allow monitoring for the technician without radiators.
LEDs on the front panel are indicating the operation mode: channel ON (red) and audio signal available (green).
Use
In combination with the digital microphone management system CDSVAN, the system can provide the best
possible communication facilities for organized events that need to use several languages.
Each and every participant (a term often used is "delegate") can use the microphone system to speak, and what he
or she says will be translated simultaneously so that other delegates will be able to listen to it in one of the several
languages. This technique permits direct communication in several languages even at very large scale events.
It is a simple matter to set up the INFRACOM system in such a way that it is protected against eavesdropping from
outside. Since all information is transmitted in the form of light waves, it is possible to use opaque material as
necessary to limit the area to which it is to be transmitted. Dark curtains drawn across windows, for instance, are
enough to shield a room reliably from the outside world.
Although the CDSVAN system is most commonly used in combination with an INFRACOM interpretation system
and microphone-management system it is also possible to use it for other purposes.
During organized events, for instance, it is possible to use infrared light to transmit information to individual
participants wearing receivers without disturbing anyone else present.
Another example might be museums applications. There it is possible to provide information on individual exhibits
by means of infrared light radiated only to a limited area in front of the particular exhibit. Visitors listen to the
information with receivers and headphones.

Compact transmitter MSI8V
Front View
The CDSVAN Compact Transmitter MSI8V is part of the Congress Data System systems VAN (Virtual Audio
Network), which serves the cordless sound transmission by means of infrared light.
The sound signal is thereby converted into a frequency-modulated infrared light signal and emitted via transmitting
diodes. With special INFRACOM® receivers the light signal is recorded and re-converted into a sound signal,
which can then be heard on a set of headphones. Different frequencies of up to 32 channels can be transmitted
simultaneously with an FM narrow band modulation.
The CDSVAN Compact Transmitter MSI8V is used for modulating the sound signals on the different carrier
frequencies and for signal amplification.
The Compact Transmitter consists of a 19" housing (2HU).
Eight channels can be transmitted with one MSI8V (usually defined as Original + 7 languages).
On the front right-hand side of the Compact Transmitter MSI8V there is a POWER switch with a green ON LED
which shows whether the transmitter is switched on. Next to this there are three infrared test diodes for monitoring
the IR-signal even without IR-Radiator.
The operating elements of the eight infrared channels are also on the front side of the console.
Each infrared channel consists of a green AF LED for the original voice and interpreter voice, an ON LED, an ON /
OFF switch, two frequency band switches and a rotary switch for channel setting. This can be used to set the
channels independently of the frequency band switch.
Each channel can be set from OR - Ch31.
