Overview
The Compact Transmitter MSI8V BAND IV 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 IRad, which are directly connected to the MSI8V BAND IV. 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 BAND II/IV 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 conference 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 eaves-
dropping 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 BAND IV
Front View
The front of the MSI8V compact transmitter is equipped with:
power switch with green Einschaltkontrollleuchte
8 green LEDs (AF) to display "Audio available"
8 red LEDs (ON) to indicate "channel on"
8 DIP switches for setting the frequency band
8 rotary switches for channel selection
3 emitting diodes for test mode (allowing the technician listening without radiator)
Rear View
The Compact Transmitter MSI8V B IV has the following sockets on the rear side:
VAN-IN (RJ45 socket) for connecting to the CDSVAN PC (Computer)
VAN-LINK (RJ45 socket) for cascading (Audio) with a second MSI8V B IV

RADIATORS / IR-LINE: 2 x BNC sockets for connecting distribution SV/BNC-IV.
Mains power connector.
Wiring the radiators in band IV you must be aware of the following: Due to the higher carrier
frequencies the BNC cables to the radiators must have the same length. Using two radiators in a
row, the highest distance should not be greater than a meter. Otherwise, there will be overlaps or
extermination.
