Important remarks

For customers in the EU and in the USA

Our equipment has been tested and complies with the requirement of the CE test. This guarantees the

protection against harmful interferences, when the equipment is operating in a commercial environment. If

the unit is not proper installed to this user manual it may causes radio interferences. Any changes or

modifications not explicit approved in this manual could void your authority to operate this equipment.

For customers in the United Kingdom

The wires in the main lead are colored in accordance to the following codes:

Green-and-yellow: Earth

Blue: Neutral

Brown Live

If the colors of the wires in the mains lead of this unit are not corresponding with the colored markings of the

terminals in your plug, so please proceed as follows:

The green-and-yellow wire must be connected to the plug terminal marked with the letter E, with the safety

earth symbol or with green-and-yellow colour. The blue wire must be connected to the terminal marked with

the letter N or with black colour. The brown wire must be connected to the terminal marked with the letter L

or with red colour.

The equipment must be connected to earth!

Safety

Check that the operating voltage of the unit is identical with the voltage of your local mains power. If a

voltage conversion is required, consult your BRÄHLER ICS dealer or qualified personnel.

Should any liquid or solid object fall into the cabinet, unplug the unit and have it checked by qualified

personnel before it will be used again. Unplug the unit from the wall outlet or set the Main Power switch to

OFF if it is not used for several days. To disconnect the cord, pull it out holding the plug. Never pull the cord

itself.

Installation

Allow adequate air circulation to prevent internal heat accumulation. Do not place the unit on a surface (rugs,

blankets, etc.) that may block the ventilation holes.

Do not install the unit in locations near heat sources such as radiators or air ducts, nor in places exposed to

direct sunlight, excessive dust or humidity, mechanical vibration or shock.

To avoid condensation do not install the unit where the temperature may increase rapidly.

Cleaning

To keep the surface of the housing in a proper condition, periodically clean it with a soft cloth. Large staining

may be removed with a cloth lightly dampened with a mild detergent. Never use organic solvents such as

thinners or abrasive cleaners since these might damage the surface.

Repacking

Save the original shipping box and packing material. For maximum protection, re-pack the unit as originally

packed from the factory.

If not supplied with the equipment, a complete transportation and storage box system is available from

BRÄHLER ICS. We recommend using this system for long-term protection and care.

General

Please keep this manual together with the CDSVAN Compact Transmitter MSI8V Band IV. If you hand on

the units to third parties, please include this manual.

CDSVAN MSI8V BIV

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

LINE-OUT: eight sockets for audio recording

RF-LINK: socket for cascading (RF) with further MSI8V BAND 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.
