Safety information

Safety information
The Sennheiser SDC 8000 conference and interpretation system is state of the art and has been designed to meet the regulations in force. Nevertheless, the individual components of the SDC 8000 conference and interpretation system can cause danger for persons and material assets if:
y the system is not used as intended, y the system is set up by personnel not familiar with the safety
regulations,
y the system is converted or altered incorrectly, y the following safety instructions are not observed.
Warning!
If the components of the conference and interpretation system are set up improperly, persons can stumble over cables, fall and suffer serious injury! This can also cause severe damage to units and cables. Place the components of the system on flat surfaces only. Lay the cables in such a way that no-one can stumble over them.
Attention!
The central units generate heat! If the heat generated cannot dissipate, the central units can be destroyed or combustible materials nearby can catch fire. Make sure that the air vents of the central units are not covered or blocked. Keep combustible materials away from the central units.
Attention!
If liquids or small parts which conduct electricity find their way into the interior or to the sockets or plug contacts of the units, this can cause a short circuit which may damage the units! Keep liquids and small parts which conduct electricity away from the units! Before cleaning the units, disconnect all central units from the mains by removing the plug. For cleaning the system components, only use a slightly damp cloth. Do not use solvents as they can damage the surfaces.
Attention!
If you connect defective or unsuitable accessories, the system components can be destroyed! Only use the connection cables available from Sennheiser electronic GmbH (see “The system cables” on page 24). Sennheiser makes no warranty as to cables not manufactured by Sennheiser.
Warning!
This is a class A product. In a domestic environment this product may cause radio interference in which case the user may be required to take adequate measures.

SDC 8000 – the digital conference and interpretation system

SDC 8000 – the digital conference and interpretation system
The new SDC 8000 conference and interpretation system from Sennheiser utilizes all advantages of digital communications technology and offers its users a series of important features:
y Decentralized, clear sound reproduction y Excellent speech intelligibility due to 16-bit audio transmission y Easy installation and straight-forward operation y Conference consoles are extremely easy to operate y Delegate interaction (e.g. with voting sessions) y Interpretation facility y Extended functionality y Possibility of connecting an infrared language distribution system
SDC stands for S of mobile and expandable conference and interpretation equipment.
The SDC 8000 conference and interpretation system is an ideal choice for both small seminars with up to 15 participants and large international conferences with a maximum of 900 participants.
An important feature of the SDC 8000 conference and interpretation system is its modular design. Even if, at first, the system is only required for small conferences, you can later easily add conference consoles and a software control program. In any case, the conference and interpretation system can:
y be set up quickly, since all consoles are connected in series (single-cable
system),
y be adapted easily to any room and any number of participants.
ennheiser Digital Conference System – the new generation

Overview of the components of the SDC 8000 system

Overview of the components of the SDC 8000 system
An SDC 8000 conference and interpretation system consists of the following components:
y Conference consoles for delegates and chairmen y Interpreter consoles y Central units y System cables y If required, a software control for the conference and interpretation
system

The conference consoles

The conference console features a built-in loudspeaker, allowing the participant to directly hear all audio information, e.g. speeches, presentations or any other audio material. This decentralized “loudspeaker system” ensures excellent sound quality at a pleasant volume throughout the entire room.
The console’s electret microphone transmits every word in excellent audio quality. The red signal light ring on the microphone serves as an indicator of who is allowed to take the floor.
The conference consoles are available in six different versions with varying levels of functions. Via special consoles with voting function, the conference participants can participate in voting sessions from the consoles.
The conference consoles are connected in series. One cable string can comprise up to 15 conference consoles and up to six cable strings (i.e. up to 90 conference consoles) can be connected to a single central unit. You can, however, interconnect several central units to set up conference systems with up to 900 consoles.

Overview of the components of the SDC 8000 system
y Additional functions for controlling the microphones:
Via the computer screen, the conference manager can easily monitor which participants have made a request to speak, which participants are currently speaking, etc. All participants can be identified and displayed by name. Individual conference consoles can be directly activated or deactivated by clicking the mouse key.
y Display of voting results as diagrams:
The results of votings can be presented graphically and can, for example, be displayed via a connected projector. In addition, it is possible to take voting sessions with chip cards. Chip cards make sure that only those who have a chip card have access to the voting function.
y Configuration of special conference consoles:
The conference manager can configure more than one chairman unit as well as VIP units.
y Interpreter management software:
This software module allows the conference manager to quickly and easily configure the interpreter booths and interpreter consoles (i.e. assign a language to the A-channel and B-channel of an interpreter console, choose the operating mode between and within the interpreter booths, etc.).
y Delegate database:
The delegate database allows the conference manager to centrally manage delegate information such as name, organization, etc. During the conference, this information is displayed on the computer screen, allowing the conference manager to identify the participants who are currently speaking or those who wish to make a contribution by name. It is also possible to use the information contained on the chip cards.

The technology used

Both the control and sound transmission of the SDC 8000 conference and interpretation system are fully digital, resulting in excellent audio. The language channels are transmitted within a frequency range of 100 Hz to 14 kHz at 16-bit resolution.
The conference consoles are connected to each other and to the central unit by means of system cables.
