The Sennheiser SDC 8200 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 8200 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 regula-
tions,
y the system is converted or altered incorrectly, y the safety instructions are not observed.

Attention! High Volume!

This is a professional conference system. Commercial use is subject to the rules and regulations of the trade association responsible. Sennheiser, as the manufacturer, is therefore obliged to expressly point out possible health risks arising from use.
This system is capable of producing sound pressure exceeding 85 dB(A). 85 dB(A) is the sound pressure corresponding to the maximum permissi­ble volume which is by law (in some countries) allowed to affect your hear­ing for the duration of a working day. It is used as a basis according to the specifications of industrial medicine. Higher volumes or longer durations can damage your hearing. At higher volumes, the duration must be short­ened in order to prevent hearing damage. The following are sure signs that you have been subjected to excessive noise for too long a time:
y You can hear ringing or whistling sounds in your ears. y You have the impression (even for a short time only) that you can no
longer hear high notes.

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 8200 – the digital conference and interpretation system
SDC 8200 – the digital conference and interpretation system
The new SDC 8200 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 8200 conference and interpretation system is an ideal choice for both small seminars with up to 20 participants and large international conferences with a maximum of 1024 participants.
An important feature of the SDC 8200 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.

Overview of the components of the SDC 8200 system

Overview of the components of the SDC 8200 system
An SDC 8200 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 sys-
tem

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. All conference consoles have voting keys, allowing all conference participants to participate in voting sessions from their con­soles.
The conference consoles can also be operated with a central unit from the SDC 8000 conference and interpretation system. In this case, the function­ality of the conference consoles depends on the functions and features of the central unit. The conference consoles are connected in series. One cable string can comprise up to 20 conference consoles and up to six cable strings (i.e. up to 120 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 1024 consoles.
10
Overview of the components of the SDC 8200 system

The interpreter consoles

The interpreter console incorporates all functions of a conference console but offers additional features required by the interpreters.
The interpreter consoles are required if simultaneous interpretation is offered at a conference.

The central units

You can choose between the SDC 8200 CU central unit for larger and the SDC 8200 CU-M central unit for smaller conference systems (see “Features of the central units” on page 116).
Both central units can also be operated with conference consoles from the SDC 8000 conference and interpretation system.

The SDC 8200 CU central unit

The SDC 8200 CU central unit is the core of the SDC 8200 conference and interpretation system and, at the same time, serves as an interface for additional audio systems.
Via the operating menu of the SDC 8200 CU central unit, the conference and interpretation system can be configured for any room, any number of participants and any conference use. The central unit serves to manage the entire conference and interpretation system.
On the SDC 8200 CU central unit, you can choose between ten conference modes. However, the selection of some of the conference modes only makes sense if your conference and interpretation system is PC controlled.
The SDC 8200 CU central unit has a built-in power supply for powering up to 120 conference consoles. For larger conference systems, up to 12 cen­tral units can be interconnected.
The interpretation capacity of the central unit is 28 languages. Two differ­ent licenses are available for eight or 28 interpretation channels. The floor channel and four interpretation channels can be operated license-free.

The SDC 8200 CU-M central unit

The SDC 8200 CU-M central unit is the core of the SDC 8200 conference and interpretation system and, at the same time, serves as an interface for additional audio systems.
Via the operating menu of the SDC 8200 CU-M central unit, the conference and interpretation system can be configured for any room, any number of participants and any conference use. The central unit serves to manage the entire conference and interpretation system.
On the SDC 8200 CU-M central unit, you can choose between ten confer­ence modes. However, the selection of some of the conference modes only makes sense if your conference and interpretation system is PC controlled.
The SDC 8200 CU-M central unit has a built-in power supply for powering up to 50 conference consoles. However, it is not possible to interconnect several SDC 8200 CU-M central units in order to realize larger conference systems.
The floor channel and four interpretation channels can be operated license-free.

The SDC 8200 AO analog output unit

The analog output unit has nine audio outputs to which you can connect:
y an infrared language distribution system, y PA systems, y recording units, etc.
One analog output unit can output the floor channel and up to eight addi­tional interpretation channels. The analog output unit can only be con­nected to the SDC 8200 CU central unit. Up to four analog output units can be connected to the SDC 8200 CU central unit using a conference bus cable. Power for the analog output units is supplied via the SDC 8200 CU central unit.

The system cables

Power supply of the conference consoles is via the system cables which also transmit the digital audio and status information.

The software control

12
The optional software control allows a conference manager to control the entire conference via a PC. In contrast to controlling the conference via the central unit, the software control provides several extra functions:
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.
Overview of the components of the SDC 8200 system
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 8200 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.

The system cables

The system cables required for your planned conference and interpreta­tion system must be ordered separately. The system cables are available with lengths of 2 m, 3 m, 5 m, 10 m, 20 m and 50 m.
Via the system cables, you can:
y interconnect the conference and interpreter consoles, y interconnect up to 10 central units for setting up a large conference and
interpretation system,
y connect an SDC 8200 AO analog output unit to the central unit, y connect cable strings to the central unit.
The system cables must meet the following specifications:
Shielded RJ 45 modular plug, cat 5(e)
Black cable booth with clip protector
Round STP cable, cat 5(e), 24AWG
Grey cable booth with clip protector

Depending on the type of delegate unit, conference participants can:
y listen, take the floor or make a request to speak, y receive simultaneous interpretation, y participate in voting sessions.
In addition to the functions and features of the delegate units, the chair-
man unit allows to:
y start a voting session (SDC 8200 CV only), y mute all active delegate units (priority function).
The interpreter consoles are exclusively used by the interpreters.
The central unit is operated by the conference manager – either directly or via an optional PC with software control.

Turning the conference and interpretation system on/off

You turn the conference and interpretation system on by turning on the central unit(s) (see the following sections). In doing so, all connected con­ference consoles are also turned on.
y The central units are turned on if the POWER switch is set to position
“I” and the start display is shown on the LC display.
y The central units are turned off if the POWER switch is set to position
“0” and the start display is not shown on the LC display.
y The conference consoles are turned on if the “Microphone active” LED
lights up or flashes after the microphone key has been pressed.

Turning on the central unit for the first time

When turning on the central unit for the first time, the text “
Refused” is shown on the displays of the conference consoles connected
to the central unit. The conference consoles cannot be detected by the cen­tral unit, since they have not yet been assigned a microphone number. Your conference system is not yet operational.
Note!
Once you have configured your conference and interpretation system, the configuration will be retained in memory on turn-off. When turning on the central unit again, your conference system is immediately oper­ational.

7 Initialise Units
왘 First, initialize the conference consoles in order to assign each console
an internal microphone number. You can choose between two initial­ization modes: automatic (see page 85) and manual (see page 85) ini­tialization.

Turning interconnected SDC 8200 CU central units on/off

When turning on a conference and interpretation system with several SDC 8200 CU central units, it is important that the central units are turned on in the correct order.
왘 First turn on the “master” central unit.
왘 Then turn on the “slave” central units in the order in which they are
connected to the “master”.
To turn a central unit on:
왘 Set the POWER switch to position “I”.
The consoles which are powered via this central unit are ready for oper­ation as soon as they are initialized.
The start display is shown on the LC display of this central unit.
>Volume =
P1 P2 P3 P4 P5 P6
Note!
It is, however, possible to simultaneously turn on interconnected cen­tral units via a switchable multiple socket.
To turn a central unit off:
왘 Set the POWER switch to position “0”.
The display goes off. All consoles which were powered via this central unit are also turned off.
Note!
The central units are not disconnected from the mains when they are turned off. To disconnect the central units from the mains, pull their mains plugs out of the wall outlets.
