The Sennheiser SDC 8200 conference and interpretation system is state of
the art and has been designed to meet the regulations in force. Neverthe-
less, the individual components of the SDC 8200 conference and interpre-
tation 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 permissi-
ble volume which is by law (in some countries) allowed to affect your hear-
ing 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 short-
ened 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 Sennheiser Digital Conference System – the new generation
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 sys-
tem 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 soft-
ware control program. In any case, the conference and interpretation sys-
tem 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 follow-
ing 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 par-
ticipant 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 con-
soles.
The conference consoles can also be operated with a central unit from the
SDC 8000 conference and interpretation system. In this case, the function-
ality 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.

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
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 cen-
tral units can be interconnected.
The interpretation capacity of the central unit is 28 languages. Two differ-
ent 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 confer-
ence 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 addi-
tional interpretation channels. The analog output unit can only be con-
nected 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
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 eas-
ily 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 man-
age delegate information such as name, organization, etc. During the
conference, this information is displayed on the computer screen, allow-
ing the conference manager to identify the participants who are cur-
rently 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 lan-
guage 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.

SDC 8200 system
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 con-
ference consoles are also turned on.
y The central units are turned on if the POWER switch ƾ 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 ƾ is set to position
“0” and the start display is not shown on the LC display.

lights up or flashes after the microphone key
ƺ has been pressed.
Turning on the central unit for the first time
When turning on the central unit for the first time, the text “Init
Refused” is shown on the displays of the conference consoles connected
to the central unit. The conference consoles cannot be detected by the cen-
tral 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 oper-
ational.
̈ First, initialize the conference consoles in order to assign each console
an internal microphone number. You can choose between two initial-

Adjusting the volume of the headphones connected to a conference con-
sole
With conference consoles which feature two headphone outputs but only
one volume control (SDC 8200 C, SDC 8200 CC, SDC 8200 DV and
SDC 8200 CV), the volume control adjusts the volume for both connected
headphones.
The volume is steplessly adjustable and the volume control has no stop. At
each system start-up, the volume is automatically reset to a medium level.
Caution!
Hearing damage due to high volumes!
This is a professional conference system. Commercial use
is subject to the rules and regulations of the trade associ-
ation 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 cor-
responding 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 short-
ened 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.

sions.
y take roll-call votes, i.e. you can see the name of each conference partici-
pant and his or her voting position.

VIP units are special delegate units which have the “rights” of a chairman
unit.
y With a VIP unit, you can take the floor at any time, regardless of the con-
ference mode and without first having to be assigned the “speaking
right”.
y If the chairperson presses the priority key , all active conference con-
soles – except for the VIP units – are turned off. The chairperson cannot
withdraw the “speaking right” from you.
y The VIP units are operated in the same way as the delegate units.

This system is capable of producing sound pressure
exceeding 85 dB(A). 85 dB(A) is the sound pressure cor-
responding 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 short-
ened in order to prevent hearing damage. The following
are sure signs that you have been subjected to excessive
noise for too long a time:
– You can hear ringing or whistling sounds in your
ears.
– You have the impression (even for a short time
only) that you can no longer hear high notes.

Structuring the SDC 8200 system
Determining maximum cable lengths
In the preceding examples, the standard length of “3 m” is always given
for the system cables between the conference consoles. However, it is no
problem to use other cable lengths or cables of differing lengths within the
same string.
However, if you wish to use longer cables, make sure that all consoles –
including the last one in a string – are supplied with a voltage of at least
30 V!
Calculating the voltage drop on the system cables
Every meter of system cable and every console in a string causes a voltage
drop. Thus, the further back a console is located in a string, the less voltage
it receives.
Delivery includes a the calculating program “Powercalc.exe” with which
you can easily calculate the voltage drops on the individual sections of a
string. In this way, you know even before setting up the conference system
whether it will work or not.
This program can also be downloaded from www.sennheiser.com.
Structuring an interpretation system
If your SDC 8200 system comprises interpreter consoles, these are usually
installed in acoustically isolated interpreter booths so that the interpreters
cannot disturb each other or the audience.
One booth with a team of interpreters is normally required per target lan-
guage. Within one language team, interpreters will take turns every
twenty minutes or so, in order to give each other an adequate break and
maintain a high level of quality.
Your SDC 8200 interpretation system can comprise
y a maximum of 224 interpreter consoles,
y a maximum fo 28 intepreter booths,
y a maximum of eight interpreter consoles per booth.
Within a booth, each interpreter console has to be assigned a number, with
the numbering starting always from 1.
The interpreter consoles can be connected anywhere in the cable strings.

Structuring the SDC 8200 system
Selectable modes between or within interpreter booths
With the SDC 8200 system, you can choose between three “modes
between booths” and two “modes in booth”.
Via the “modes between booths”, you fix the responsibilities of interpret-
ers who are seated in different booths but interpret into the same target
language (one on the A-channel and another on the B-channel).
Via the “modes in booths”, you fix the responsibilities of interpreters who
are seated in the same booth and interpret into the same target language.
Mode between booths: “Mixed“
Interpreters who are seated in different booths but interpret into the same
target language can activate their interpreter consoles any time by press-
ing the MIC key ƺ – even simultaneously.
When two interpreters simultaneously interpret into the same target lan-
guage, the red signal light ring ¹ and the “Microphone active” LED ƹ on
their consoles light up.

matically turn off the currently active interpreter console.
In “Override” mode, an interpreter console that was just turned off can
only be turned on again if the interpreter console by which it was turned
off is deactivated.

The “auto-floor” function
If the original floor language is not a language of which all interpreters
have a complete understanding and from which they work, you can enable
the auto-relay interpretation function (auto-floor): The original floor lan-
guage is interpreted into a language understood by all interpreters. This
interpretation is automatically “relayed” to the floor channel of all other
interpreters and serves as the basis from which they interpret into their
respective target languages.
Example:
The active languages at a conference are English, German and French
(active languages are the languages into which interpretation is pro-
vided).
However, some of the delegates speak Russian, a language of which
only one interpreter has a complete understanding. This interpreter
interprets the contributions of the Russian delegates into English,
which the other interpreters then interpret into their respective target
languages. The English interpretation is also fed to the English inter-
pretation channel.

Structuring the SDC 8200 system
Using external equipment
External audio signals can be fed to the conference and interpretation sys-
tem and channels (floor channel and interpretation channels) can be out-
put. You can, for example,
y connect a wireless microphone, enabling a speaker to move around
freely and to speak from anywhere in the room,
y feed external audio signals (e.g. the soundtrack of a video, music,
announcements from a tape, etc.) into the system,
y connect a PA system,
y connect an infrared language distribution system,
y directly transmit channels to broadcasting and TV stations,
y and record individual channels for documentation or archiving purposes.
Note!
Please note that a total of two audio sources can be connected to the
central unit and that a total of four channels plus the floor channel can
be output. If you wish to output more channels, you require the
optional SDC 8200 AO analog output unit.
Connecting external audio sources
Via the two XLR-3F sockets (AUX IN 1 º and AUX IN 2 ¾) of the central
unit, external audio sources which output a balanced mono signal can be
connected to the conference system.
External audio sources are, for example:
y wired microphones
y wireless microphones
¾
º
y the audio output of a video recorder
y a CD player
The signals available at the audio inputs AUX IN 1 and AUX IN 2 are fed to
the floor channel which is output via the consoles’ built-in loudspeakers.
For information on how to turn on the audio inputs and how to adjust the
volume and the input sensitivity, see:
Using the audio outputs of the central unit
The floor channel is available at the XLR-3M audio output µ (AUX OUT 1)
and the 15-pole sub-D socket ƺ (AUX OUT).
The signals of up to six interpretation channels are available at the outputs
AUX OUT 1-2-3-4-5-6 of the 15-pole sub-D socket ƺ.
Additional interpretation channels can be output via the XLR-3M audio
outputs of an SDC 8200 AO analog output unit connected to the central
units data out port ƹ.

Connecting additional equipment
Via the two audio inputs AUX IN 1 and AUX IN 2 of the central unit, you can
connect microphones with suitable preamplifiers or you can feed audio
signals from additional audio equipment to the conference system.
The external audio signals are fed to the floor channel which is output via
the consoles’ built-in loudspeakers.
The output signal of the floor channel is available at the audio output AUX
OUT 1. Via the five audio outputs AUX OUT 2 to AUX OUT 6, you can output
any desired channel (floor channel or interpretation channels).
Via the audio outputs, you can:
y connect a PA system via which the floor channel or an interpretation
channel can be transmitted to e.g. the foyer or another room,
y transmit the audio signal of the floor channel or an interpretation chan-
nel as “original soundtrack” to a broadcasting station,
y connect an infrared language distribution system to the central unit,
allowing guests or participants who don’t have their own conference
console to follow the conference via infrared headphones. With the
SDC 8200 CU central unit, guests or participants can choose between the
floor channel and up to 28 interpretation channels. With the SDC 8200
CU-M central unit, guests or participants can choose between the floor
channel and up to four interpretation channels.
Optionally, you can connect an SDC 8200 AO analog output unit to the cen-
tral unit. The analog output unit features nine XLR-3M audio outputs via
which you can output the floor channel and up to eight additional interpre-
tation channels and to which you can connect external equipment such as
a recording unit, etc.
Connecting external audio sources
You can connect external audio sources such as wired microphones, wire-
less microphone systems, the audio output of a video recorder, a CD player,
etc. to the central unit. The audio sources to be connected must deliver a
balanced mono signal at the XLR-3F sockets.
The external audio signals are fed to the floor channel which is output via
the consoles’ built-in loudspeakers.
To connect an audio source:
̈ Use an audio cable with XLR-3 connectors to connect the audio source
to one of the XLR-3F sockets (AUX IN 1 º or AUX IN 2 ¾) of the central
unit.
̈ If necessary, adapt the input sensitivity and the volume of the audio
input via the central unit’s operating menu (see “Adjusting the input

Configuring the audio inputs and outputs of the central
unit and the anaolog output unit
You can connect external audio sources such as a CD player, a microphone
with preamplifier etc. to the central unit’s audio inputs.
Instead of connecting an external audio source, you can connect the audio
output of a conference system installed in a separate room to carry out a
remote conference.
Via the audio outputs, you can connect e.g. a recording unit.
Via the “Aux-In/Out” menu, you can configure the central unit’s audio
inputs and outputs for the connected equipment.

Configuring the SDC 8200 system
The row marked in grey shows the factory-preset standard configuration.
The column marked in grey shows the reference output OUT 1 and the
channel numbers assigned.
Example:
Your system accommodates 16 interpretation channels and you want
to output each interpretation channel via its own audio output. To do
so, you require two analog output units whose outputs have to be con-
figured as follows:
̈ The factory-preset standard configuration of the first analog output
unit remains unchanged (the channels 1 to 8 are output via the unit’s
outputs OUT 1 to OUT 8, the floor channel is output via output OUT 0).
̈ Make sure that the second analog output unit is not connected!
̈ Open the second analog output unit by removing the seven screws on
the top of the housing as well as the screw on the front panel with a
2.0 mm Allan key and lift the cover off the unit.
̈ Leave the two DIP switches in position “OFF” as shown in the illustra-
0
tion on the left.
ON
̈ Use a screwdriver to set the rotary switch to position “9”.
̈ Close the housing and tighten the screws. In order to avoid that the two
analog output units are later confused, we recommend marking the
second analog output unit with a sticker.

Appendix A: Camera control protocol
Appendix A: Camera control protocol
The SDC 8200 conference and interpretation system supports camera con-
trol. The central unit sends a control command to the connected camera
control:
y when a delegate or chairman unit is activated,
y when a delegate or chairman unit is deactivated,
y when all active microphones are deactived one after the other,
y when all active microphones are deactived simultaneously
(priority function),
y every 5 seconds for synchronization.
These commands are evaluated by the camera control which then auto-
matically aims the camera at a speaker and adjusts the focus.
The camera control must be connected to the SDC 8200 CU central unit’s
COM 2 interface (RS 232 connection). The settings for the communications
port for camera control are:
Bits per second: 19,200
Data bits:
Parity:
8
None
1
Stop bits:
Flow control:
None
The syntax of the commands
All commands sent by the SDC 8200 CU central unit start with a “%” sign.
The last character is a character which states the end of the transmission.
Just before the end-of-transmission character, there are four characters
within the command sent to the camera control which account for the CRC
checksum.
STX “%”

sion Character

The CRC checksum is in uppercase hexadecimal form while all other num-
bers are in decimal form.

Appendix B: Control panel protocol
Appendix B: Control panel protocol
The SDC 8200 conference and interpretation system supports a control
panel. The central unit sends a control command to the connected control
panel:
y when a delegate or chairman unit is activated,
y when a delegate or chairman unit is deactivated,
y when a microphone goes into request mode,
y when all active microphones are deactived simultaneously
(priority function).
The control panel sends a control command to the central unit:
y when a delegate or chairman unit is to be activated,
y when a delegate or chairman unit is to be deactivated,
y when the control panel is to be reset (Reset).
The control panel must be connected to the central unit’s COM 2 interface
(RS 232 connection). The settings for the communications port for the
control panel are:
Bits per second: 19,200

Appendix C: Repeater for the SDC 8200 system
Appendix C: Repeater for the SDC 8200
system
A repeater is used to boost the signal on a system cable. When a system
cable reaches a length of 100 m, the signal over the system cables
becomes too weak.
You can insert a repeater into the system cable to boost this signal.
The repeater features an IN and an OUT socket. The cable from the central
unit should be connected to the IN socket ᕢ and the following daisy-chain
of conference consoles should be connected to the OUT socket ᕡ.
It is also possible to connect a cable daisy-chain with conference consoles
to the central unit and – when the cable daisy-chain reaches 100 m – insert
a repeater into the daisy-chain.
The DC power supply which reaches the repeater is 30 to 60 VDC straight
from the central unit.
The repeater features three LEDs:
·
» UPLINK FAIL LED: lights up when there is no communication with a con-
³
ference console (normally OFF).
¿ DOWNLINK FAIL LED: lights up when there is no communication from
the central unit (normally OFF).
»
´ POWER SUPPLY LED: lights up when power is supplied to the repeater
(normally ON).
For purchasing a repeater, please contact your Sennheiser partner.
