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 Sennheiser Digital Conference System – the new generation  
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.

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.

Expansion stage (3): several central units with up to 900 consoles  
For larger conference and interpretation systems with up to 900 consoles,  
you can interconnect a total of 10 central units. The additional central  
units are connected as “slaves” to the central unit configured as “master”.  
If the conference and interpretation system is to be PC controlled, the PC  
must be connected to the “master” central unit.  
To set up a conference system with several central units, you first have to  
interconnect the consoles in cable strings and then connect the cable  
strings to the central units. Finally, you interconnect the central units (see

for interconnecting the central units must not exceed 3 m.  
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 want 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!

Structuring the SDC 8000 system  
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 Microsoft Excel document 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.  
Structuring an interpretation system  
If your SDC 8000 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  
language. 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.  
With the SDC 8000 system, a maximum of eight interpreter consoles can  
be installed 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 8000 system  
Selectable modes between or within interpreter booths  
With the SDC 8000 system, you can choose between three “modes  
between booths” and two “modes in booth”.  
Via the “modes between booths”, you fix the responsibilities of  
interpreters 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  
pressing the MICRO key ƺ – even simultaneously.  
When two interpreters simultaneously interpret into the same target  
language, the red signal light ring ¹ and the “Microphone active” LED ƹ  
on their consoles light up.

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  
language 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  
provided).  
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  
interpretation channel.

Structuring the SDC 8000 system  
Using external equipment  
External audio signals can be fed to the conference and interpretation  
system and channels (floor channel and interpretation channels) can be  
output.  
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 three channels plus the floor channel can  
be output. If you wish to output more channels, you require the  
optional SDC 8000 AO analog output unit.  
Connecting external audio sources  
Via the two XLR-3F sockets (AUX IN 1 and AUX IN 2) 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  
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:  
y “Turning the audio inputs or outputs on and off” on page 95,  
y “Adjusting the input level of an audio input” on page 96 and  
y “Adjusting the input sensitivity of an audio input” on page 96.  
Transmitting the floor channel and the interpretation channels to  
broadcasting and TV stations  
Important conferences and specialist congresses are of great interest to  
the public. The SDC 8000 conference and interpretation system, therefore,  
allows you to transmit the floor channel and the interpretation channels  
e.g. to broadcasting and TV stations.  
The floor channel is available at the XLR-3M audio output (AUX OUT 1) and  
the 9-pole sub-D socket (AUX OUT 2).

Structuring the SDC 8000 system  
The signals of up to three interpretation channels are available at the  
outputs AUX OUT 3-4-5 of the 9-pole sub-D socket.  
Additional interpretation channels can be output via the XLR-3M audio  
outputs of an SDC 8000 AO analog output unit connected to the central  
unit.  
Transmitting the floor channel or an interpretation channel  
via a PA system  
Via the central unit’s XLR-3M audio output or via an audio output of the  
SDC 8000 AO analog output unit, you can connect a PA system via which  
the floor channel or an interpretation channel can be transmitted to e.g.  
the foyer or another room.  
For information on how to select the channel to be output via an audio  
output, see “Assigning a channel to an audio output” on page 95.  
Transmitting the floor channel and the interpretation channels via an  
infrared transmission link  
You can connect the control of an infrared transmitter to the central unit,  
allowing guests or participants who don’t have their own conference  
console to follow the conference via infrared headphones. These guests or  
participants can choose between the floor channel and the interpretation  
channels.

Fixing the central unit feet  
To ensure that the cell transmitter cannot slip on the surface on which it is  
placed, four self-adhesive soft feet are supplied.  
Note:  
Do not use these feet if rack-mounting the cell transmitter.  
̈ Ensure that the base of the central unit is clean and free from grease  
before mounting the feet.  
̈ Fix the feet to the base of the central unit by peeling off the safety  
paper and fitting them as shown in the diagram on the left.  
Attention!  
Some furniture surfaces have been treated with varnish, polish or  
synthetics which might become stained when they come into contact  
with other synthetics. Despite a thorough testing of the synthetics  
used by us, we cannot rule out the possibility of staining, since we don’t  
know your furniture.  
Rack-mounting several central units  
For larger conference and interpretation systems with several central  
units, we recommend mounting the central units into a rack.  
̈ Mount the central unit into a 19" rack and fix it to the rack by means of

Setting up the SDC 8000 system  
Note!  
The entire conference and interpretation system is configured,  
managed and controlled exclusively via the “master” central unit.  
All operating controls on the “slaves” are locked. This is indicated by a  
“key” symbol (  
) in the lower right corner of the display.  
Turning the central units on and off  
When turning on a conference and interpretation system with several  
central units, it is important that the central units are turned on in the  
correct order.  
̈ First turn on the “master” central unit.  
̈ Then turn on the “slave” central units in the order in which they are  
connected to the “master”.  
To turn a central unit on:  
̈ Set the POWER switch ƾ 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.

are also turned off.  
ƾ
Note!  
It is, however, possible to simultaneously turn on interconnected  
central units via a switchable multiple socket.  
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 two audio outputs  
AUX OUT 1 and AUX OUT 2. Via the three audio outputs AUX OUT 3 to 5,  
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,

Setting up the SDC 8000 system  
y transmit the audio signal of the floor channel or an interpretation  
channel 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. These guests  
or participants can choose between the floor channel and up to 28  
interpretation channels.  
Optionally, you can connect an SDC 8000 AO analog output unit to the  
central unit. The analog output unit features nine XLR-3M audio outputs  
via which you can output the floor channel and up to eight additional  
interpretation 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,  
wireless 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  
sensitivity of an audio input” on page 96 and “Adjusting the input level  
of an audio input” on page 96).  
¾
º
You can turn the audio inputs on and off via the central unit’s operating  
menu (see “Turning the audio inputs or outputs on and off” on page 95).  
Carrying out remote conferences  
Instead of connecting an external audio source to the audio input of your  
conference system, you can connect the audio output of a conference  
system installed in a separate room to carry out a remote conference. The  
participants of both conferences can then participate in a common  
conference.  
To connect two conference systems installed in separate rooms, you  
require two XLR cables with two XLR-3 connectors respectively:

Turning on the central unit for the first time  
When turning on the central unit for the first time, the text “I ni t  
Re f us e d” 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.  
̈ First, initialize the conference consoles in order to assign each console  
an internal microphone number. You can choose between two  
initialization modes: automatic and manual initialization.

separate interpretation system. To be able to make use of the  
interpretation system, you require the SDC 8000 ID interpreter consoles.  
Via the “I nt e r pr e t a t i on” menu, you can quickly and easily configure  
the interpretation system.  
Working with the interpreter configuration  
The following features of your interpretation system are put together in  
an interpreter configuration:  
y The number of booths and the number of interpreter consoles per booth  
(see “Setting the max. number of interpreter booths/languages” on  
page 86 und “Setting the max. number of interpreter consoles per  
booth” on page 86).  
y The operating modes between booths and within booths (see  
“Configuring the operating mode between booths” on page 87 and  
“Configuring the operating mode within a booth” on page 87).  
y The main target languages of the respective booths (see “Configuring  
the main target language (A-channel) of a booth” on page 88).  
y The second target languages of the respective booths (see “Configuring  
the second target language (B-channel) of a booth” on page 88).  
y The booth from which a relay interpretation is delivered (see “Enabling  
the auto-relay interpretation function (Auto-floor)” on page 89).  
y The initialization of the interpreter consoles (see “Half-automatically  
initializing all interpreter consoles on the central unit” on page 90).

Configuring the SDC 8000 system  
You can save two different interpreter configurations in the central unit:  
“CONFI G 1” and “CONFI G 2”. This allows you to quickly and easily adapt  
you interpretation system to a new conference. In addition, you can  
modify the currently active interpreter configuration at any time.  
Creating a new interpreter configuration  
To create a new interpreter configuration:  
1. Define the number of booths as described under “Setting the max.  
number of interpreter booths/languages” on page 86.  
If you change the number of booths after you have created and saved  
the interpreter configuration, the new number of booths will  
automatically be saved in the configuration.  
2. Define the number of interpreter consoles per booth as described under  
“Setting the max. number of interpreter consoles per booth” on  
page 86.  
If you change the number of interpreter consoles after you have  
created and saved the interpreter configuration, the new number of  
interpreter consoles will automatically be saved in the configuration.

Enabling the auto-relay interpretation function (Auto-floor)  
If the original floor language is a language of which all interpreters have a  
complete understanding and from which they work, you do not have to  
enable this function. In this case, all interpreters interpret the original floor  
language into their respective target languages. These interpretations are  
then fed to the corresponding interpretation channels.  
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  
language 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.  
To enable the auto-relay interpretation function (auto-floor):  
Attention!  
The interpreter who delivers the relay interpretation has to choose the  
B-channel!  
̈ From the central unit’s operating menu, choose “I nt e r pr e t a t i on”,

̈ Use a screwdriver to carefully loosen the fuse holder and pull it out  
completely.  
̈ Remove the faulty fuse.  
̈ Insert a new fuse (5 x 20 mm, 3.15 AT).  
Conference/interpreter console does not work  
̈ Make sure that the system cables between the central unit and the  
conference/interpreter console are not defective and that the system  
cables are connected correctly.  
̈ Make sure that the central unit is connected to the mains and that it is  
turned on.  
Only the microphone of the chairman unit can be activated  
̈ Make sure that the max. number of simultaneously active microphones  
is set to at least “1” (see “Setting the speaker limit” on page 80).  
Maintenance and care  
̈ Use a damp cloth for cleaning the components of the conference and

Appendix A: Camera control protocol  
Appendix A: Camera control protocol  
The SDC 8000 conference and interpretation system supports camera  
control. 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  
automatically aims the camera at a speaker and adjusts the focus.  
The camera control must be connected to the SDC 8000 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  
Note!  
In order to activate camera control on the central unit, you have to  
purchase the serial output license SDC 8000 S-SO (Cat. No. 9855)  
The syntax of the commands  
All commands sent by the SDC 8000 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.

panel:  
y when a delegate or chairman unit is activated,  
y when a delegate or chairman unit is deactivated,  
y 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 SDC 8000 CU central unit’s

Appendix C: Repeater for the SDC 8000 system  
Appendix C: Repeater for the SDC 8000  
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:  
·
³
» UPLINK FAIL LED: lights up when there is no communication with a  
conference 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).
