Operating the components of the SDC 8200 system Using the interpreter console As soon as your interpreter console is configured, you can use it as follows: Make sure that the correct channel for the target language is set (see “Switching between the A-channel and the B-channel” on page 39): If you interpret into the main target language assigned to your booth, choose the A-channel.
Before a conference starts, you have to configure your entire conference and interpretation system via the central unit’s operating menu (see “Configuring the SDC 8200 system” on page 61); it is, however, possible to make changes to individual settings during a conference.
Operating the components of the SDC 8200 system Simultaneously press the F1 and F3 function keys and keeps them pressed for three seconds. If you release the two function keys after three seconds, the “key” symbol ( ) appears in the lower right corner of the display.

In conference systems of expansion stage (2), up to six cable strings with up to 20 consoles each (6 x 20 = 120) can be connected to a single SDC 8200 CU central unit. This is the maximum number of consoles that can be connected to a single 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 “Interconnecting several central units (SDC 8200 CU central unit only)” on page 54). <=10 m <=10 m...
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.
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 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).
Structuring the SDC 8200 system Mode in booths: “Mixed” Interpreters who are seated in the same booth and interpret into the same target language can activate their interpreter consoles any time by pressing the MIC key – even simultaneously. When two interpreters simultaneously interpret into the same target language, the red signal light ring and the “Microphone active”...

Via the central unit’s XLR-3M audio output or via an audio output of the SDC 8200 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.
Connect the mains cable to the mains (100 – 240 V, 50 – 60 Hz). Rack-mounting several SDC 8200 CU central units For larger conference and interpretation systems with several SDC 8200 CU central units, we recommend mounting the central units into a rack.
You can only interconnect SDC 8200 CU central units. The length of the system cables between the SDC 8200 CU central units must not exceed 10 m. If you wish to interconnect several SDC 8200 CU central units, we recommend mounting the central units into a rack.
Setting up the SDC 8200 system Turning the interconnected SDC 8200 CU 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.
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 central unit. The analog output unit features nine XLR-3M audio outputs...
The signals of up to four interpretation channels are available at the outputs AUX OUT 2-3-4-5-6 of the 15-pole sub-D socket. If an SDC 8200 AO analog output unit is connected to the DATA OUT socket of the SDC 8200 CU central unit, additional channels can be output via the analog output unit’s XLR-3M audio outputs.
Connecting several SDC 8200 AO analog output units to the SDC 8200 CU central unit To connect several SDC 8200 AO analog output units to the SDC 8200 CU central unit: Connect the DIGITAL BUS OUT socket of the first SDC 8200 AO to the DIGITAL BUS IN socket of the second SDC 8200 AO, and so on.
Setting up the SDC 8200 system Connecting external equipment to the SDC 8200 AO’s phoenix connector The SDC 8200 AO is fitted with a voltage-free contact (phoenix connector) which turns external equipment (e.g. a recording unit) on and off. When a console is active, the contact is closed and when no console is active, the contact is open.
Setting up the SDC 8200 system Connecting a PC to the central unit If your system comprises interpreter consoles, you require a PC with two serial interfaces: The conference management software accesses the conference configuration via the central unit’s COM 3 interface The interpreter management software accesses the interpreter configuration via the central unit’s COM 1 interface...
