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.
