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.

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
ya maximum of 224 interpreter consoles,
ya maximum fo 28 intepreter booths,
ya 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.
