Structuring the SDC 8200 system
44
The three expansion stages
Depending on the number of conference participants, three different
expansion stages are distinguished:
y
Expansion stage (1) comprising one central unit with up to 20 consoles
y
Expansion stage (2) comprising one SDC 8200 CU central unit with up to
120 consoles or one SDC 8200 CU-M central unit with up to 50 consoles
y
Expansion stage (3) comprising several SDC 8200 CU central units with
up to 1024 consoles
Note!
In the following 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.
To make sure that all consoles are supplied with a voltage of at least
30 V, please refer to the chapter “Determining maximum cable
lengths” on page 46.
Expansion stage (1): one central unit with up to 20 consoles
In small conference systems (expansion stage 1), up to 20 conference and
interpretation consoles can be interconnected in one string.
왘
Calculate the maximum cable length using the “Powercalc.exe”
software (see “Determining maximum cable lengths” on page 46) in
order to ensure that all consoles are supplied with sufficient voltage.
