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 40.
Expansion stage (1): one central unit with up to 15 consoles
In small conference systems (expansion stage 1), up to 15 conference and
interpretation consoles can be interconnected in one string.
The distance between the central unit and the first console must not
exceed 100 m.
Expansion stage (2): one central unit with up to 90 consoles
In conference systems of expansion stage (2), up to six cable strings with
up to 15 consoles each (6 x 15 = 90) can be connected to a single central
unit. This is the maximum number of consoles that can be connected to a
single central unit.
The distance between the central unit and the first console of a cable string
must not exceed 100 m.
