3.1.1 Maximum cable length for connecting interpreters desks LBB 3222/0x
The maximum length of the cables to connect the interpreters desks to the Integrus transmitter depends on the number of
interpreters desks. A leader cable connects the first interpreters desk to the transmitter. An extension cable may be needed
between the interpreters desks. The table below shows the maximum extension cable length (additional to the standard 3 m
cable) that can be used with different numbers of interpreters desks.

symmetrical audio input and interpreters module LBB 3422/1x. Such a connection box should be locally made. See Figure 3.3
for the wiring.
