Notes:
•
If floor distribution is enabled (DIL
switch III-4 off), the floor audio signal
will be distributed on those channels
where the interpretation microphone is
switched off.
•
When interfacing between more than
one LBB 3222/04 interpreter desk and
the infra-red system, or interfacing
between the CCS 400 power supply
and the infra-red system, the floor
distribution should be disabled
(DIL switch III-4 on).
•
Do not use a CCS 400 power supply in
combination with direct connection to
LBB 3222/04 interpreter desks, as this
will cause a fuse to blow.
•
When the Integrus audio input and
interpreters module is used in
combination with audio signals
connected to the cinch inputs of the
Integrus transmitter, the signals on
corresponding channels are mixed.
•
Check the positions of the
DIL-switches before mounting the
LBB 3422/20 Integrus audio input
and interpreters module in an
Integrus transmitter.
