2.2 Configuration

Before using the symmetrical audio input and interpreters module, the operation mode must be chosen by setting the DIL
function switches on the module's circuit board:
•
Select the mode in which the module must operate:
1. As an interface to one or more LBB 3222/0x interpreters desks.
2. As an interface to other audio sources.
•
Select if floor distribution (see section 1.6) should be enabled.
1. Enable floor distribution when LBB 3222/0x interpreters desks are directly connected
2. Disable floor distribution when LBB 3222/0x interpreters desks are connected via a CCS 400 system.
•
Select the channels on which the module's signals will be distributed.
The table below lists all the settings:
DIL Switch
I 1,2,3,4,5,6,7,8
II 1,2,3,4,5,6,7,8
III 1,2,3
III 4
III 5
III 6,7,8
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 3222/0x 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 3222/0x interpreter desks, as this will cause a
fuse to blow.
•
When the symmetrical 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 3422/1x interface module in an Integrus transmitter.
