Language Distribution Equipment
10.11.2 Installation
Distribution of the interpreted languages to conference delegates can be distributed by using a wired
or wireless language distribution system.
1. Wired Language Distribution
In a wired distribution system, the interpreted languages are distributed to the delegates via the DCN
system cabling using either table-top delegate units fitted with channel selector units or using the
dedicated Electronic Channel Selector Panel LBB 3524/xx and LBB 3526/10.
Table Top Language Distribution
In a table-top wired distribution system, the interpreted languages are distributed via table top
delegate units, LBB 3531/xx, LBB 3545/00 and LBB 3546/00 and via the chairman unit LBB 3534/xx
and LBB 3547/00. These units include a built-in language channel selector and 1.5-digit LC-display for
selection and viewing of the interpreted languages.

Flush Mounted Language Distribution
The main component in a flush-mounted wired language distribution system is the Electronic Channel
Selector Panel LBB 3524/xx. In fixed installations, the selector panels can be neatly installed into
table-tops or seat armrests, and can be arranged discreetly to follow the delegates’ seating
arrangements.
Interconnection
The Electronic Channel Selector Panels LBB 3524/xx and LBB 3526/10 can be directly connected to
the trunk-line in a loop-through chain, or connected to the trunk-line using a trunk-splitter LBB 4114/
00 or tap-off unit LBB 4115/00.
