ble in darkened congress venues. The backlighting is
only active when a headphone is connected.
Its up/down select keys provide the delegate with an easy
and reliable means of selecting languages channels.
Channel selection is automatically limited to the number
of language channels available. Until this channel selec-
tor unit is used, i.e. before the language channel selec-
tion or volume control push buttons have been pressed,
there is no output from the unit. This silent function
eliminates noise from headphones not yet in use. When
any of these push buttons is pressed, the unit output is
automatically activated, with floor as a default setting
for the channel selector buttons and the output volume
set to a comfortable level.
The unit can be mounted in three ways:
• directly in table-tops or the arm rests of seats
• into the LBB 3527/00 Channel Selector Housing for Flush
Mounting, which is then mounted in table-tops or the arm
rests of seats
• into the LBB 3525/00 Table-Top Channel Selector Housing,
for use in portable systems or on table-tops.
Note: An unused output cable must be terminated by an
LBB 3518/00 Termination Plug.
