LBB 3547/00
Chairman unit with Channel Selector, Chip-Card Reader
and Graphic LCD Screen
• Graphic LCD screen with backlighting
• Chip-card reader
• Channel selector for accessing interpretations
• Displays messages and conference-related data
• Incorporates all functions of LBB 3546/00 Delegate Unit
This stylish and ergonomically-designed chairman unit
is equipped with all the necessary facilities to enable the
user to function as chairman of a conference. Similar in
appearance to the LBB 3546/00 Delegate Unit, the
LBB 3547/00 Chairman Unit includes a microphone pri-
ority button. When pressed, the priority button causes
all currently active delegate microphones to be tempo-
rarily or permanently switched off, allowing the chair-
man to take control of the meeting. The chairman unit
can also be used to start, stop or suspend voting, cancel
requests to speak, turn off all active microphones and
recall messages for display. A graphic LCD screen with
permanent backlighting can display characters from
complex European languages or icon-based scripts such
as Chinese. Channel selection is automatically limited to
the number of language channels available. The flatpanel
loudspeaker offers superior acoustics with minimal feed-
back, so increasing intelligibility. When the unit is not
being used, the loudspeaker panel conveniently folds
down.
Note: The loudspeaker is not automatically muted when
the microphones are connected.
Note: For information about the pluggable microphones
available for use with this unit, please refer to page 19.
