General information LBB 3520/00
The interpreter desk has two functional
modes: operational mode and programming
mode. In the operational mode the interpreter
desk is divided into two main working
sections: the listening section and the speaking
section. The listening section provides
headphone and loudspeaker monitoring
facilities to listen to the floor or other
translations.The speech section provides
controls for the outgoing translation channels.
In its programming mode, operational
functions can be set before a discussion
begins.The programming mode (under a
menu driven display) enables audio channels
to be assigned to specific languages, the
selection of the interpreters A and B output
translations, as well as providing an override
and interlock facility between booths.
Instructions for use

Each interpreter desk includes a Relay select
rotary switch for selection of the incoming

assigned to the interpreters three most
familiar or working languages.The incoming
language is displayed on the units
alphanumeric display together with a quality
indication, providing the interpreter with an at
a glance indication of the quality of the
incoming language .The quality indication
displays whether the incoming language is
direct from the floor speaker (FLOOR) or
whether its a translation of the floor language
(+) or whether its a translation of a translation
of the floor language (-).
Monitoring the incoming languages is done via

9.3 Outgoing channel control
(Speaking)
To distribute the translation, the desk provides
two outputs, output A and output B. Output
A is a preset output used for the interpreter's
normal outgoing output, and output B (if
selected during programming) is used for
translating from less common languages, or as
a second outgoing language output where
different languages are to be distributed from
the same desk.
Selection of the A or B outputs is by means of
two push-buttons marked A and B (fig.10
