with loudspeaker
(LBB 3222/04)

1.1 Introduction

The LBB 3222/04 6-channel interpreter desk provides
listening and speaking facilities for interpreters using
the CCS 800, CCS 400 or non-BOSCH discussion
systems. Up to 12 desks can be connected to an
Integrus transmitter using the Integrus audio input and
interpreters module (LBB 3422/20). It can distribute
up to 6 outgoing languages. An 'auto-floor'-feature is
incorporated for relay interpretation. This allows a less
well-known floor language to be translated by one
interpreter into a language familiar to all other inter-
preters and relayed as the auto-floor.
The LBB 3222/04 has an integral loudspeaker and is
supplied with a microphone incorporating an illuminat-
ed status ring to warn everyone in the booth that the
microphone is active. Two outgoing channels are pro-
vided, A and B, switchable by means of a channel
select key.

Note: Flashing indicators warn that the
language channel occupied by this desk
is also being used by one or more other
desks.

1.2 Front panel controls

The desk has the following front-panel controls and
indicators (see figure 1.1):
Figure 1.1:
1. Microphone activating key - 2-position toggle
switch for activating the microphone. An interlock
facility can be enabled (using the under-panel con-
trols) that prevents the microphone being activated
if the desk's outgoing language distribution channel
is occupied by another desk.
2. Microphone status indicators - Two red LEDs to
indicate that the microphone is active.
3. Microphone mute key - A non-locking push-but-
ton to temporarily mute the microphone. When
pressed, the status indicators and status ring are
'off', but the outgoing language distribution channel
remains occupied by the desk.
4. Microphone - Gooseneck microphone with inte-
gral status indicator ring.
