1 6-Channel interpreter desk
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 interpreters and relayed as the auto-floor.
The LBB 3222/04 has an integral loudspeaker and is
supplied with a microphone incorporating an illuminated status ring to warn everyone in the booth that the
microphone is active. Two outgoing channels are provided, A and B, switchable by means of a channel
select key.
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 controls) 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.

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

5. Call-channel key - Non-locking push-button to
route the microphone to the call channel for oneway communication with the operator (with priority
over the A/B channel). The microphone status indicators and status ring are ‘on’ when the call-channel
key is pressed. The outgoing language distribution
channel remains occupied by the desk. Not applicable for use with CCS 800 discussion systems.
6. Outgoing message key - Non-locking push-button
to be used for signalling purposes. When pressed,
contacts are closed. This switch is connected to the
6-pole DIN connector for custom wiring.
7. Incoming message indicator - A yellow LED with
1 k W series resistor connected to the 6-pole DIN
connector. To be used for custom signalling purposes.
8. Tone/volume controls - Rotary volume, bass and
treble controls for the headphone.
9. Volume control - Rotary volume control for built-
in loudspeaker.
10. Monitor loudspeaker - Built-in loudspeaker for
monitoring without headphones. The speaker is
only active when the microphone is off.
11. Incoming channel selector - 8-position rotary
switch to select either OR, OR2 or channels 1 to 6
for monitoring as incoming language. This switch is
only active if the incoming channel pre-selector key
is in the ‘up’-position.
12. Incoming channel pre-selector key - 2-position
toggle switch to select either OR when in the
‘down’-position, or the channel selected by the
incoming channel selector knob when in the ‘up’position. If OR is selected and OR2 is activated
using the auto-floor-feature, the desk automatically
receives OR2 for monitoring.
13. Incoming channel OR2 indicator - Green LED to
indicate that OR2 is active instead of OR during
relay interpretation.
14. A-B channel selector key - 2-position toggle
switch for selecting either A or B. If use of channel
B is inhibited, the outgoing channel will be the one
pre-set for the desk by the under-panel A select
control. If channel B is enabled, the outgoing channel can be selected with the channel-B select keys.
15. Outgoing channel-A indicators - 6 green LEDs to
indicate which outgoing channel is assigned to the
desk for channel A using the under-panel controls.
16. Outgoing channel-B indicators - 6 green LEDs to
indicate which outgoing channel is assigned to the
desk for channel B using the outgoing channel-B
select keys.
17. Outgoing channel-B select keys - 6-way interlock-
ing push-button array to select the outgoing channel
when channel B is selected.
18. A-B channel select indicators - 2 red LEDs to
indicate which channel, A or B, is selected.
19. Outgoing OR2 indicator - Green LED to indicate
that the desk is enabled for relaying OR2 to other
desks (using under-panel controls).
20.Engaged channel indicators - 2 yellow LEDs, one
each for A and B, to indicate that the outgoing
channel selected is occupied by one or more desks.
A flashing LED indicates that the outgoing channel
occupied by the desk is also being used by one or
more other desks.
Note: For a full explanation of terms
OR and OR2, see section 1.6.
