1 6-Channel interpreter desk with loudspeaker (LBB 3222/0x)

1.1 Introduction

The LBB 3222/0x 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 Symmetrical
Audio Input and Interpreters Module (LBB 3422/1x). 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 3222/0x 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: LBB 3222/0x 6-channel interpreter desk

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

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-button 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 integral status indicator ring.

5. Call-channel key - Non-locking push-button to route the microphone to the call channel for one-way 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.

Note: For a full explanation of terms OR and OR2, see section 1.6.

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 interlocking 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 under­panel 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.

1.3 Rear panel controls

The rear panel of the interpreter desk contains the following controls and connectors (see Figure 1.2).

Figure 1.2: Rear view of LBB 3222/0x

1. Headset switch - 2-position slide switch to select either the headset’s microphone or the built-in gooseneck microphone.

2. System cable - 3 m long cable terminated with a 25-pole male D-type connector for connecting the desk to the preceding
desk or to the central.

3. System connector - 25-pole female D-type connector (lockable) for connecting to the next desk.

4. Headphone connector - 6.3 mm jack socket for connecting the headphone.

5. Headset connector - 5-pole female 180° DIN connector for connecting a headset (in accordance with IEC 268-1 1).

6. Message connector - 6-pole female DIN connector for message function (if required).
