1 6-Channel interpreter desk
Note: Flashing indicators warn that the
with loudspeaker
(LBB 3222/04)
language channel occupied by this desk
is also being used by one or more other
desks.
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.
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.
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.
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.

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 indi-
cators and status ring are ‘on’ when the call-channel
key is pressed. The outgoing language distribution
channel remains occupied by the desk. Not applica-
ble 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.
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 chan-
nel 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.
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 purpos-
es.
17. Outgoing channel-B select keys - 6-way interlock-
ing push-button array to select the outgoing channel
when channel B is selected.
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.
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.
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.

1.3 Rear panel controls
1.4 Interpretation procedures
The rear panel of the interpreter desk contains the fol-
lowing controls and connectors (see figure 1.2).
The original floor language spoken by a delegate is dis-
tributed throughout the conference area, either via a
PA system, or via built-in loudspeaker units on the del-
egates microphone units (both methods may also be
used simultaneously).
This floor language is also distributed to all interpreters
desks, where through their headphone sets the inter-
preters can listen to the floor language to base their
interpretations.
The 6-channel interpretation system is operated com-
pletely independently from the system operator, and is
operated as a stand-alone system only.
The procedures used for interpreting the original floor
language is understood by all interpreters, and where
the floor language is not so well known, two different
operational procedures can be used: normal opera-
tional mode and relay interpretation mode.
Figure 1.2
Rear view of LBB 3222/04
Figure 1.2:
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 connec-
tor (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 con-
nector for connecting a headset (in accordance with
IEC 268-1 1).
6. Message connector - 6-pole female DIN connector
for message function (if required).
•
In the normal operational mode, where the original
floor language is familiar to all interpreters, the
interpreters will listen via their headphone or head-
set to the original floor language. The translations
are then fed to the appropriate channels on the del-
egate’s program selector units or receivers.
•
In a situation where interpreters are unfamiliar with
the floor language (and therefore unable to translate
it), the CCS 800 system has a relay interpretation
facility. This facility allows for an interpreter who is
familiar with the floor language to relay his transla-
tion to other interpreters to which they can base
their own translations.

The configuration of the 6-channel interpreter’s system
is carried out independently of the CCS 800 system.
The controls located under the removable panel on the
desk must be pre-set before putting the system into
operation. To gain access to the controls, remove the
plastic protection cover and text plate located at the
top of the unit. This is achieved by inserting a small
pointed implement into the holes at either side of the
cover and carefully pushing forward to lever it off (see
figure 1.3).

SW 2-1 B-enable - If desks are not to make use of
the B output, the B-enable switch must be
switched ‘on’. The outgoing language distri-
bution channel for each desk will then be
determined by the A-select switch only
(regardless of the position of the A-B channel
selector key on the front panel).
SW 2-2 OR2 enable - To configure an auto-floor
system, the desk from which the transfer
interpretation will be made must have the
OR2 function enabled. The outgoing chan-
nel OR2 indicator will illuminate on this
desk. The B-enable switch must be ‘off’ for
this desk.
SW 2-3 Interlock - To prevent two or more desks
using the same outgoing channel, the inter-
lock feature can be enabled. When this
switch is ‘on’, the microphone will remain
inactive if an occupied outgoing channel is
selected.
SW 2-4 Master / slave - If more than one desk is
installed in a booth, the additional desks
must be set with this switch in the ‘on’-posi-
tion. The first desk in a booth (that nearest
to the IR transmitter) must have this switch
in the ‘off’-position. If only one desk is
installed in the booth, this switch must also
be ‘off’.

The outgoing language distribution channel assigned to
each desk must be pre-set using the A-select 6-position
rotary switch. Each booth should be assigned a differ-
ent channel (1 to 6). The language assigned to each
channel can be written on the removable panel in the
spaces provided alongside the outgoing channel A indi-
cators. The appropriate LED will illuminate to indicate
which language is assigned to a particular desk. Factory
setting: channel 1.

SW 2-5 OR-only - When the OR-only switch is in
the ‘on’-position, the loudspeaker will always
monitor the floor channel. When the OR-
only switch is in the ‘off’-position, the loud-
speaker will automatically switch over to the
OR2 channel when this channel is available.
In the normal operational mode (shown in figure 1.5),
where the original floor language (OR) is familiar to all
interpreters, they will listen to the original floor lan-
guage for interpretation. The translations are then fed
to the appropriate language distribution channels.
In a situation where interpreters are unfamiliar with
the floor language and therefore unable to interpret it,
the system offers an automated relay interpretation
facility (‘auto floor’ - see figure 1.6).
1.6 Auto floor function
An interpreter assigned to translate the floor language,
translates it into another language easily understood by
other interpreters.
The floor language (OR) on all interpreters’ desks will
be replaced by this transfer interpretation. This transfer
interpretation or ‘auto floor’ (OR2) is then used as a
base for further translations.
To cater for circumstances where the original floor lan-
guage is either well known or less well known, two dif-
ferent operational procedures can be utilised.
In the example in figure 1.6, Japanese is the OR and
the auto-floor facility is enabled on the Japanese inter-
preter desk using the set-up selector DIL switch under
the removable panel (the outgoing OR2 indicator is
illuminated on this desk). This interpreter selects outgo-
ing channel B and automatically relays a French trans-
lation as OR2 to all other desks for interpretation and
also feeds the French language distribution channel.
The incoming channel OR2 indicator shows on all
other desks that auto floor is active.

2.2 Configuration
Notes:
Before using the Integrus audio input and interpreters
module, the operation mode must be chosen by setting
the DIL function switches on the module’s circuit
board:
•
If floor distribution is enabled (DIL
switch III-4 off), the floor audio signal
will be distributed on those channels
where the interpretation microphone is
switched off.
•
Select the mode in which the module must operate:
1. As an interface to one or more LBB 3222/04
interpreters desks.
•
When interfacing between more than
one LBB 3222/04 interpreter desk and
the infra-red system, or interfacing
between the CCS 400 power supply
and the infra-red system, the floor
distribution should be disabled
(DIL switch III-4 on).
2. As an interface to other audio sources.
Select if floor distribution (see section 1.6) should
be enabled.
•
1. Enable floor distribution when LBB 3222/04
interpreters desks are directly connected
2. Disable floor distribution when LBB 3222/04
interpreters desks are connected via a CCS 400
system.
•
•
Do not use a CCS 400 power supply in
combination with direct connection to
LBB 3222/04 interpreter desks, as this
will cause a fuse to blow.
•
Select the channels on which the module’s signals
will be distributed.
When the Integrus audio input and
interpreters module is used in
combination with audio signals
connected to the cinch inputs of the
Integrus transmitter, the signals on
corresponding channels are mixed.
Check the positions of the

3 Connecting to an Integrus
Note: To connect the floor signal, a cable
transmitter
with a male XLR connector and a male
cinch connector must be made. See
figure 3.1 and figure 3.2 for the wiring.
3.1 Connecting interpreters desks
LBB 3222/04 directly
An Integrus transmitter requires the LBB 3422/20
Integrus audio input and interpreters module to direct-
ly interface with one or more LBB 3222/04
interpreter desks. This module must be mounted in
the transmitter housing (see the Integrus installation
manual).
Up to 12 interpreter desks can be loop-through con-
nected to the module. The system cable of the first
interpreter desk is connected to the 25-pole sub-D
connector on the Integrus audio input and interpreters
module. The system cables of the next desks are loop-
through connected to the system input plugs on the
preceding desks.
The floor signal for the interpreters desk is connected
to the Aux-Left input of the Integrus transmitter with
an XLR connector. The floor signal can come from a
CCS 800 analogue conference system (i.e. the line out-
put cinch connector, see the CCS 800 installation man-
ual) or from an external audio source, such as an audio
mixer.
Figure 3.1
Connecting one or more LBB 3222/04
interpreter desks directly to the modular
IR transmitter
The DIL switches on the Integrus audio input and
interpreters module must be set to ‘Direct connection
to LBB 3222/04 interpreter desks’ (see section 2.2).
The ‘Aux. Input’ mode of the Integrus transmitter must
be set to ‘Emergency/Mono’ (see the Integrus installa-
tion manual).

3.1.1 Maximum cable length for connecting
interpreters desks LBB 3222/04
The maximum length of the cables to connect the
interpreters desks to the Integrus transmitter depends
on the number of interpreters desks. A leader cable
connects the first interpreters desk to the transmitter.
An extension cable may be needed between the inter-
preters desks. The table below shows the maximum
extension cable length (additional to the standard 3 m
cable) that can be used with different numbers of inter-
preters desks.

3.2 Connecting interpreters desks
LBB 3222/04 via the CCS 400
system
3.3 Connecting other analogue
conference systems
An Integrus transmitter requires the LBB 3422/20
Integrus audio input and interpreters module to
interface with other analogue conference systems.
This module must be mounted in the transmitter
housing (see the Integrus installation manual).
The analogue conference systems are connected direct-
ly to the Integrus audio input and interpreters module
by means of a 25-pole sub-D connecting cable. For
pinning information see chapter 4.
It is also possible to connect a conference system
directly to the Integrus audio cinch inputs of an
Integrus transmitter. In that case the interface module
is not necessary.
An Integrus transmitter requires the LBB 3422/20
Integrus audio input and interpreters module to
interface with the CCS 400 discussion and inter-
pretation system. This module must be mounted in
the transmitter housing (see the Integrus installation
manual).
The CCS 400 system is connected to the Integrus
audio input and interpreters module by means of a 25-
pole sub-D connecting cable. The interpreters desks
and the floor signal are connected to the CCS 400
system. See the CCS 400 installation manual for
more information.
Note: Before connecting the CCS 400
analogue conference systems, the DIL
switches on the Integrus audio input and
interpreters module must be set to
‘Connection to other audio sources’.
For details of the required settings, see
section 2.2.
Notes:
•
Before connecting other analogue
conference systems, the DIL switches
on the Integrus audio input and inter-
preters module must be set to
‘Connection to other audio sources’.
For details of the required settings,
see section 2.2.
•
If galvanic separation is required,
add Beyer type TR/BV3 audio
transformers on the module’s PCB
(see section 2.1).
