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.

and interpreters module  
(LBB 3422/20)  
2.1 Introduction  
An Integrus audio input and interpreters module is  
required when an Integrus transmitter is to be used for  
direct connection of interpreters desks LBB 3222/04  
(in combination with e.g. the CCS 800 system) or with  
analogue conference systems (such as the CCS 400).  
The interface module must be mounted in the trans-  
mitter housing.

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).
