1.1 Contribution equipment
Contribution equipment describes the units which participants use to contribute to a conference.
Depending on the type of contribution unit, delegates can access the DCN’s wide range of facilities to
listen, speak, register a request-to-speak, receive screen messages, communicate with other delegates
via an intercom and to participate in electronic voting sessions. On insertion of an ID-card dedicated
software is required giving much more facilities.
Chapter 1. Introduction Digital
Congress Network
(DCN)
The BOSCH Digital Network System (DCN) provides flexible control facilities for all types of
conferences from small discussion groups to international, multi-lingual congresses with hundreds of
delegates. Facilities range from basic microphone management, to delegate identification and
registration, electronic voting, information distribution and display, up to extensive simultaneous
interpretations and automatic camera control.A single operator using a computer with DCN’s
application software can control even the largest of congresses. Systems can be expanded by adding
more contribution equipment and introducing PC control with DCN’s application software.
2
Contribution units can be used free-standing on a table-top, or flush-mounted in desks, seat backs or
armrests. Other microphone types such as lavalier and hand-held are also available, allowing
contribution from non seated participants such as a guest speaker for example.
1.2 Central Control Equipment
The Central Control Unit (CCU) forms the heart of the DCN system.The CCU can operate stand-
alone to provide automatic conference control, or it can be accessed by an operator via a personal
computer (PC) when more extensive management control is required.
The full range of DCN equipment includes:
1. Contribution equipment
2. Central control equipment
3. Simultaneous interpretation and language distribution equipment
4. Information display equipment
All CCU’s can control up to 240 contribution units. If more capacity is required, slave CCU’s can be
connected, each of which increases the system capacity by 240 contribution units.A maximum of 16
slave CCU’s can be connected to a system. Other extension units include an Extension Power Supply
unit and an Audio Media Interface unit which extend the systems power handling capacity.
5. Application software packages
6. Installation equipment
The CCU offers basic microphone management, simultaneous interpretation and electronic voting
facilities, as well as digital audio channels, data channels and communication channels.This allows
effective unsupervised control of even large or international conferences. The extended CCU offers
all the facilities of the basic CCU, but allows operator control via a personal computer (PC).The
operator can access the wide range of DCN application software packages, each with a specific
function in controlling and monitoring conferences.This includes advanced simultaneous
interpretation and microphone management, message generation and display, voting procedures,
intercom, creating a delegate data base, attendance registration, audio processing and automatic
camera control.
DCN equipment is also complemented by external equipment such as video and character displays,
TV cameras, personal computers, monitors, PA amplifiers, loudspeakers and printers all of which are
fully compatible and easily integrated into the DCN system.

1.5 Application software packages
A comprehensive range of software packages is available for use with centrally controlled PC-systems.
These packages run under Microsoft® Windows® integrate conference preparation management
and control into this versatile graphical computer environment.Any combination of packages can be
down-loaded according to specific system requirements. DCN software packages are generally used
in larger scale systems where operator control is required.
Interpretation.
2
Using the same trunk-line cabling DCN’s interpreter desks can easily be integrated into existing
systems, offering comprehensive facilities for simultaneous interpretation.The desk can accommodate
up to 15 different language channels, plus the original floor language. A maximum of six desks can be
installed per interpreter booth.They can be used stand-alone or as part of a more comprehensive
system.When used stand-alone, the units built-in microprocessor is manually programmed to allocate
language channels, channel routing and interlocks. In PC operator-controlled systems, the desk is used
in combination with DCN dedicated software, and other interpreter desks (if required) to form a
completely integrated interpretation network.An in-built facility enables direct or auto-relay
interpretation to cater for less well known languages. Each desk has two output channels, one for the
normal interpretation and one for second or auto-relay translation.
The PC running the software is connected to the DCN system and therefore has direct
communication links with contribution, interpretation and control equipment via the systems trunk-
line data bus or the CCU’s serial communication port.Therefore all aspects of conference
management can be brought to a single point of control, Leading to increased ease of use, efficiency
and data distribution.

Language Distribution
Distribution of languages to individual delegates can be by wired or wireless language distribution
systems.A wired language distribution system uses delegate contribution units that include a language
channel selector, or dedicated language channel selector units. A wireless language distribution system
uses the Infra-red transmission technique.
1.4 Information display equipment
The DCN system can distribute information to conference participants quickly and efficiently to suit
all requirements.A wide range of displays are supported from simple LCD personal screens to video
equipment for venue broadcasting.
The chairman unit, interpreter desk and one type of the delegate unit is equipped with a graphic
(chairman, delegate) or alphanumeric (interpreter) LC-display which displays delegate information,
voting results and operational procedures, public and personal messages, microphone status and
multi-lingual user instructions.
Hall displays can quickly display conference information to a large number of conference participants.
Numeric, alphanumeric or geographical displays are available, to display voting results. TV receivers
andVideo Displays allow high quality display of any live or recorded material, computer-generated
graphics, text, and information generated by DCN software.

1.6 Installation equipment.
PC-bus
ACN 1
Fast cost-saving installation is an important benefit of the DCN’s digital technology.A thin twin-coaxial
cable carries all the system’s digital signals, eliminating the need for the costly and vulnerable multi-
core cables used in conventional analogue installations.The same cable is used to transport the signals
to all delegates’ microphone units throughout the system and can be ‘tapped off’ at any desired point
to connect the microphone units or any system unit associated with the DCN system. Later capacity
extensions - for example to add extra microphone units does not demand changes to the system
cabling.All that is needed is to connect the required DCN system units or branches to the installed
cabling.Trunk-line splitters and extension cable assemblies are available to simplify installations in

Communication through the Network cabling and all units connected to it, is done using three
dedicated digital communication IC’s,ACN 1,ACN 2 and ACN 3. Units that include an ACN 1
microprocessor - such as the delegate unit, chairman unit and interpreter desk - communicate to the
Central Control Unit, via the units ACN 2 microprocessor on a send and receive basis (active or
passive). Units that include an ACN 3 microprocessor - such as the Channel selector units - receive
information on a receive basis only, such units are known as passive units.

1.7 Quick reference to DCN’s functions
1.8 DCN Software packages
Stand-alone System
1.8.1 Microphone Management software
Microphone management software provides a text-based solution (delegates’ names) for managing
delegates’ microphones. Run under Windows® the operator controls the delegates’ microphone
operations through menus.
A discussion system; delegates control their own microphone actions - without the need of a non-
participating operator. Discussion systems cater for smaller groups, although the number of delegates
can be extended to the total capacity of the DCN system.A discussion system therefore is ideal for
small meeting halls, boardrooms, and hotels etc. where clear and concise speech intelligibility through
sound amplification is required.
2
The Microphone Management software offers five modes of microphone control:
•
•
•
•
Operator with *Request-to-speak list (MANUAL)
Operator with *Request and **Response list
Delegate with *Request-to-speak list (OPEN)
Delegate control with override (of other delegates’ microphones)
*A Request-to-speak list is a list of delegates waiting to speak.To join the list delegates first press
their microphone keys. If the maximum number of delegates are already speaking the delegates
then joins the list. The number of delegates allowed to speak at the same time is set to 1,2,3, or
4.
PC Controlled System
Delegates’ microphone actions are controlled by a none participating operator using a personal
computer.
Microphone Management
Method by which delegates/operator control the microphone units. Microphone Management
control therefore is needed in order to conduct civilised and disciplined discussions/conferences.
** A response list is a list of delegates that need to react immediately to a current speaker.
Response requests are positioned at the top of the request list.
Delegate withVoice activation
The DCN system has its own built-in standard microphone control functions.These functions are
usually sufficient for use in discussion groups using a stand-alone system. In conference systems
however a central PC operator has extended microphone management capabilities when using
DCN’s dedicated microphone management software.
•
REFERENCE: For more information refer to the LBB 3570 software manual
Microphone Management Operation Modes:
1.8.2 Synoptic Microphone Control
Synoptic microphone control software provides a graphical solution using pictograms of microphone
units. Run underWindows® the operator controls microphone units by simply pointing and clicking a
mouse on the desired unit. Synoptic microphone control is icon based. It relies on the location of
seats and uses pictograms that show icons with seat numbers or with names.
OPEN (AUTO)
The OPEN mode allows up to 1, 2 or 4 delegates (Active Micros) to control the on/off state of
their own microphones unit simultaneously without the use of operator intervention.When more
than the number of Active Micros has been reached, delegates requesting to speak join a request-
to-speak list.
REFERENCE: For more information refer to the LBB 3571 software manual
1.8.3 Simultaneous Interpretation
OVERRIDE (First-In-First-Out)
Interpretation is the term used where the language of the floor speaker is interpreted by interpreters
using interpreter desks into the languages of the other conference participants.
REFERENCE: For more information refer to the LBB 3572 software manual
The Override mode allows up to 1, 2 or 4 delegates to speak on a FIRST-IN FIRST-OUT basis i.e
Override.With the override mode, their is no request-to-speak list, only the pre-selected number
of Active Micro’s may be switched on simultaneously.This means that if another delegate should
switch on his microphone unit, the microphone of the first delegate having joined the group will
be switched off, allowing the latest delegate to join in the discussion.
VOICE ACTIVATION
The ‘Voice’ activation mode is an automatic method for activating the microphones of the dele-
gate and chairman units by voice.The maximum number of voice activated units available for
selection in a stand-alone system is 2 or 4.This mode of operation is intended for free discussion
amongst participating delegates. For enhanced operation an additional Public Address system is
highly recommended.

2.1.4 ‘Microphone Only’ Function
For use by delegates to actively participate in discussion/conference proceedings - ranging from small
discussion groups to multi-national conferences. Its basic functions allow delegates to speak, listen to
other participants, and to participate in voting sessions (conference units only) using the units voting
keys .
A microphone‘only’ function is for use by Podium and mobile floor speakers, or in installations where
no delegate units are used. DCNs range of microphones can be connected to a Dual Audio Interface
unit or a Multi-purpose connection unit.The Dual Audio Interface unit LBB 3535/00 can serve two
delegate positions.

2.1.3 Chairman unit
2.1.5 Interpreter desk
For use by a chairman, the chairmans unit is similar to the delegate unit but includes a‘priority button’.
This button when pressed temporarily mutes or permanently cancels all other microphone users.An
optional chime tone is available when the priority button is used. A system may have one or more
chairman units; for use by assigned delegates, privileged speakers orVIP’s etc. In permanent mode, all
delegates waiting to speak are also removed from the request-list. Chairman unit LBB 3547/00 has
five soft-keys that enable the chairman to control, initiate, and to participate in voting sessions, as well
as to cancel all delegates’ microphones and requests-to-speak.
For use in bi/multi-lingual discussions/conferences, the interpreter desks can handle up to 15 different
language channels in addition to the floor language. Up to six interpreter desks can be installed per
booth. Its design provides for efficient operation, and preselection of the incoming language. A back-
lit alphanumeric display shows the selected language in combination with a ‘quality indication’ (direct
or indirect interpretation).An ‘auto-relay’ facility enables interpreters to interpret from unfamiliar
languages, where the desk automatically transmits the relay language to all other interpreter desks for
onward interpretation.

In portable systems, discussion units can be free-standing on a level surface - such as a table-top. In
permanent installations, the units can be nut/bolt mounted using the 2 x M3 threaded holes under the
unit. In such an installation, the units cable securing clamp can be removed from its cable entry and
modified, allowing its 2 m cable to be neatly run through a hole directly under the table-top surface
(see opposite). For cable clamp modification, remove the cable clamp at the rear of the unit by
unscrewing the clamps two securing screws (A) . Once removed, use a sharp cutting tool to remove
the small insert (B) from its housing. Run the units cable through the cable run and secure it into the
free cable entry using the removed insert (B) as shown in (D).

Digital Congress Network | Installation and Operating Manual | Chapter 3 - Interpretation Equipment
Chapter 3. Interpretation
Equipment
The DCN system offers comprehensive facilities for simultaneous interpretation and distribution of
the interpreted languages to delegates, allowing the system to meet all the demands of international
conference and congress venues.All interpretation facilities are fully integrated in the basic system
concept, with digital distribution of the language signals using the same cabling as all the other system
functions.
2
3.1 LBB 3520/10 Interpreter desk with back-lighting
LC-display
The interpreter desks provides each interpreter with all the necessary facilities according to
internationally agreed standards.The microprocessor controlled desk (A-B type) can handle up to 15
different language channels plus the original floor language. Up to six desks can be fitted per booth.
The desk includes an intercom facility where an intercom handset can be mounted for two-way vocal
communication between interpreters, the chairman and delegates.
Being microprocessor controlled, with a built-in LC-display, the desk in stand-alone systems can be
programmed manually, to preset the allocation of the language channels, channel distribution, and
interlocks. In PC operator controlled systems the desk in combination with dedicated software can be
programmed by the operator to set all functional interlocks and channel allocation parameters.
An innovative function of the interpreter desk is its three personal incoming language pre-select keys.
Instead of having to manually select from all the available channels, the interpreter can quickly pre-
select the three incoming languages which are most relevant as well as the floor language.This allows
quick, secure switching between the preferred languages and reduces the chance of operating errors.
The alphanumeric display gives an at-a-glance indication of the selected language in plain text form.A
further refinement is an indication of the ‘quality level’ of the incoming channels. Up to now,
interpreters often had no way of knowing if they were receiving a direct or an indirect interpretation.
This facility gives them the option of avoiding the use of an INDIRECT interpretation if a DIRECT
interpretation is available in a language which is known to the interpreter.
The desk also provides for convenient transfer or relay interpretation, to enable the handling of
‘exotic’ languages for which sufficient qualified interpreters are not available. In this case, the DCN’s
unique auto-relay function automatically transmits the relay language to all the other interpreter desks
FIG 3-1 Interpreter desk LBB 3520/10
for onward interpretation.

4.1 Introduction Central control equipment
The Central Control Unit (CCU) is at the heart of the DCN system, and has control facilities for up
to 240 contribution units, such as delegate and chairman units, interpreter desks, as well as audio and
multipurpose interface units.The CCU can function with or without a central operator using a PC.
Stand-alone systems
For use in smaller systems where an operator is not essential, the Central Control Unit type
LBB 3500/05 is used as a ‘stand-alone’ unit providing basic microphone operational modes, basic
parliamentary voting procedures, and facilities for organizing interpretation channels and basic
intercom functions. A dedicated RS 232 port is used for automatic camera control (default) and can
also be set for ‘test and diagnostic’ purposes.
LBB 3500/35 and LBB 3500/35(D)
PC control
For use in larger systems requiring a central operator, Central Control Units type LBB 3500/15 and
LBB 3500/35 are used allowing a PC to be used as the interface between an operator and the DCN

4.9 CCU Audio Routing Modes
To provide additional functionality in the CCU, the DCN software from release version 7.01 includes
two new ‘Audio Routing’ modes - ‘MIX-MINUS’ and ‘INSERTION’ mode. Both modes are selected by
setting DIP-switches (S9) on theTCB4 card located in the Central Control Unit CCU (see Chapter
4.5.2).
To set the CCU for the Mix-Minus mode Dip-switch ‘S9’ on theTrunk
Communication Board must be set as follows:

In the‘INSERTION’ mode, the normal audio routing path in the CCU from added microphone signals
to the loudspeakers of the delegate and chairman units is interrupted to allow connection of an
external device for example - an audio mixer. The external audio device is connected between the
‘Line-Output’ and ‘Line-Input’ of the CCU.

6.1
Allegiant Video Switcher
To provide‘DCN’Automatic Camera Control AllegiantVideo switchers (FIG 6-1) and their associated
equipment are used. For use in DCN stand-alone or PC operator controlled systems, theVideo
switcher in combination with the relevant software modules allows video cameras to be configured
for switching and directing towards speaking conference participants (i.e. delegates, chairman etc.) for
display on monitor screens.
6.1.1 Allegiant Switcher Control Keyboards
At least one keyboard is required for manual control and programming of the Allegiant switcher.
Using the keyboard enables camera preset positions to be defined, manual override of automatic
positions and picture selection.The recommended control keyboard is the LTC 8555 with variable
speed joystick and reduced size.
software and programmable via a combination of the Allegiant keyboard and DCN GUI software
modules for DACC in Stand-alone and PC-controlled systems. The maximum number of video inputs
supported by the DCN software is 256.
6.1.2 Cameras and Monitors
A combination of fixed and orientable cameras with remote positioning and zoom lenses are available
for connection to the video switcher.The maximum number being dependent on the number of
available video inputs. Colour cameras are preferred, providing composite video outputs according to
the PAL B and NTSC standards.
The following table gives the range of applicable AllegiantVideo Switchers.

Orientable cameras must accept bi-phase control signals as generated by the Allegiant video
switchers. Upon start up, when no microphones are activated or during camera movement from one
position to the next (if enabled in the software) an “overview” picture is shown on the connected
video displays (e.g. monitors, large screenTV’s, video projectors).This picture is provided by the
“overview” camera (fixed (preferred) or orientable) which is always connected to video input No.1. If
an orientable camera is used (preferred type ‘AutoDome’ system) the highest available preposition is
used (software dependent).

NOTE: For preferred camera types, both fixed and orientable, refer to the DCN Confer-
ence and Discussion Systems Data catalogue.
TheVideo Switcher series LTC8200 for example provides 16 camera inputs, and 5 monitor outputs.
Using theVideo switchers signal distribution ports, connection to on-site receiver/drivers
(AutoDome™ camera’s with pan/tilt motors), provide operator control of pan, tilt, zoom, multiple
pre-fix positions, four auxiliaries, auto-pan and random scan.
Video displays, accepting composite video signals according to PAL B or NTSC standard are required
for showing the picture to the operator and audience.A 14” or 17” monitor for the operator with
high or at least medium video performance is preferred.This monitor must always be connected to
video output No.1 of the used video switcher. For preferred monitor types refer to the DCN
Conference & Discussion Systems Data catalogue.

A maximum of 4 audience video displays can be connected to the Allegiant video switcher (not
applicable for video switcher LTC 8100 series) using outputs 2 to 5.The actual number set is defined
in the DCN Camera Control software LBB 3562 or LBB 3588.This option may save the need to use
a video distribution amplifier. Use of more than one video output for the audience may have a
negative influence on the system performance (response to events) for camera control.

6.3 Switching options using a personal computer
Key to symbols
Using the communication port (COM-port 2) of a PC, a wide variety of communication and
switching options are available. For example, video cameras can be switched and directed towards
speaking delegates when aVCS (Video Control Switcher) is connected to the PC. Using DCN’s
Microphone Management software LBB 3570, and/or Synoptic Microphone Management software
LBB 3571, cameras can be switched corresponding to the status of delegates’ microphone actions.
Directing a camera towards a speaking delegate is done using motor driven pan/tilt equipment,
programmed and linked according to the microphone activity function which can be activated within
the mentioned software packages.

LBB 3512/00 Data Distribution Board
Chapter 8. Information
The data distribution board provides the communication interface between the DCN system and
externally connected peripheral equipment - such as hall displays, remote switching panels and
tailored conference solutions.The board is intended for mounting in the relevant equipment and
includes an RS232 communication port with a baud rate of 9600 and 19200 baud - selectable by an
on-board dip switch.The board can be powered by the system itself or from an external power
source.
Displays
2
Hall displays enable conference information to be clearly and effectively displayed to a large number
of conference participants. Numeric, alphanumeric and geographical displays are available, and mainly
used for displaying voting results and other text and conference related data. Also direct view or
front and rear projector video displays can be used e.g.TV receivers,Video projectors for long
distance viewing
Interconnection between the board and the DCN system is via a 6-pole circular connector.The board
has no system loop-through facility, therefore aTrunk-splitter LBB 4114/00 orTap-off unit LBB 4115/
00 is used to bypass the board in a loop-through configuration.
In order to drive a hall displays, a data distribution board LBB 3512 must be installed in the display.The
board includes an RS232 communication port with a baud rate of 9600 or 19200 baud selectable by
an on-board dip-switch. Opto couplers isolate it from the DCN system. It can be powered from the
DCN system or an external power source.
The board can be used as either a passive unit for reception of data , or as an active unit for
transmission of data to the CCU.

10.1 Introduction Installation Techniques
Chapter 10. Installation
Techniques
The primary focus of this chapter is to provide system installation techniques, typical examples, and
system limitations for stand-alone and PC- controlled systems using the range of equipment described
in Chapter 2..

The cable attached to each DCN unit forms the trunk-line cabling (‘daisy-chain’).This cable carries all
the systems digital signals, up-down links and power supplies. Its versatility allows units to be‘tapped-
off’ anywhere throughout an installation, meaning that systems can easily be expanded without the
need to change the system cabling. The single cable handles as many as 16 up and 16 down high
quality contribution, distribution and data channels or 15 up and 15 down plus four speech-quality
intercom channels.
Installation is simplified by the use of ready-made cables, and where needed trunk-line splitters and
Tap-off units.
REMARK: Before attempting to install a DCN system read the following Chapter 10.1.1,
‘System design fundamentals’ .This chapter introduces the reader to DCNs power handling
requirements and its control limitations.
10.1.1 System design fundamentals
The total number of system units in any installation is limited by the maximum power handling
capacity and control capacity of the CCU (as well as the current consumed by individual system
units). Because each DCN unit is a current consuming device, each unit draws a certain amount of
current, depending on its power consumption requirements.This value normally expressed in Watts
has been simplified to help make the total power handling capacity of a system easier to calculate.
To overcome the limitations of a system, dedicated units with extension facilities are available to
extend the systems power handling capabilities. Such units include an Extension Power Supply Unit
LBB 4106/00 and an Audio Media Interface Unit LBB 3508/00. Where more than 240 units are
required, the system offers a Multi Central Control Unit (Multi-CCU) configuration (See Chapter 4.4
for more information)

10.2 Power Handling Capacity
To understand the power handling capacity of a system, individual DCN units have been assigned with
LBB 3500/xx Central Control Unit
LBB 3508/00 Audio Media Interface Unit
a Power Consumption Factor (PCF). The PCF therefore has a bearing on the total number of units
that can be connected to a system.The maximum number of units, quoted for a CCU is based on all
units having a PCF of 1.This means for example, that a CCU can accommodate 60 units of PCF (valid
for each trunk/tap-off output), but can also accommodate 120 units of PCF 0.5. Table No. 10.1 gives
the PCF value rated for each DCN system unit.
The length of (extension) cable used also has an influence on the number of units connected to a
system. Therefore to calculate the PCF value in relation to the length of cable used, a calculation
graph has been devised (refer to Chapter 10.4 “Calculating the PCF of a system”).

Calculation Method
10.4 Calculating the PCF of a System with respect to cable
length
As stated, the length of cable used in a system has a direct influence on the PCF of a system. In the
example shown in FIG 10-7, the second in-line trunk-splitter has two extension cables connected to
it, with lengths of 20 m (65.6 ft.) and 50 m (164 ft.) When determining the cable length of a trunk-
outlet or tap-off connector, the longest extesion cable only is taken in to account - in this example,
the 50 m (164 ft.) cable.Therefore, in this example the total extension cable length from a single
trunk-outlet of the CCU is calculated as 20 (65.6)+10 (32) +50 (164)= 80 m (262 ft.).
•
Using the PCF table (Table 10.1) and the graph (FIG 10-10) calculate the PCF value required for
the system. If the PCF value exceeds 60, then more than one of the CCU’sTrunk outlets must
be used.
•
•
Calculate the length of the cable for eachTrunk outlet. “Maximum cable lengths usingTrunk
outlets andTap-offs” when attaining the length of an extension cable.
A unit with a regenerative tap-off should be placed every 100 m (328 ft.).This length includes
the 2 m (6.5 ft.) cable length of each attached unit.

1. Using the graph, check for each CCU outlet that the cross-over point according to the extension
cable length and the PCF value is within the approved system limits.The approved system limits
are defined by the grey shaded area of the graph.

NOTES:
1. If only one CCUTrunk outlet is needed, step 2 is not applicable.
2. An Microsoft Excel based DCN calculation tool for use on a PC is available on request.
2. Using the data obtained in step 1, (i.e. the PCF value and the length of extension cable) use the
cable correction graph to calculate the PCF value for the relevantTrunk outlets.The PCF values
with cable correction are shown within small white squares. Once done add the PCF value for
each trunk-line.This summed total gives the system PCF value.

NOTE:
This method of calculation is used for all units withTrunk outlets andTap-offs
The maximum PCF capacities are:
•
•
•
•
•
60 PCF for each of theTrunk outlets andTap-offs
90 PCF in total for the LBB 3500/05 Central Control unit
180 PCF in total for the LBB 3500/15 and LBB 3500/35 Central Control unit

180 PCF in total for the LBB 4106/00 Extension Power Supply unit
10 m (32.8 ft.)
20 m (65.6 ft.)
50 m (164 ft.)
When usingTrunk-splitters orTap-off units,their PCF must also be taken into account
(see PCFTable 1).
EXAMPLE:
These examples are based on the system configurations shown in FIG 10-8 and FIG 10-9. These
configurations show two systems using all three trunk-line connectors.
FIG 10-7 Calculating the length of extension cables
1. Using the graph shown (FIG 10-10) check that each trunk-line in use is within the approved sys-
tem limits (i.e. within the grey shaded area).
2. Using the PCF extension cable correction graph, locate the PCF value on the ‘Y’ axis, that are be
connected to the trunk-line. On the ‘X’ axis, locate the length of extension cable needed. Using
standard graph reading procedures join the two together to obtain the PCF value including exten-
sion cable length correction.The actual PCF value is shown within small shaded squares.
Table No.10.2 gives the PCF value for the example shown in FIG 10-8
Table No.10.3 gives the PCF value for the example shown in FIG 10-9
Before calculating the PCF of a system, consider the following:
•
•
How many units will be connected, and what is their total PCF value?
What is the total length of cables used per CCU trunk-outlet, and what is the total length of
extension cable used on this trunk-outlet?

10.5 Control Capacity
10.6 Stand-alone Systems
The Central Control Unit LBB 3500/05 has a power handling capacity to power up to 90 DCN units,
while Central Control Units LBB 3500/15 and LBB 3500/35 have a power handling capacity to power
up to 180 DCN units. However, the built-in‘control facilities’ of all CCUs are capable of controlling up
to a maximum of 240 active units* and an unlimited number of passive units**. A combination of
both active and passive units can be connected to any system ‘tap-off’ or trunk-line outlet connector.
(using Extension cables, Trunk-splitter andTap-off units)
All DCN system units are connected to the CCU via its three outlet trunk-line cable connectors.
2
10.6.1 Basic System (without extension units)
Where more than 240 active units are required, the DCN system can be extended with the Multi-
Central Control unit LBB 3500/35 for use in Multi-CCU systems. In combination with a dedicated PC,
fitted with a Multi-PC- card LBB 3511/00 and Multi-CCU software LBB 3586/00, the PC can control
up to a maximum of 16 CCU’s connected in a 75 ohm coaxial loop-through chain. Each CCU in the
chain has the same Power handling and control capacity as the Extended CCU (LBB 3500/15).
In total, a maximum of 3,840 active units, using sixteen LBB 3500/35 type CCU’s can be controlled.
FIG 10-13 shows a basic trunk-line interconnection, without extension units.

IMPORTANT: When using the DIRECT connection method between the Control PC
and the CCU, the central operator has NO facilities on the PC for using headphones or an
intercom handset. Additional DCN units are then required to provide these functions.
IN-DIRECT
LBB 4114/00
IN-DIRECT connection see FIG 10-17). Using this method, a Network card LBB 3510/00 (see
Chapter 5.2) is installed in the central control PC. Using the cable supplied with the Network card
LBB 3510/00, connect the 15-pole D-type connector to the 15-pole D-type socket located on the
PC Network card, and connect the DCN 6-pole modular connector to the DCN trunk-line Cabling.

carried by delegates.A well balanced installation should be based on sufficient direct radiation
intensity for the area to be covered. Each situation demands its own solution to maintain a high
enough signal-to-noise ratio in order to ensure good clear reception within the conference area.
Optimally positioned radiators will both minimize installation and running costs.
10.11.1 Introduction
Distribution of interpreted languages to delegates can be handled using two different methods of
language distribution - Wired and Wireless.
2
1. Wired
For further detailed information on installing an Integrus digital infra red system, particularly on
positioning radiators and operating the system, refer to the Infra-red Language Distribution Systems
Installation and Operating Instructions manual, Code No. 3122 475 2201x.
The distribution of interpreted languages through language channels can be handled using the
standard DCN system cabling. Delegates with contribution units fitted with channel selection facilities
can listen to the language channel of their choice. Stand-alone channel selector units type LBB 3524/
xx and LBB 3526/10 are available for use in both portable and fixed installations. In fixed installations
the channel selector units can be installed in to table-tops or armrests.
2. Wireless
For those delegates with no access to a channel selector, an infra-red wireless distribution system can
be used. Using this system infra-red signals carrying language channels are transmitted from wall or
ceiling mounted radiators, and received by delegates using personal infra-red receiver units.
The infra-red language distribution system comprises of an IR transmitter, a Multi-channel Audio
Interface Unit LBB 3423, one or more radiators and personal IR receivers with channel selectors for
selection of the required language channel.

10.11.2 Installation
The main component in a flush-mounted wired language distribution system is the Electronic Channel
Selector Panel LBB 3524/xx. In fixed installations, the selector panels can be neatly installed into
table-tops or seat armrests, and can be arranged discreetly to follow the delegates’ seating
arrangements.
Distribution of the interpreted languages to conference delegates can be distributed by using a wired
or wireless language distribution system.
1. Wired Language Distribution
2
In a wired distribution system, the interpreted languages are distributed to the delegates via the DCN
system cabling using either table-top delegate units fitted with channel selector units or using the
dedicated Electronic Channel Selector Panel LBB 3524/xx and LBB 3526/10.
Interconnection
The Electronic Channel Selector Panels LBB 3524/xx and LBB 3526/10 can be directly connected to
the trunk-line in a loop-through chain, or connected to the trunk-line using a trunk-splitter LBB 4114/
00 or tap-off unit LBB 4115/00.
Table Top Language Distribution
In a table-top wired distribution system, the interpreted languages are distributed via table top
delegate units, LBB 3531/xx, LBB 3545/00 and LBB 3546/00 and via the chairman unit LBB 3534/xx
and LBB 3547/00. These units include a built-in language channel selector and 1.5-digit LC-display for
selection and viewing of the interpreted languages.

System
When all the units in a system have been installed, the system must be initialized and made ready for
use.The initialization procedure enables all DCN units installed to be recognized by the CCU.
Recognition is given in the form of an address, allocated by the CCU to each active unit in the system.
A ‘de-init’ switch located under each DCN contribution unit is used to clear the units allocated
address when conflicts with duplicated addresses occur.

11.1.1 Initializing a stand-alone system (FIG 11-1)
Note: Step 1 is normally not required for systems powered-up for the first time. First-time systems
are de-initialized, therefore proceed with step 3 after switching on the CCU for the first-time.
STEP 1. On the CCU locate the push-button and the small recessed switch (Start) under‘Equal-
izer’. Using a small pointed device (e.g. paper-clip) insert the device into the recess hole
(3) and activate the switch while holding down the equalizer ‘Start’ switch and ‘Equal-
izer’ push-button for at least 10 seconds after switching on the CCU (1). Ensure its
power LED is lit. (2). DCN units with LC-display show the firmware release version of
the unit itself and not the CCU firmware release version
FIG 11-1 De-initializing CCU
11.1.2 Initializing a PC-based system
The clearing of addresses and the initialization procedure for systems using a PC is identical to that of
a Stand-alone system. However by using DCN’s System Installation Software LBB 3585/00, seat
numbers can be linked to units that have already been initialized.
Bosch Security Systems B.V.
Release : x : xx
Using Software package LBB 3585, two methods are available for linking active units to seat numbers/
names:
STEP 2. All unit addresses have been cleared and the LEDs on all active units illuminate after com-
pleting step 1. NOTE: If this is not the case resume at step 1 again or remove the unit.

From the hall, by physically pressing delegate unit microphone buttons in sequence. Each
microphone unit is then registered by the PC which in turn automatically links a unit to a
specific seat number.
STEP 3. To initialize an individual unit press the units microphone key while the units LEDs are lit
(for interpreters desk press the ‘Mute’ key, the Dual Audio Interface Unit and the Multi-
Purpose Connection have their own ‘de-init’ , but can also be initialized by pressing the
microphone key of a connected microphone). Once pressed the units LEDs go out.The
unit is now recognized in the system by the CCU. Repeat this procedure for all active
units installed in the system one by one. Initialize all units one by one (not simulta-
neously) to eliminate addressing problems.
b.
From the PC, where the operator simply selects a microphone unit. This unit is then linked to
a specific seat number. From this selected seat number the PC assigns the next microphone
unit in sequence.This sequence is according to the initialization process.
STEP 4. To clear the individual address of a delegate/chairman unit in the event of an address
conflict, press the ‘DE-INIT’ switch of the relevant unit (see Chapter 2.).
The Dual Audio Interface unit can be linked to two seat numbers even though the CCU during
initialization assigns it with a single address.

REMARKS:
11.5 Sound Management
1.The frequency response of a room is dependent on the position of microphone and loud-
speaker used, particularly if a microphone is relative close to a loudspeaker. Switching
between a microphone-loudspeaker combination and another can result in an entire
different frequency response.Therefore, equalization has primarily an advantage if the
microphone is in the diffuse field of the loudspeaker, for example if a separate PA sys-
tem is used.
11.5.1 Equalizer function
To produce optimum speech intelligibility for a particular discussion room or conference hall the CCU
includes a built-in system audio equalization facility.This facility automatically sets the overall audio
characteristics of the DCN unit loudspeakers. (see fig 11-2 9(3)).
2
2.The equalizer is only active on the delegate loudspeaker channel and the equalized PA
output.The equalized PA output is only available on the Audio Media Interface LBB
3508/00, channel 12.
NOTE: Channels 12 (line-output) and channel 13 (delegate/loudspeakers) only will be equalized. See
Chapter 13.8 Available Audio Down Link Channels.
To Equalize the system proceed as follows:
11.5.2 Loudspeakers
NOTE: Before carrying out the equalization process, it is recommended that the surround-
ing area be kept as quiet as possible.
The three rotary loudspeaker controls located on the front panel of the Central Control Unit are
used for setting the overall system gain/volume of the DCN’s contribution unit loudspeakers.
•
Control
(FIG 11-2 (6) ) sets the overall volume/gain level of the discussion unit loudspeak-
ers in 1.5 dB steps throughout the entire system.
The number of microphones which can be selected for the ‘auto-equalization’ measurement process
can be selected by the user. Proceed as follows:
NOTE: When turned fully anti-clockwise the audio signal to all system units, with the
exception of the interpreter desk is switched off.
1. Press the equalizing recess switch ‘Start’ located on the front of the CCU to enter the micro-

11.6 Additional stand-alone operations (applicable to confer-
ence units only)
11.6.1 Voting modes
The DCN system in stand-alone operation offers an electronic voting procedure to meet the
majority of conference requirements.A voting session is initiated from the chairman unit.The
chairman unit includes 5 softkeys, two of which are used to either start the voting session‘Start’ or to
Stop the voting session ‘Stop’. A ‘Hold’ key enables the chairman to freeze a voting session for as long
as is necessary.A ‘Restart’ key, restarts the session when in the ‘Hold’ mode.
2
NOTE: For details on how to conduct a voting session using the chairman unit, refer to
Chapter 11.7.3: “Operation Chairman’s unit LBB 3547/00”.
The voting mode available with stand-alone systems is the Parliamentary voting procedure.This mode
of operation allows delegates to register a ‘No’, ‘Abstain’ or ‘Yes’.
11.6.2 Intercom Facilities
If a delegate/chairman unit or interpreter desk is provided with an Intercom handset type
LBB 3555/00, its user can participate in a two-way conversation with an assigned central Intercom
Operator. The central operator position is a single assigned* stand-alone delegate unit with handset.
*Assigned using the CCU maintenance menu.

11.7.1 Introduction
Microphone management as its term suggest, refers to the technique of managing and controlling the
different methods by which delegates are able to use their microphone units.
2
In PC-based systems, the control of delegates’ microphone units can be conducted by a central
operator using DCN’s dedicated software. For further information refer to DCN User Software

11.9.4 Microphone locks
11.9 Interpretation
In its programming mode, the desk can be programmed with a microphone‘Override’or microphone
‘Interlock’ function, or given free microphone access ‘None’.The microphone interlocks are only
active when interpreter desks from different booths, try to gain access to the same channel.
The interpreter desk has two functional modes: the operational mode and the programming mode. In
the operational mode the interpreter desk is divided into two main working sections: the listening
section and the speech section.The listening section at the left side of the unit includes headphone
and loudspeaker monitoring facilities for listening to the floor or other translations.The speech section
at the right of the unit includes controls for the outgoing translation channels. In its programming
mode, operational functions can be set before a conference begins.The programming mode under a
menu driven display enables audio channels to be assigned to specific languages, the selection of the
interpreters A and B output translations, as well as providing an override and interlock facility
between and within booths.
2
11.9.5 ‘Override’
If programmed, the ‘Override’ function allows all interpreters assigned to the same output channel, to
switch-on their microphones and access the output channel on a First-In-First-Out basis - thus
switching off already active microphones.This function therefore, assures that only one microphone at
a time is active on a channel.
11.9.1 Incoming channel control (LISTENING)
‘Interlock’
The interlock function permits only one microphone on a channel to be switched on at any time, thus
preventing other interpreters from using the same output channel.The ‘Interlock’ function therefore
operates on a First-In-First-Served basis.
Each interpreter desk includes a Relay select rotary switch for selection of the incoming language, as
well as three incoming channel pre-select keys a, b, and c.The pre-select keys a, b, and c can be
assigned to the interpreters three most familiar or working languages.The incoming language is
displayed on the units alphanumeric LC-display together with a quality indication, providing the
interpreter with an at a glance indication of the quality of the incoming language. For example the
quality indication displays whether the incoming language is direct from the floor speaker (FLOOR) or
whether its a translation of the floor language (+) or whether its a translation of a translation of the
floor language (-). Monitoring the incoming languages is done via the units built-in loudspeaker (floor
only) or by using headphones or headset.Three rotary controls at the lower left of the unit provide
headphone volume, treble and bass adjustment.A rotary switch at the top left of the unit provides a
loudspeaker volume control adjustment.
‘None’
When programmed ‘None’, interpreters assigned to the same channel can switch on their
microphones simultaneously.
NOTE: In PC-based systems the ‘Override’, ‘Interlock’ and ‘None’ facility can be pro-
grammed for within booths or between booths. In stand-alone systems the ‘Override’,
‘Interlock’ and ‘None’ facilities are only active between booths.
11.9.2 Outgoing channel control (SPEAKING)
11.9.6 Relay Interpretation with auto-relay
To distribute the translation, the desk provides two outputs, output A and output B. Output A is a
preset output used for the interpreter’s normal outgoing output, and output B (if selected during
programming) is used for translating from less common languages, or as a second outgoing language
output where different languages are to be distributed from the same desk.
Selection of the A or B outputs is by means of two push-buttons marked A and B. Red LEDs adjacent
to the push-buttons indicate which output has been selected. If output B is selected, the output
language from that desk can be automatically distributed to the other interpreter desk (booths) for
relay interpretation into other languages (if the auto-relay function is enabled in the desk
programming procedure).
In circumstances where the original floor-language is‘well known’ or not‘so well known’, two different
operational procedures can be used. In normal operational mode (FIG 11-9) the original floor
language is well-known to all interpreters, and they listen to the original floor language for
interpretation.The translations are then fed to the language distribution channels. In situations where
interpreters are unfamiliar with the floor language and therefore unable to interpret it, the system
offers an automated relay interpretation facility (auto-relay - see FIG 11-10). An interpreter assigned
to translate the floor language, translates it into another language easily understood by other
interpreters.The floor language on all interpreter desks will be replaced by this transfer interpretation.
This transfer interpretation or “auto-relay” is then used as the base for further translations.
In the example shown in FIG 11-10, Japanese is the floor and the auto-relay facility is enabled on the
Japanese interpreter’s desk.This interpreter selects outgoing channel B and automatically relays an
English interpretation as AUTO-RELAY to all other desks for interpretation and also feeds the English
language distribution channel.The incoming channel AUTO-RELAY indicator shows on all other desks
that auto-relay is active.
11.9.3 Microphone (Micro)
A microphone on/off switch (Micro) controls the status of the units microphone while a Mute push-
button temporarily mutes the microphone for as long as the key remains pressed.An illuminated light
ring and a microphone status indicator (LED bar) indicates microphone on status.

The language quality indication gives the interpreter an at-a-glance quality of the incoming language.
For example, FLOOR above an incoming language indicates that, that language is the original floor
language.A plus sign (+) displayed above an incoming language, indicates that the translation is based
on a direct translation of the original floor language.A minus sign (-) displayed above an incoming
language indicates that the translation is an indirect translation and based on the translation of another
translation derived from the original floor language.

As well as using the A-output as described above, the interpreter can also select a second outgoing
language for distribution on channel B (if programmed), by using the desks ‘B-select’ up/down keys.
Pressing the ‘B-Channel select’ key, activates the Outgoing B-channel, while switching off the
Outgoing A-Channel.Their associated red LEDs act accordingly.
A+B-Output + Auto-relay facility
As well as using the outgoing A and B-channels, an additional facility is available for use where an
exotic language is unfamiliar to the majority of interpreters. In the desk programming mode the
Outgoing B channel of an interpreter desk can be assigned with the auto-relay facility.This facility
automatically replaces the incoming floor channel with the assigned auto-relay language, which is
distributed to other interpreters to base their translations.To output the auto-relay procedure, the
assigned interpreter simply presses the ‘Outgoing B’ key on his desk.

To activate the microphone place the microphone activating key forward, the microphone status LED
bar and light-ring illuminates.To switch the microphone off pull the microphone switch towards you,
the microphone status LED bar extinguishes. If access to the output channel is denied, the system may
be interlocked. In such a case, wait till the relevant engaged LED extinguishes, then release the
microphone activating key (if on) and switch on again.
Engaged LEDs
The A and B outgoing channel engaged LEDs, indicate when the relevant channels are occupied.A
flashing engaged LED, indicates that this desk’s and other interpreter desk(s) microphones are
switched on to the same channel.
The ‘Mute’ key when pressed temporarily switches the microphone off (if on).
Call
A flashing engaged LED (depends on the microphone interlock selected) indicates that the desks
microphone activating key is in the ON position, but the microphone is not activated.A constant
illuminated LED, indicates an attempt to access an occupied channel while the desks microphone
activating key is in the OFF position.All indications disappear as soon as the channel is unoccupied.
The Call push-button when pressed opens the intercom communication channel, between the
interpreters and the intercom operator.
Message distribution
When the central operator distributes a message using the Message Distribution Software Package
LBB 3582, the message is shown on the top-line of the display, using additional screens if the message
is longer than one screen.
NOTE: In the software application module ‘Simultaneous Interpretation’ LBB 3572, the
option ‘Flashing microphone LED bar when engaged’ can be enabled. If enabled, the micro-
phone LED bar above the microphone switch will flash together with the ‘Engaged LEDs
giving improved engaged status visibility.This option remains also active when the
‘Simultaneous Interpretation. software LBB 3572 or the PC is switched OFF. Disabling this
function is only possible via the software module ‘Simultaneous Interpretation LBB 3572.
Intercom operation
In a system, interpreter desks fitted with a handset can be used for intercom communication with the
intercom operator.To use this facility proceed as follows:
Override/Interlock/None
In the desk’s programming mode, the desks can be programmed to provide an ‘Override’, ‘Interlock’
or a ‘None’ function.
1. Lift the handset to open the intercom communication line
2. At the operator position, an LED illuminates indicating an incoming intercom call.
3. If the intercom-line is in use, a ‘busy-tone’ is heard. In this case replace the handset and repeat the
Override.
The override function enables interpreters on the same channel to override each others microphone
on a First-In-First-Served basis.To activate the microphone when overridden, switch the microphone
on/off key to off and switch on once again.
above steps after an appropriate delay.
In PC-based systems running the DCN software package Intercom LBB 3573, participants using a unit
with an installed handset can also participate in private two-way communication.
Interlock
The interlock function if programmed permits only one microphone, on one channel, at a time to be
activated between and in booths.The interlock function therefore prevents other interpreters located
in different booths from using the same Outgoing channel at any one time until the active microphone
has been switched off.
An incoming intercom call is indicated by a text on the top-line of the display.
NOTE: The intercom function can also be performed with the unit’s microphone and the
headphone.
NOTE: Note:To activate the microphone in an interlock situation, wait till the engaged LED
extinguishes, put the microphone on/off key to off and then switch on again.

Introduction
Entering the interpreter desk into its programming mode, enables the desk’s individual and
interpretation system parameters to be programmed manually prior to the start of a conference.
When in the programming mode some of the desks keys are re-defined as programming keys.
The following is an explanation of the redefined keys.

should be noted however that some menus are applicable only to the desk being programmed, while
other menus are applicable to all interpreter desks installed in the system.Therefore the following
menus will be assigned as ‘Desk only’ and ‘System’.When programming the ‘System’ a single desk only
should be assigned for the task.This is necessary because all interpreter desks can program the system
parameters.

headphones/headsets reproducing the floor channel with a high volume, come too close to
an activated microphone.The minimum distance recommended between microphone and
headphones/headsets to avoid the ‘Larsen’ effect, depends on the type of headphones/
headset, the volume setting and if worn or laid down on a desk or table. User should be
instructed to keep sufficient distance or to set the volume level not louder than necessary.
2
12.2.5 Recommended speaking distance
The recommended speaking distance from microphones is 30 cm (1 ft.).
12.1 System
Where appropriate use cable ducts for extension and mains cables. In order to identify such cables
consider using cable tallies.Trunk-lines where appropriate should be divided into manageable
geographic locations - for example- use one trunk-line for committee members or dignitaries seated
on a stage, and reserve, if appropriate one trunk-line for interpreter desks etc.. It is recommended
that the chairman unit and interpreter desks are connected at the beginning of a trunk-line and not at
the end. In public areas where connectors and cables could be trampled on, consider using protective
metal covers according to the existing protection specification.
12.3 Technical rooms
It is recommended that in technical rooms where DCN’s central control equipment is housed the
following conditions should be met:
•
When units are mounted in a 19” rack ,sufficient rack space is required between heat generating
units to allow proper ventilation. Proper precautionary measures should also be taken inside the
rack (e.g. forced ventilation inside racks) to keep the ambient temperature well below the
maximum allowed temperature so as to extend the life-time of the equipment.
Refer to Chapter 13.. ‘Technical data’ for the allowed temperatures.
12.2 Public areas
•
•
•
•
•
Ensure that the area is a dust-free environment.
Ensure adequate air-conditioning.
12.2.1 Lighting
When placing contribution and channel selector units comprising an LC-display, ensure that the
displays are positioned in such away as to avoid direct lighting or sunlight.The recommended viewing
distance (due to the size of characters) is at arms length 1.5 m with a minimum light level of 50 lux,
or even shorter for channel selector units without back-lighting so as to operate the unit while still
having a good viewing angle.
Ensure adequate ventilation.
Ensure adequate lighting. But ensure that the lighting does not impede the central operators.
Do not place objects on top of the units, which could fall into vents or which could cover them
and prevents proper cooling of the units electronics.This could infiltrate into the unit which
could cause trouble such as fire and electric shock.
•
•
Do not expose units to rain or excessive moisture to avoid the risk of shock or permanent dam-
age to the system units.
12.2.2 Public displays (placement/viewing distance)
Do not attempt to remove the top cover of the Central Control Unit,Audio Media Interface
Unit and Extension Power Supply Unit as you will be exposed to a shock hazard.The covers
should only be removed by qualified service personnel.The units are designed for indoor use
only. Please refrain from subjecting the units to vibration, and never place the units near or over
a radiator, heat grill or in direct sunlight.
Place public displays in positions where they can be easily viewed by all participants concerned.Avoid
placement in direct lighting or sunlight.The size and viewing distance for public displays shall be
selected depending on the visibility criteria for each specific system.Aspects such as viewing distance,
character size for hall displays, contrast an brightness under the usual lighting conditions shall be taken
into account.Advise to be given by the equipment suppliers.
•
In PC based systems, be warned that placing a magnet or loudspeaker system in the vicinity of
the PC will corrupt data files stored on the hard or disk or floppy disks.
12.2.3 Public walkways
In public areas ensure that the cables attached to the system units, including extension cables, are run
and laid out in a neat and tidy manner where they do not interfere and hinder public walk ways.
WARNING: Damage to the power cable may cause fire or a potential shock hazard.
12.2.4 Headphones with interpreter systems
Where appropriate place headphones/headsets with the relevant contribution units and interpreter
desks.

12.4 Interpreter booths
12.5 Ventilation
Pressure and speed of work at most international conferences means that interpreters have to take
turn and turn about to keep pace and ensure a steady flow of smooth interpretation.This means that
each interpreter booth has to be large enough to accommodate at least two or maybe three
interpreters.The specification for interpreter booths as laid down by the international organization for
standardization is briefly as follows:
Maintain good ventilation.Ventilation holes are provided on top of the central control units. Place the
units on a hard and level surface and position at least 4-inches from walls to ensure proper ventilation.
12.6 Cleaning
2
Do not use alcohol, ammonia or petroleum based liquids or abrasive cleaners to clean the
equipment. Unplug and clean with a soft cloth slightly dampened with mild soap and water solution.
Allow to dry completely before operating the relevant unit.
•
•
Booths should be constructed at the back or the side of the hall.
Booths should be elevated to provide an overall, unobstructed view of the chairman, the
speakers and any other relevant visual aids.
12.7 Storage
•
•
A window should be installed across the whole length of the booth.
The inner pane should be inclined with its upper edge towards the hall to avoid acoustic reflec-
tions and mirror effects.There should also be a side window so that interpreters can communi-
cate with one another visually.All glass used should satisfy sound insulation requirements.
The dimensions of the booth, where possible should have a minimum size of 2.5 m (8.2 ft.) wide,
2.3 m (7.5 ft.) high and 2.4 m (7.8 ft.) deep for up to 6 languages, and 3.4 m (11.15 ft.) wide for
6 to 12 languages.
Disconnect the mains supply from all mains supplied units, if the units are not to be used for an
extended period of time. Store in a dust free dry area with adequate ventilation. Do not store in
areas affected by direct sunlight or in high or extreme cold conditions. SeeTechnical data Chapter 13..
t is recommended that contribution and interpreter desks are stored in their relevant suitcases.
•
•
•
•
Booths should not have interconnecting doors, but should open onto a carpeted corridor which
is normally used by delegates or members of staff.
Air conditioning should be provided so that concentrates of carbon dioxide never exceeds
0.10%.
Temperature should be controllable between 18 °C (64.5°F) and 22 °C (71.3°F) by means of an
individual regulator in each booth.The relative humidity should be maintained between 45% and
65%.
•
•
The A-weighted sound pressure level generated by the air conditioning system, lighting and
other sound sources should not exceed 35 dB.
A large working surface should be provided for each interpreter.This should be at least 50 cm
(19 in) deep and not be obstructed by equipment.The surface should be covered with a sound
absorbent material.The working surface available to each interpreter (0.4 m2 (4.2ft2) shall have
individual lighting to produce a uniform intensity of at least 300 lux.
Reverberation time inside the booth should not exceed 0.5 seconds for frequencies between
125 and 4000 Hz.
•
•
A rest room should be provided adjacent to the booths.A separate booth should be provided
for the engineer handling the control equipment. It should be similar to the interpreter booth.
