The System Installation software makes the task easy
with a choice of two assignment methods:
(1) From the hall, by physically pressing delegate microphone
buttons in sequence. This is registered by the PC which in
turn automatically allocates the unit a number.
(2) From the PC, where the operator selects a random micro-
phone and allocates a number. The next assigned number
will follow on sequentially. The software instantly recognis-
es when a new unit is installed by offering a seat number
for the newly installed unit.
A dialogue box displaying the system configuration is
available at any time, with the total number of installed
delegate and chairman units, interpreter desks etc.
Downloading font sets
It is possible to download special font sets that allow
certain DCN contribution units to display characters in
complex European languages, or icon-based scripts
such as Chinese.
Audio channel assignment
The DCN system offers in total 16 audio output chan-
nels, with a default configuration of 15 distribution and
1 communication channel. Twelve distribution channels
can be assigned to combinations of interpretations,
floor language and intercom, with two channels
reserved for line output and one for delegate loud-
speakers as default. If required, these three extra chan-
nels can also be used for interpretations.
All channel assignments are interdependent. The num-
ber of channels assigned to floor and intercom is
dependent on the number required for simultaneous
LBB 3588 and LBB 3562
DCN Automatic Camera Control
The DCN Automatic Camera Control software is
designed to interface DCN congress systems with the
Bosch Allegiant series of video control switchers. It
selects fixed or pre-positioned cameras (such as the
Bosch dome models) to be activated to display the cur-
rent active speaker at a conference. When a chairman or
delegate microphone is activated on the DCN equip-
ment, the camera assigned to that position is activated.
When no microphones are active, an overview camera
is automatically selected. The image can be displayed on

interpretation. In large international conferences using
15 interpretation channels plus one floor channel, a
channel is automatically assigned to interpreter inter-
com use. In such a case the system performs totally as
an interpretation system.
Note: All distribution channels are available via the
Audio Media Interface Unit LBB 3508. The line output
on the central control unit always provides a floor signal
which is the sum of all active microphones.
The task of assigning audio channels is made easy with
the aid of on-screen channel selection, using a display
with three scroll bars that gives an instant overview of
all channel allocations and the effect of altering any of
these allocations.
System Installation is primarily a preparation program.
Once all microphones and delegate units have been
assigned seat numbers and the audio channels config-
ured and tested, there will be no need to use System
Installation for day-to-day monitoring and controlling
of a conference. However, if the physical layout changes
in the conference hall (delegate units are added, for
example) then the data in System Installation must be
updated, and a message immediately appears in the
installation window.
The conference-related information generated is stored
in an installation file. The user can open, create, save,
delete and save these files under a new name.
Note: the maximum number of interpretation channels
when used in a multi-CCU configuration is 11.
