LBB 3513/00
Analog Audio Input/Output Module
• Enables remote interpretation via video conferencing or tele-
phone link
• Interfaces DCN with external analogue audio/music and/or
other DCN systems
• Can distribute DCN channels for external monitoring or
recording
• Connection via standard DCN cabling
The LBB 3513/00 Analog Audio Input/Output module
has two main functions.
It allows external analogue audio signals to be distrib-
uted via the DCN language channels. It also allows all
DCN distribution channels (except intercom channels)
to be distributed to external systems. This enables, for
example:
• Connecting an interpreter at a remote location via a standard
telephone line, ISDN line or video conferencing link for
remote simultaneous interpretations. Video conferencing
allows the remote interpreter to see real-time images of the
speaker on a TV/monitor.
• Distributing an external mono music source in a DCN inter-
preter channel. Delegates can listen to the music via a wired
or wireless (infra-red) language distribution system.
• Coupling two separate DCN systems, which for example
allows two systems to share one interpretation. Audio from a
DCN system can also be sent to a public address or moni-
toring system.
The LBB 3513/00 is mounted from the rear of a
19" (3HU) Eurorack. Up to eight modules can be
housed in one frame assembly. Each module connects
to the DCN trunk cable, and has one analogue input
and output. A maximum of 30 modules can be con-
nected to a DCN system.

PCB Controls and indicators
• Limiter on/off switch with LED indication for optimising chan-
nel signal level input
• Two rotary switches for selecting input channels (1-15) and
output channels (0-15)
• Module initialisation/de-initialisation switch*
• 2 LEDs indicating that the selected input and output
channels are active
• 'Engaged' LED indicating that the selected input
channel is in use
• Error indication LED
• LED indicating presence of remote control
• LED indicating that the module is not initialised
• Power ON LED
Interconnection
• 25-pole D-type male connector for connecting
remote control panel
• Two 3-pole XLR connectors for input (female) and
output (male) connections
• 6-pole circular female connector for loop-through
connecting other modules/DCN units
• 0.3 m (12.6 in) cable terminated with 6-pole circular
connector for connection to DCN trunk line
*Note: Before the Analog Audio Input/Output Module
can be used in a DCN system, the module must first be
initialised so that it is recognised by the DCN Central
Control Unit. Initialisation is carried out by pressing the
initialisation switch located on the front of the module
PCB. The module can be de-initialised by pressing the
switch again.
