LBB 4100/ 00, LBB 4100/ 10, LBB 4106/ 10, LBB 4129/ 60 BOSCH DCN DISCUSSION Series

World’ s first digital congress interpretation system, upgraded for even higher performance The Bosch DCN Next Generation Interpretation System brings the benefits of innovative digital technology to interpretation
systems. Digital signal processing and transmission via a simple network system greatly improves audio quality
and simplifies operation and installation.

DCN Next Generation Interpretation System provides flexible management of facilities from small gatherings with only a few languages to large assemblies with as many as 32 languages. The system offers versatility, high audio quality with
20 kHz audio bandwidth, and data transmission security while providing complete control over conference proceedings.

# Modular system approach
By simply daisy chaining the modular DCN Next Generation Interpreter and language channel selector units,
any configuration can be put together. The modular structure of the system means any level of conferencing can be
created without difficulty. Systems can be easily expanded by adding components and PC control with software modules.

# Range of equipment
The range of DCN Next Generation Interpretation System products include central control units, simultaneous interpretation and language distribution equipment, application specific
software modules, information provisions, and installation equipment. This can be complemented by
external equipment such as PCs, video screens, booster amplifiers, and loudspeakers, all of which are fully compatible and easily integrated into the DCN Next Generation
Interpretation System.

# Excellent audio quality
The result of this advanced digital technology is excellent audio performance with no loss in signal quality or level during transmission. Each unit receives a consistently
high quality audio signal. This significantly enhances the
intelligibility of speech. DCN Next Generation virtually eliminates the problems usually associated with conventional systems, such as background noise, interference,
distortion, and cross talk.

# Reduced installation costs
Fast, cost-saving installation is an important benefit of DCN Next Generation digital technology. Thin, flexible, twin-coaxial cable and twin-optical fiber carry all the
system’ s digital signals. This eliminates the need for the costly and vulnerable multi-core cables used in conventional
analogue installations. The twin-coaxial cable and twin-optical fiber can easily be run through existing ducting and cable conduits. These can simultaneously carry up to 32 high-quality contribution channels and
32 high-quality distribution channels.

# Simplified wiring
Gone are the days of complex wiring through bulky trunking. The cables used for DCN Next Generation signal
transmission are a sturdy twin-coax cable moulded with a 6-pole connector and a twin-fiber terminated with
easily mounted connectors.
Both cables are used to transport signals to units throughout the system and can be tapped at any desired
point to connect extra equipment, thus providing a branched-tree topology. Future extensions to the system
capacity, such as adding extra units or increasing the number of language channels, will not require alterations
to the existing system cabling. Power is also supplied to all units via two wires in the same cable, a major advantage.
