Integrus - high quality, wireless language distribution

In developing Integrus, Bosch asked a wide range cross-section of congress specialists, 'What improvements would you like to see in language distribution systems?'. The overwhelming response was, no interference from lighting and better sound quality.

Integrus was specially developed to meet these requirements. It is the world's first fully digital infra-red language distribution system. It provides congress integrators and users .

  • No interference from lighting
  • Superior digital audio quality
  • User-friendly selection of 32 channels
  • Easy interfacing with DCN & other congress systems
  • Can be used in bright sunlight

The transmitter is the core of the INTEGRUS system. It accepts analogue or digital input (from DCN), modulates these signals onto carrier waves and transmits these carrier waves to radiators located in the room. Four types are available:

- LBB 4502/04 with inputs for 4 audio channels
- LBB 4502/08 with inputs for 8 audio channels
- LBB 4502/16 with inputs for 16 audio channels
- LBB 4502/32 with inputs for 32 audio channels


One of two different interface modules can be mounted in the INTEGRUS transmitter housing to connect the transmitter to a wide range of conference systems.

LBB 3422/10
Analogue interface for CCS 400, CCS 800 and other analogue conference systems. Up to 12 interpreter desks (LBB 3222/04) for 6 languages can be directly connected to the module in a daisy chain configuration. The module can also accept inputs from other audio sources such as public address systems.

LBB 3423/00
Digital interface for connection of Philips / Bosch DCN interpretation system. The DCN module allows for simultaneous interpretations generated by the Philips / Bosch DCN system to be distributed by the infra-red language distribution system


.INTEGRUS Radiators are used to distribute infrared signals throughout the conference venue, enabling delegates to listen to the proceedings by means of personal receivers. Two types of radiators are available:

LBB 4511/00
medium-power radiator for small to mediumconference venues

LBB 4512/00
high-power radiator for medium to large conference venues

Both types can be switched between full and half power use. They can be mounted on walls, ceilings or floor stands.

For positioning of the radiators and to calculate the number of radiators required, see pdf datasheet or contact Nte.


INTEGRUS pocket receivers are ergonomically designed to incorporate the latest electronics technology, including a specially designed IC, to ensure maximum performance and a long battery lifetime. INTEGRUS receivers can be used for both language and music distribution.

Two multi-channel infrared receivers are available:

LBB 4540/04 for 4 audio channels
LBB 4540/32 for 32 audio channels

INTEGRUS receivers can operate with a rechargeable NiMH battery pack or with disposable batteries. Charging circuitry is incorporated in the receiver.
