System Overview
System Overview
Integrus is a system for wireless distribution of audio signals via infrared radiation. It can be
used in a simultaneous interpretation system for international conferences where multiple
languages are used. To enable all participants to understand the discussion, interpreters
simultaneously translate the speaker's language as required. These interpretations are
distributed throughout the conference venue, and delegates select the language of their
choice and listen to it through headphones. The Integrus system can also be used for music
distribution (mono as well as stereo).
Figure 3.1: Integrus system overview (with DCN-system as input)
The Integrus Language Distribution System comprises one or more of the following:
Infrared transmitter
The transmitter is the core of the Integrus system. Four types are available:
– INT‑TX04 with inputs for 4 audio channels
– INT‑TX08 with inputs for 8 audio channels
– INT‑TX16 with inputs for 16 audio channels
– INT‑TX32 with inputs for 32 audio channels
The transmitter can be directly connected to the DCN Next Generation conference system
(see section Connection, page 42).

Integrus Transmitters
The transmitter is the central element of the Integrus system. It accepts asymmetrical audio
sources from a maximum of 32 external channels (dependent on the transmitter type) and can
be used with the DCN Next Generation conference system. It can also be used with analogue
discussion and interpretation systems (e.g. CCS 900 with up to 12 interpreter desks), or as a
stand-alone system distributing external audio sources.

used to connect auxiliary symmetrical audio signals such as a music installation, the
original floor language or emergency messages.
4Audio signal inputs - 4, 8, 16 or 32 cinch plugs to connect external asymmetrical audio
input signals. The number of connectors depends on the transmitter type.
5Earth connection point - Only used for factory testing purposes.
6Radiator signal loop-through input - A HF BNC connector to loop-through the radiator
output of another transmitter.
7Radiator signal outputs - Six HF BNC connectors, used to connect the radiators. Up to
30 radiators can be loop-through connected to each output.
8Optical network connections - Two connections used to connect directly to the DCN
Next Generation conference system with an optical network cable.

Integrus Radiators
The radiators accept the carrier signals generated by the transmitter and emit infrared
radiation carrying up to 32 audio distribution channels. They are connected to one or more of
the six HF BNC outputs of the IR transmitter. A maximum of 30 radiators can be connected to
each of these outputs by means of loop-through connections.
The LBB 4511/00 has an infrared output of 21 Wpp, while the LBB 4512/00 has an infrared
output of 42 Wpp. Both have an automatic mains power voltage selection and are switched on
automatically when the transmitter is switched on.
The attenuation of the signal by the cable is equalized automatically by the radiator. When the
radiator is supplied with power and the transmitter is switched on, the radiator initializes the
equalization. The red LED flash for a brief period of time to indicate that the initialization is in
progress.
When not receiving carrier waves, the radiators switch to standby mode. There is also a
temperature protection mode which automatically switches the radiators from full to half
power or from half power to standby if the temperature of the IREDs becomes too high.

IR radiation
The Integrus system is based on transmission by modulated infrared radiation. Infrared
radiation forms part of the electromagnetic spectrum, which is composed of visible light, radio
waves and other types of radiation. It has a wavelength just above that of visible light. Like
visible light, it is reflected from hard surfaces, yet passes through translucent materials such
as glass. The infrared radiation spectrum in relation to other relevant spectra is shown in the
next figure.
