Bosch Integrus infrared language distribution system
Integrus is a system for wireless distribution of audio signals
via infra-red radiation. It can be used in a simultaneous
interpretation system for international conferences where
multiple languages are used.
The interpretations created are then distributed throughout
the conference venue, so delegates can select their language
of choice and listen to it through headphones.
If you require assistance please do not hesitate to contact

The most effective method of distributing the interpretations
is by using a Bosch Integrus infrared language distribution
system. Infrared means wireless, so delegates have total
freedom of movement. It means information integrity, because
distributed signals cannot pass beyond the conference
hall. And now, with the Bosch Integrus system, it means
better than ever audio quality, with no interference from
hall lighting, see
In simple terms, an infrared distribution system consists
of a transmitter, one or more radiators and a number of receivers.
Various accessories are also available, such as headphones
cables and battery charges - for a more detailed explanation
of Integrus hardware browse each of the pages in this section
of our site (see index down the side of this page).
Quick overview of Bosch Integrus
is the central element of the Integrus system. It accepts
inputs from either analog or digital sources, modulates these
signals on to carrier waves, and then transmits the waves
to infrared radiators
located elsewhere in the room. The transmitter accommodates
special interface modules to ensure compatibility with these
external signal sources. Depending on the transmitter model,
up to 32 separate channels can be transmitted simultaneously.
The output of the infrared radiators is intensity-modulated
infrared radiation. Each delegate is supplied with a pocket
which has a lens to collect the infrared signal and direct
it to the sensor. These signals are then decoded back into
interpretation languages, which are chosen by delegates using
a channel selector and passed to the delegate's headphones.

Number of channels
The Integrus gives the user real flexibility in choosing the
number of required channels. By using a much higher frequency
band (2 to 8 MHz) it offers four quality modes:
- Standard quality mono (for interpretations). Four
channels of this quality
..can be incorporated into a
single carrier signal.
- Standard quality stereo (for reproduction of music
or presentations). Two
..channels of this quality can
be incorporated in a single carrier signal.
- Premium-quality mono (with double the bandwidth).
Two channels of this
..quality can be incorporated
in a single carrier signal.
- Premium quality stereo (for excellent reproduction
of music or
..presentations). One channel
of this quality can be incorporated in a
..single carrier signal.
The Integrus can therefore provide a maximum of 32 standard
quality audio channels (which means up to 31 different interpretations
+ the floor), more than enough to accommodate even the largest
international conferences. It can also be configured for high
quality stereo sound, with up to eight different channels
available for applications like multimedia presentations or
music distribution. Combinations of standard and premium quality
configuration are also possible.
User-friendly channel selection
The Integrus receivers offer the user the exact amount of
channels available. This eliminates having to scroll through
the unused channels before reaching the required signal. All
receivers in the system automatically update themselves if
the number of available channels changes.
Installation and Maintenance
of the system
The Integrus system is easy to install (installation time
is largely determined by the time required to position and
align the radiators), connection of the transmitters is straightforward
and quick. The transmitter has slots for modules that enable
interfacing with digital or analogue conference systems. All
information regarding installation, configuration and system
status is given on the transmitter front-panel display. The
display also shows the menu, which allows all system parameters
to be set or altered. One easy to use button is all that is
required to select all menu options.
Circuitry in the transmitter and matching circuitry in the
radiators allows effective monitoring of the infrared radiator
function. The status of the radiators is indicated on the
transmitter display and by LEDs on each radiator. The system
is also easy to maintain, maintenance of the receivers generally
involves recharging or replacing the batteries they use.
Once installed, the system can be easily extended to accommodate
more conference delegates, simply by adding the required number
of extra receivers. The basic system structure will remain
The Integrus receivers have an ingenious feature, which allows
installers to test the coverage of infrared radiators without
the need for measuring equipment. Simply by walking throughout
the venue holding a receiver in measuring mode, it is possible
to check the coverage at every point. This makes it easy to
see whether extra radiators are required or if the positioning
of existing ones should be altered. NTE may be able to provide
a site survey of your proposed installation, please just contact
us for assistance.
Integrated Charging Electronics
A breakthrough in technology has made receiver charging more
reliable than ever. The process is regulated from the Integrus
system IC, although each receiver now has integrated electronics
to allow it to manage its own charging process. This ensures
optimum charging performance and maximum battery lifetime.
For distributing interpretations to multiple rooms, the Integrus
transmitter has a master / slave operation mode. This means
that separate (slave) transmitters can be located in the other
rooms, providing exactly the same functionality as the master
transmitter and proving local outputs for radiators. This
removes the need to connect the radiators. This removes the
need to connect the radiators required for the additional
rooms to one transmitter, which cuts the amount of wiring
required and eliminates the risk of capacity overload.
Emergency or auxiliary input
To provide delegates with an additional degree of safety and
security, the infrared transmitter unit includes an additional
auxiliary input, which overrides all active audio channels.
This auxiliary input allows the immediate distribution of
emergency messages to all active channels. The auxiliary input
may also be used for the distribution of music or other information.
Complete integration with
Bosch DCN conference systems
Integrus integrates seamlessly with the DCN Next Generation
