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.

Infrared Distribution 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 image.

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 set-up
The transmitter 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 receiver, 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 same.

Testing Coverage
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.

Room Coupling
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 and DCN wireless using an optical network for a maximum 31 different languages, plus floor. Use Integrus with CCS 800 Ultro and the analog 6-channel interpreter desk for perfect reception at smaller meetings. Or easily interface with virtually any other brand of congress system.

Other uses: Music distribution and hearing assistance
The Integrus offers more than just language (interpretation) distribution. Its flexibility and high audio quality also make it suitable for:

- Music distribution. In places as diverse as fitness centres and factories,
..it can provide a choice of music for listeners in locations throughout the ..premises.
- High quality audio distribution. Multi-lingual cinemas can offer different
..language soundtracks in the same hall.
- Hearing assistance. Helps the hard of hearing in places like theatres and
..other public buildings
- Concert halls and live theatres can distribute the amplified sound in high
Quality to the musicians on stage without interference or risk of feedback
- Distributions of instructions. TV studios can use the system to distribute
..instructions from the control gallery to the cameramen without RF
..interference
- Tour guide. Canal boats and museums can offer their customers the tour
..information in their own language with high quality audio
- Provides musicians on stage the audio they require for their performance
- Interpretation schools. Distribution of the floor and the interpretation on
..respectively the left and right channel for simultaneous listening to the floor
..and the selected interpretation.
