  • Page 5: System Description And Planning

    1 System description and planning 1.1 System overview 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. To enable all participants to understand the proceedings, interpreters simultaneously translate the speaker’s language as required.
  • Page 6 | en INTEGRUS | Digital Infra-red Language Distribution System Infra-red receivers Two multi-channel infra-red receivers are available: LBB 4540/04 for 4 audio channels LBB 4540/32 for 32 audio channels They can operate with a rechargeable NiMH battery pack or with disposable batteries. Charging circuitry is incorporated in the receiver.
  • Page 7: System Technology

    IR radiation The Integrus system is based on transmission by modulated infra-red radiation. Infra-red radiation forms part of the electro- magnetic spectrum, which is composed of visible light, radio waves and other types of radiation. It has a wavelength just above that of visible light.
  • Page 8: Quality Modes

    Carriers and channels The Integrus system can transmit up to 8 different carrier signals (depending on the transmitter type). Each carrier can contain up to 4 different audio channels. The maximum number of channels per carrier is dependent on the selected quality modes.
  • Page 9: Aspects Of Infra-Red Distribution Systems

    INTEGRUS | Digital Infra-red Language Distribution System en | 1.3 Aspects of infra-red distribution systems A good infra-red distribution system ensures that all delegates in a conference venue receive the distributed signals without disturbance. This is achieved by using enough radiators, placed at well planned positions, so that the conference venue is covered with uniform IR-radiation of adequate strength.
  • Page 10: Ambient Lighting

    The Integrus system is practically immune for the effect of ambient lighting. Fluorescent lamps (with or without electronic ballast or dimming facility), such as TL lamps or energy saving lamps give no problems with the Integrus system. Also sunlight and artificial lighting with incandescent or halogen lamps up to 1000 lux give no problems with the Integrus system.

  • Page 15: Cabling

    INTEGRUS | Digital Infra-red Language Distribution System en | 1.4.3 Cabling Signal delay differences can occur due to differences in the cable length from the transmitter to each radiator. In order to minimize the risk of black spots, use equal cable length from transmitter to radiator if possible (see Figure 1.23).
  • Page 16: Setting The Radiator Delay Switches

    | en INTEGRUS | Digital Infra-red Language Distribution System 1.5 Setting the radiator delay switches As described in section 1.3.6, differences in the delays of the signals picked up by the receiver from two or more radiators can cause black spots as a result of the multi path effect.

    | en INTEGRUS | Digital Infra-red Language Distribution System 1.5.3 System with more than 4 carriers and a radiator under a balcony Figure 1.29 illustrates a situation in which a radiation signal delay occurs and which can be compensated for. For systems with more than four carriers, add one delay switch position per 10 meter (33 feet) difference in signal path length to the radiators which are closest to the overlapping coverage area.
  • Page 21: Testing The Coverage Area

    INTEGRUS | Digital Infra-red Language Distribution System en | 1.6 Testing the coverage area An extensive reception quality test must be done to make sure that the whole area is covered with IR radiation of adequate strength and that there are no black spots. Such a test can be done in two ways: Testing during installation: Check that all radiators are connected and powered up and that no loose cables are connected to a radiator.
