Audio information systems are used in places that gather a large number of people and there is a need to communicate important messages. It can be for public use, industrial objects – shopping centres, factories, squares and more. Messages can be pre-recorded or broadcasted directly over the microphone. Their nature can be varied – danger or disaster warnings, evacuation instructions, advertising and information messages. The main purpose of fire alarm and evacuation management systems is to promptly alert people of the dangers they face and to manage the flow of people – to provide information on how to avoid the threat.
The use of audio information systems is also useful when it comes to creating a pleasant environment in the object – transmitting background music. Shopping and entertainment centres have recently become leisure venues. We try to make the visitor feel comfortable, safe and wanting to return to the place they visit, so the installation of modern audio systems in these objects is just a must.

Sound information systems are also very relevant for hotels and business centres. The selection of acoustic systems in these objects is carried out in strict compliance with normative documents and the interior solutions of the building.
Multi-zone sound systems are commonly used in larger objects or complex of buildings. Different messages or music are broadcast in different zones as needed, using separate audio sources. System elements and audio broadcasting can be controlled from different zones or remotely via computer networks.

You may not have known, but you may encounter the audio information system even in ... the church. It is often a difficult task to make the church sound, because the inner space of the church is very complicated from an acoustic point of view, so it requires very careful and responsible work to design and prepare the audio system for end use. Using a sound processors, such system becomes fully automated - without the need for human intervention in determining sound levels, frequency characteristics, and many other parameters for high quality sound reproduction.

The equipment used in audio systems must ensure uninterrupted operation of the system, monitoring of the state of the equipment, control of the audio and microphone lines, backup power of the system components, their automatic replacement in case of failure and other. These requirements are defined in European and Lithuanian standards such as EN54.
Public messaging and voice evacuation systems used in sports arenas are particularly important as they are directly related to human safety and distribution of information during events. Systems also perform sound reproduction in the main sports arena during events. Sound systems are complemented by large-format LED displays, information cubes, and lighting systems.

If buildings or premises are located a few hundred meters or even a few kilometres away and need to have sound, then the best choice is audio systems running on the local computer network (LAN). Such systems require fewer cables, control systems, more convenient and easier maintenance, and lower installation costs than conventional systems. It can be said that the future belongs to messaging systems running on computer networks. Computer-based messaging systems are the ideal solution for hospitals, airports, hotels, exhibition and conference centres, stadiums and sports arenas, shopping centres.
The most sophisticated systems can be implemented without loss of quality, inevitably resulting from using analogue systems, a digital audio signal processed by audio processors, standard 5 or 6 category cables, optical data networks and the Internet.
