|32 Bosch Praesideo Power amplifiers were deployed to handle the power requirements of loudspeakers
To ensure clear and reliable passenger communication at all times and all over its large area, the International Terminal of the Adnan Menderes Airport, Turkey, relies on technology from Bosch. Since its installation by the Bosch partner Ateksis, the Praesideo fully digital public address and voice evacuation system allows the broadcast of different live and pre-recorded messages in 100 different zones throughout the building. Praesideo always adjusts the volume according to the noise level in the terminal so as to guarantee the highest possible sound quality and speech intelligibility. The system also allows the full integration of third-party services, as well as interconnecting with the fire alarm system.
“Praesideo’s technical capabilities were of course decisive – however, its design also played a role when choosing the product”, explains Feray Top, Product Marketing Manager Public Address and Conference Systems at Bosch Security Systems. “Since the International Terminal features outstanding, award-winning architecture, products were required that wouldn’t affect the aesthetic appearance of the building”. Praesideo itself has scooped up several prizes for its design – including the prestigious iF award.
After measuring noise levels in all areas of the terminal, Ateksis installed 187 horn loudspeakers, four LP1-UC20E sound projectors and 15 LBC3200/00 and LBC3200/10 line array loudspeakers. 32 Praesideo Power amplifiers are in use to handle the power requirements of the loudspeakers, while 30 ambient microphones monitor the crowded areas of the building. A total of 18 call stations were positioned at the information desks and emergency exits. The very heart of the system, the network controller, is combined with the fire alarm system and programmed to cope with all the various scenarios encountered in the terminal. Moreover, thanks to Praesideo’s open interface, the Flight Information System and the Central Database System were readily integrated in the public address system.
With more than 7,000 systems installed worldwide, Praesideo is the number-one solution for demanding public address and emergency sound applications. It features 28 dynamically-assigned digital audio channels, digital event scheduling, as well as message management, and it can route background music to a practically unlimited number of zones. Naturally, this comprehensive system is certified compliant with all major standards for emergency evacuation.
