Bosch combines sound and security in Nuremberg
- Details
Thanks to cost-effective solutions planned and implemented by Bosch, the arena is highly secure – while at the same time providing crystal-clear sound for all its events. The building makes the most of IoT, connectivity and digital solutions: In addition to the latest IP technologies for video surveillance, intrusion and fire protection, the arena also hosts an integrated solution for public address and voice alarm, which completely dispenses with analogue transmission paths.
With its quality sound, quick voice alarming, and crystal-clear speech for emergencies, the easy-to-use sound system and voice alarm solution implemented in the Nuremberg arena meets all requirements for major events and sets a new standard for future projects.
The technological heart of the system is the IP-based Praesensa system from Bosch, a flexible solution with a built-in fail-safe due to its innovative multi-channel amplifier architecture. A digital mixing console and radio microphones are connected to the system, and a total of 56 certified full-range loudspeakers from Electro-Voice were installed in the interior of the Kia Metropol Arena.
The acoustics of sports halls are often considered particularly difficult to get right due to the reverberation caused by the spacious architecture. To address this, Bosch’s sound system experts and acoustic designers ran extensive simulations in a 3D model, in combination with fine tuning on site.
The result is that the 20,000-watt system transmits excellent sound, guaranteeing clarity of speech in every single seat; the system covers all buildings and rooms, including VIP lounges, press rooms, catering, changing, and training zones where additional loudspeakers are installed. All announcements can therefore be heard everywhere, with the best possible speech intelligibility.
The fully digital system isn’t only superior in terms of acquisition costs, but also in terms of performance with a high level of cost-effectiveness and operational ease. Announcements can be made live or played automatically from digital memory. Meanwhile, maintenance by Bosch can be carried out quickly and remotely, while adjustments can be made easily by updating the software. At the same time, the solution is highly energy efficient, as the system was designed to keep power consumption as low as possible.
