The Porsche Arena in Stuttgart, Germany is home to a multi-purpose indoor stadium that seats 7,500 spectators. Flexibility is the key and this is also mirrored in the diversity of the events. From superstars in the national and international music scene to sports events and big show productions – the programme of events is as star-studded as it is emotional.

TOA was carefully selected to come up with a sound reinforcement system that can deal with the high reverberation times. TOA designers chose the SR-A12 line array series to attain the best speech intelligibility in combination with high sound pressure levels.

Simulation
TOA created a 3D model of the arena and simulated the sound field using the SR-A12 speakers using the sound simulation software Ulysses. This information TOA delivered the optimal loudspeaker direction and rigging points directly to the installation partner Hellwig Tonanlagen GmbH who also produced all the detailed documentation. The purpose was to achieve the minimum of 0.5 STI measurements in an empty acoustic space. TOA exceeded all expectations and was independently tested via an acoustic consultant.

Separation of the Voice Alarm System
In order to fulfil all the national and international standards, TOA decided that an independent voice evacuation system should be applied and the natural choice was the international accepted TOA VX-2000 system. This, with an additional central cluster of horn speakers powered by only 1200 watts, reduced the emergency power supplies making cost savings that could be utilised elsewhere.

The result of the entire performance was greatly appreciated by Porsche, knowing that they have complete flexibility over the entire system to meet their constant changing demands, as and when they want.
