Context
Inaugurated in 1998, Stade de France is a major arena, with a jauge of 80 000 spectators
The arena is intensively used for multple activities (football, rugby, athletism, concerts...), with different tribunes configurations depending on the event.
Consortium Stade de France decided in 2010 to renovate completely the audio system, with following objectives in mind:
- provide excellent audio quality and comfort for all spectators, whatever the stadium configuration
- provide best possible intelligibility (clarity of speech), and conformity to secutity standards
- full control and optimization of audio volumes everywhere in the arena
- permanent audio level measurement in and out the arena, for a better real time adaptation

- All devices are connected through EtherSound, allowing real time monitoring of all connected devices, and action in case of failure
- all equipments parameters can be adressed and changed in real time from control room (supervision software)
