VIPARIS, manager of several convention and event centers in Ile de France, wanted to completely renovate the sound of hall 1 of the Parc des Expositions at the Porte de Versailles. This sound system is used for both security sound reinforcement, but also for commercial use.,

The challenge of the project was to design a sound system to meet the pressure, frequency response, and intelligibility requirements to meet the standards of both security sound reinforcement and commercial use.
