The requirement for the renovation of the ice rink in Olten, Switzerland, was a voice alarm system according to EN 54 that also offers high performance sound. The basis for the hall sound information and one of the success factors in this project was  the EASE simulation with decentralized sound made by TOA.

The actual sound of the ice rink is now realized with 25 HX-5 Variable Compact Array Speakers. Low frequencies are supported by 15 FB-120 subwoofers while the installed VM-3000 system and certified speakers ensure reliable voice evacuation in all areas. The project was realiced by the official Go Wild AG Dealer event-one Veranstaltungstechnik.
