Arosa - Switzerland 2025

Client: Pronorm BV

End customer: Arosa, Switzerland

Together with Pronorm, Sonalux realized a fixed installation of a projection on a water screen in Arosa, Switzerland.



The installation consists of two locations: a projection location from which the water screen is illuminated, and a control location housing the audio and operation of the water screen. A stable wireless connection was established between both locations for mutual communication, a technical challenge in itself given the site conditions.

The project was executed in two phases. In the first phase, the complete hardware installation was built (Pronorm preparation). In the second phase, Sonalux was responsible for fine-tuning the installation, writing the software, and ensuring stable and synchronous operation of the entire system. After delivery, Sonalux also provided remote troubleshooting during the initial operational period.
