Service and Maintenance

Our Service Portfolio for Theatres, Opera Houses, Public Buildings, Event Venues, …

We have been equipping event venues with audio, video and media technology for over 53 years. Apart from all-new constructions and complete refurbishments, maintaining and repairing your existing equipment is vital for smooth workflows, increasing the value as well as the service life of your installation, and going easy on your budget. You decide whether we perform comprehensive or sample checks of your setup and what exactly you would like us to check and measure—from the entire system all the way down to a specific controller.
Our in-house service and commissioning team is available for contract-based or occasional maintenance and repair activities. Contact us for on-site activities, remote maintenance coupled with telephone support and even 24/7 service solutions.
