About Schaltgeraete Studios
Who we are
Schaltgeraete Studios GmbH is a studio for music post-production (mixing, mastering, Dolby Atmos) and film post-production (Foley production, sound design, accessible versions) in Werder (Havel), about 40 minutes from Berlin Hauptbahnhof. It was founded by three engineers: Bernhard Range (mastering and mixing, head of music post-production), Anna von Hammerstein (Dolby Atmos mixing, immersive sound design and Foley recording) and Joh Weisgerber (Foley recording and sound design, head of film post-production).
Before founding the company, Joh and Bernhard worked as musicians. Joh, a bassist and producer, has worked with artists including Flo Mega, Femme Schmidt, The Ruffcats and Jazzanova. Bernhard, a drummer and producer, has worked with artists including Alice Merton, Cobrah, Luana Knöll and Charter, as well as with his own artist project HARTBRAND. Anna has a background in musicology: she has researched how people in other cultures hear their surroundings – the role everyday sounds play and the meanings they carry, for example in Lebanon.
Two further team members support the film department with sound editing and develop new workflows for the studio.
Where we work
Our studios are in the former switchgear factory Schaltgerätewerk II, Eisenbahnstraße 73, 14542 Werder (Havel), Germany. The factory used to build industrial switches, which is where our name comes from – we love switches too, the ones that make sound better. Most mastering is booked online; sessions at the studio are welcome by appointment.
The mastering room
We spent more than a year building our mastering room ourselves, finishing it in early 2024: a room-within-a-room with around three tonnes of wood-based insulation, acoustically designed by Guido Apke. ATC 110 main monitors are flush-mounted in the wall. The room reveals what a home studio hides.
