Vienna, Austria (September 29, 2026)—The sound department of the Theater in der Josefstadt, located in Vienna, has installed an SSL System T digital mixing system that enables engineers to mix performances from multiple venues.
Known locally as Die Josefstadt, the theater first opened in 1788, was rebuilt in 1822 and remains a notable cultural institution, staging both plays and musical productions. Together with its nearby sister venue, the smaller Kammerspiele, it now forms part of a shared production environment built around SSL’s System T platform.

The Kammerspiele was the first of the two theaters to install an SSL System T in 2024. Raimund Hornich, the head of the sound department for both theatres, moved on to the upgrade for Die Josefstadt after the Kammerspiele installation. “I started in the job three years ago and at that time, both places had very old school mixing consoles,” he says. “I had to install a new system with a modern workflow for theatre productions nowadays and SSL provided that.”

During the summer 2025 closed season, installation work began at Die Josefstadt on a similar system utilizing two 32-fader S500 surfaces. The effort was part of a major refit of the theater, which also included an AoIP network, a wideband Sennheiser multichannel wireless microphone system and a d&b audiotechnik PA system.
System T utilizes Open Sound Control (OSC) to provide real time control of audio objects using the System T user interface for a range of external renderers, directly from the System T user interface. “One of the features I value most is the integration with object-based workflows,” comments Hornich. This feature will allow Die Josefstadt’s operators to integrate Soundscape in the future while working within a System T ecosystem.
