Rastatt, Germany (October 10, 2015)—Lawo audio and video equipment enabled the live broadcast premier of a new opus featuring eight organs in five cities across Europe.

In a special event marking the 300th anniversary of the city of Karlsruhe in Germany, organists in the twinned cities of Halle an der Saale, Germany, Nancy, France, Nottingham, England, and Timisoara, Romania, played live with four organists in Karlsruhe itself. Performing Organum—a contemporary organ work composed by Wolfgang Mitterer especially for the occasion—the event was broadcast live via satellite to the Karlsruhe State Academy of Design (Hochschule für Gestaltung; HfG).

It was apparent that the audio and video signals needed to be acquired at the eight locations and relayed via satellite link to the HfG in order to guarantee a synchronous transmission with a stable delay. The audio and video signals were fed to an SNG van from Cologne-based broadcasting and media service provider Media Broadcast and from partners located at the respective churches, and transferred via satellite link to Karlsruhe. They were received by another Media Broadcast SNG, and fed into the Lawo setup for the sound and image installation—a total of nine SNG vehicles.

At the academy, the live video feeds from the organists playing and the music itself were set to a technically and artistically challenging sound and image installation, with the help of two Lawo V__pro8 video processor units and a Lawo mc236 audio mixing console.

Rastatt-based Audio Broadcast Services (ABS) supplied the Lawo video and audio equipment for the event and worked with Lawo’s Service Department to overcome its technical issues. The IP-based V__pro8 processors were required for de-embedding the satellite streams received from the eight churches, and providing separate audio and video signals, as well as for image processing. Together with the Lawo mc236, the V__pro8 supplied the surround mix of the concert for both the live PA system and for recording.
