Vienna, Austria/Rastatt, Germany (June 16, 2015)—All of the annual Eurovision Song contest’s audio signals were routed via a RAVENNA/AES67-based IP infrastructure for the first time at a Eurovision event this year.
Both the Lawo Nova 73 audio matrix, including all connected DALLIS I/O systems used by ORF’s broadcast supplier, VideoHouse, and the video and audio distribution of the Lawo commentary solution were based on IP networking technology.
The central audio infrastructure was based on a Lawo Nova 73HD audio routing core, which formed the heart of the audio operation. A total of 10 DALLIS I/O systems were connected to the core via RAVENNA Audio-over-IP technology, allowing decentralized collection and distribution of all signals in the venue, including 96 Sennheiser wireless microphones, 32 Sennheiser in-ear systems and a Pro Tools playback system. The Lawo infrastructure also enabled distribution of all of the sync and timecode signals needed for the production. In total, the Lawo Nova infrastructure routed more than 6,600 audio signals to six OB vans, as well as to the FOH and monitor consoles inside the hall.
All OB trucks, including three vehicles from ORF and three from VideoHouse, were equipped with Lawo m266 or mc256 digital mixing consoles.
The Lawo commentary system used by ORF was also based completely on IP networking technology. The 14-member Lawo crew equipped 45 commentator cabins with Lawo LCU commentary units, which were networked via RAVENNA/AES67 with the Commentary Control Room and the Commentary Equipment Room.
The project was managed by Lawo as a turnkey solution, including developing the technical concept, implementation, on-site support and equipment from Lawo’s rental partner, Audio Broadcast Services (ABS). In total, ABS delivered 15 tons of Lawo equipment to Vienna.
