Lawo supports Hamburg’s Evangelischer Kirchentag

Lawo technology played a significant role in delivering audio at the 34th annual Church convention in Hamburg, where around 130,000 people attended the closing service.

A total of nine Lawo crystal consoles were deployed for the 34th “Evangelischer Kirchentag” (Protestant church convention) that took place from 1-5 May in Hamburg, which featured more than 2,500 individual events. The closing service attracted around 130,000 faithful, as well as considerable interest from the media. The 400sqm press center, managed by local public broadcaster NDR (North German broadcaster), provided the various ARD stations (Germany’s public broadcasters) with separate cubicles for their editorial staff. In addition to these workplaces, there were two self-op studios with two four-fader crystal consoles, three studios with sound engineers and three eight-fader consoles and one central control room with a 12-fader crytal console. Additionally, there were three crystal base units without control panels, used solely to switch signals. The central audio administration was managed by a Lawo Nova29 router and VisTool touchscreen software. Radio journalists in OB vans had their own monitor boxes, an Axia xNode that could receive eight channels and connect to the Ravenna stream, and a Lawo KS-16 connected via Ethernet to select the required audio signals. The KS-16 controlled a Lawo crystal console in the master control room, which then supplied a selection of eight channels via the Ravenna network. Part of the appeal of using Ravenna was that it is a non-proprietary technology based on Ethernet. Sascha Schwoll, responsible for the outside broadcast at German public broadcaster SWR and part of the ARD-team that planned and implemented the technical setup at the “Kirchentag” explained: “Because of the Layer-3 technology, we were able to use existing network structures. We wouldn’t have gained anything by laboriously installing new cabling – the use of the existing structure meant that we were able to reduce the effort significantly,”
