Once used by the Conclave to elect new Pope of the time Martin V in 1417, the great assembly hall (Konzilsaal), Konstanz, Germany, is today used as a concert and event venue. The recent installation of a new Vivace Acoustic System from Salzbrenner Stagetec Mediagroup ensures the loudspeaker system can compensate for deficiencies in the existing acoustics.
During classical concerts, up to 800 listeners are grouped under a 3.5m- and 4.5m-high ceiling, which is supported by the massive oak beams. In addition, ceiling cavities opening up to the attic pose an additional acoustical challenge.
The hall owners opted for a Vivace acoustic system from Stagetec, which has been designed specifically to increase reverberation time.
The system consists of a Vivace room-enhancement mainframe with its processors, 35 speakers installed around the space, and six room microphones - all contacted via a dedicated Nexus audio network. The microphones pick up the sound of the orchestra, the soloists, and the noise of the auditorium and pass it to the Vivace system located in the machine room. Here the incoming signals are analysed and processed in real time and subsequently passed to the fully redundant Nexus for conversion and routing to the speakers for playback. With a few exceptions the speakers are built discreetly into the attic, thus maintaining the unique appearance of the auditorium.
"It‘s fair to say that with Vivace our customer achieves exactly the natural, plausible sound which is so important for classical music. At the same time Vivace improves sound quality in disadvantaged areas of the room," commented Stagetec's product manager Bjorn van Munster.
