L-Acoustics audio was installed during a recent renovation of the CCH convention centre, in Hamburg, Germany. Built in 1973, the CCH is a cornerstone of the European convention scene, and wanted to expand its capacity to 12,000 people, while improving the audio.
The installation of the L-Acoustics system was executed by Protones, a full-service provider based in Lüneburg, Germany. Benjamin Schulenkorf, technical managing director at Protones led the project, along with consultants GRANER + PARTNER.
The team selected the L-Acoustics L Series after testing, primarily for its speech intelligibility, a crucial factor for the diverse range of events hosted at the CCH. The L Series system was designed using L-Acoustics Soundvision in collaboration between GRANER + PARTNER, Protones, and audio consultant Rûdiger Aue.
The main hall features a left/centre/right configuration, with one L2 and L2D speaker forming the left and right arrays, complemented by a centre cluster of one A10i Focus over two A10i Wide speakers.
Four KS21 subwoofers per side, in cardioid configuration, are ground-stacked on either side of the stage, while two X8 are mounted either side of the stage for out-fill and eight 5XT are placed across the stage lip for in-fill.
Two additional hangs of one A10i Focus over one A10i Wide provide stage monitoring. The whole system is powered by L-Acoustics LA7.16i amplified controllers.
The L-Acoustics installation is integrated into a sophisticated media technology network that spans the entire CCH. This network includes Q-SYS Core processors in various halls and utilises Dante audio-over-IP protocol.
The CCH’s commitment to sustainability was a key factor in choosing L-Acoustics as a partner. The venue recently achieved Gold Certification from the German Sustainable Building Council, becoming the first German convention centre to do so.
Gralf Krüger, head of sound at CCH explained: “From the outset, we were looking for a partner that shared our values and would be able to meet our sustainability standards. L-Acoustics was a perfect match.”
Schenke noted: “Although the system is discreet in size, the output is amazing. It means we can meet the requirements of any client without a problem. This renovation ensures we will continue to do just that for many more to come.”
