Martin Audio Enhances Live Music Emphasis At CLW Church In Germany

by | Mar 30, 2021 | Audio, Case Studies, Production

The steady growth of the live music component in worship services at CLW, a church in Bonn, Germany, necessitated an upgrade of the sancatury sound system that now incorporates loudspeakers and supporting components from Martin Audio.

The Process of Upgrading

Julian Betker, trainee pastor and vicar at the CLW, states, “We’ve been working on a new sound reinforcement solution to meet our many requirements for a while. On the one hand, we wanted to use our existing technology, including mixing consoles, microphones and subwoofers. Our church lives through, and with, live music—which could be heard with our old system outside the church building as well. However, the positioning of the loudspeakers meant that there was always a risk of feedback. The last important point was to stay within budget. We are a donation-financed institution and thus have to pay particular attention to expenditure.”

Several loudspeaker manufacturers were approached to develop a solution. Integration company Klein Beschallungs- und Kirchentechnik of Cologne, together with Audio-Technica, created a concept utilizing the Martin Audio gear. They placed special emphasis on seamless integration with the existing system. Integration company owner Paul Klein notes, “We’ve been working with Audio-Technica’s products for a long time and for the first time we’ve been able to offer Martin Audio loudspeakers. The quality of the CDD series convinced us. Combined with VIA series power amplifiers and the DX0.5 system controller, we were able to create a convincing argument. In addition, we were able to use the ADORN loudspeakers to provide sound in adjoining rooms at a reasonable price, yet still offering high quality.”

System Setup

Since the church building is a rotunda with a gallery, the sound system is divided into sections. The area in front of the stage is the largest area to be covered (with two CDD12 loudspeakers). The upper tier, which uses a glass pane as a parapet, was covered with two CDD10s. The difficulty was to hit the glass surfaces as little as possible, in order to avoid reflections.

“With the CDD series we can cover the audience area very precisely,” Klein says. “Because of the very precise output pattern of the speakers, it was possible to steer the sound away from the glass balustrade of the balcony to minimize these reflections.”

CDD6 loudspeakers were used below the gallery, and A55 loudspeakers from the ADORN series were used inside the rooms. All are driven by VIA5002 and VIA5004 power amplifiers optimized by presets provided by the DX0.5 system controller.

A Satisfactory Conclusion

“With the CLW we’ve been able to implement a very nice sound concept,” continues Klein. “The CDD loudspeakers deliver sufficient level in the hall; at the same time, they are not susceptible to feedback and there is hardly any escape to the outside. The installation was very successful, also thanks to the many helping hands of the CLW.”

Regarding the audio upgrade, Betker concludes: “We are very happy to work with our new sound system. Our live music sounds more vivid than ever—at every seat. We are positively surprised that the integration of our existing technology worked so smoothly. Once again a big compliment to Paul Klein and his team … the cooperation was great.”
