Growing with the community since its founding in 1972, Hosanna Lutheran Church is now a cornerstone of religious life in Mankato, Minnesota. With four contemporary services a week, plus one traditional service and plenty of high-SPL youth events, its sanctuary sound and video systems were tapped to provide a huge range of content. Despite having loudspeakers made by a respected manufacturer, intelligibility and low-end extension were poor and a regular source of complaints until recently, when Audio Video Electronics (AVE) renovated the system. AVE installed a pair of Danley Sound Labs SH-60 loudspeakers. To give Hosanna Lutheran Church plenty of bass when needed, AVE also gave the church a beefy Danley DBH-218 subwoofer.
“Before AVE’s renovation, we always had complaints,” said Matt Kotthoff, technical director at Hosanna. “The system was muddy, and a lot of our disciples, especially some of the senior members, had a hard time understanding what was being said depending on where they were sitting. Also the system lacked intelligibility and power.” Stefan Svärd, president of AVE, added: “Not only that, the low-frequency extension was simply missing. This was despite its big name components and the fact that it looked like a good system on paper. It simply didn’t translate to real-world performance.”
Svärd designed an elegantly simple new sound reinforcement system for Hosanna. An exploded mono cluster of two Danley SH-60s leverages Danley’s pattern control to cover all of the seating without energising the rest of the structure. Between them, also on the ceiling, is the Danley DBH-218 subwoofer. Svärd repurposed Lab.gruppen C-series amplifiers for the mains and added a Lab.gruppen FB14000 for the subwoofer. An existing Biamp Nexia and EV-DC1 processor condition the system, albeit less now than with the previous components, as the Danley boxes are naturally flat and transparent. A new Midas Pro 3 mixer gives Kotthoff and his team control of the system for complex services, and a Crestron control system provides simple control of audio, video, lighting, and HVAC via iPad or iPhone. Finally, a new 8000 lumen Digital Projection HD projector gives the congregation crisp imagery.
“Everything sounds crisp, clear, and clean,” said Kotthoff. “Nothing sounds harsh or painful. The intelligibility in the whole worship space is outstanding, everything from feeling the bass guitar rhythm to the clear natural sound of both singing and speaking voices. The system is amazing. It totally enhances Hosanna Lutheran’s strong music ministry in so many ways.”
