With a very reverberant acoutic and old distributed sound system leaving the congregation struggling to make out what was being said, a new sound system at Saint Christopher Catholic Church in Marysville, Michigan, has given the 600-seat sanctuary new purpose.
Founded in 1936, Saint Christopher has occupied its current building north of Detroit and barely a half-mile west of the US/Canads border at the Saint Clair River for more than 30 years. Reverend James F Arwady, pastor of Saint Christopher’s Church since July 1, 2015, asked Rob Wisnieski, owner of A/V, lighting and communications systems integrator RMW Productions, to design a solution.
RMS specialises in systems for schools and churches, so Wisnieski understood well the challenges at Saint Christopher. He recommended a combination of a basic design change in the sanctuary and replacing the old distributed sound system with a single Renkus-Heinz Iconyx Gen5 IC8-RN digitally steerable line array loudspeaker.
‘The altar area was centrally located, and the seating went a 285° around it,’ Wisnieski explains. ‘They lost a lot of seats with that layout. They had a new priest [Father James] who was a mechanical engineer, and he decided to redesign the space. We helped out with that project.’
Rearranging the room improved things but did not alleviate all of the issues: ‘It’s a very oddly shaped building, and they didn’t want a ton of speakers hanging in it,’ Wisnieski describes.
Instead, he installed the Renkus-Heinz Iconyx Gen5 IC8-RN, which houses eight 4-inch loudspeakers, each with a mini-array of three 1-inch tweeters, all controlled by eight channels of DSP and driven by eight channels of audiophile-quality amplification. This gives the IC8-RN the capability of developing up to four independent, steered beams, which Wisnieski thought could cover the whole church if the cabinets were strategically placed.
Wisnieski placed the IC8-RN on the wall behind the pastor, which seemed even more audacious than using a single array for an entire church. ‘People told me that I couldn’t put the loudspeaker up front, behind the person speaking because it would cause feedback,’ he recounts.
But Renkus-Heinz’ precision beam-steering technology allowed Wisnieski’s calculated gamble to pay off. Once properly configured, his solution not only proved highly effective but relatively easy to implement. ‘We didn’t have to do a whole lot,’ he confirms. ‘I created two lobes: a very small lobe just for the front area, where the priest is sitting, and a bigger lobe firing over the priest’s head to the back of the room. The big lobe is programmed to start hitting the floor 25ft out, so we don’t get feedback.’
The simplicity of the sound system made networking unnecessary, so signals from microphones and musical instruments run analog to a small QSC mixer, then analogue again directly to the IC8-RN. A subwoofer is also installed in the loft to provide low end for the organ.
The small lobe delivered big benefits. ‘That small lobe is a good foldback monitor for the priest, as well,’ Wisnieski says. ‘It was nice to hear the priest tell me, ‘I don’t have to speak as loud because I can hear myself. I used to feel exhausted when I got done with the Mass. Now I can talk in a more relaxed voice, and I’m not straining.’’
Wisnieski’s bold design is a true win-win-win for Saint Christopher Church. A single cabinet, while not quite invisible, is hardly intrusive; the priest hears himself well and can speak normally; and, best of all, intelligibility for the congregation is better than ever before. ‘People who had not been able to hear what was being said at services for 20 years came up to us the first Sunday we got the system running and said, “This is the first time I’ve ever been able to hear clearly without turning up my hearing aid”,’ Wisnieski reports.
