Southeast Christian Church’s The Block features a d&b audioteknik C Series P.A.

Southeast Christian Church’s The Block features a d&b audioteknik C Series P.A.

It should not be news to Mix readers that full-sized line arrays and digital consoles are part-and-parcel of house of worship (HOW) installations. But what may come as a surprise is the fact that these installs are not just reinforcing spoken-word audio. These venues are also becoming multipurpose facilities, where the congregation meets to enjoy live music performances, enjoy recreation opportunities, have a cup of Joe and much more. For system installers, these expanded services add a new dimension to their specs: While spoken word is still of prime importance, the audio gear that is provided must also offer a thumping low end that concertgoers expect. Mix examined a couple of recent installs to see just how high-end these spaces are becoming. [Eds.

Mirroring a trend in the market, this church added a new 1,200-seat room (The Block) that is youth-oriented and multimedia-intensive. Here, teens can climb rock walls, play videogames, surf the Net and experience concerts. For the audio installation, the church turned to Mankin Media Systems (Franklin, Tenn.), a systems integrator. Tackling the concert-friendly space, Southeast Christian Church envisioned a House of Blues-style setup: a three-sided balcony and small stage.

“It’s pretty small; people get packed in,” says Stephen Roberts of MMS. Immediately, this threw up some acoustical red flags for the company, as spoken word was still high up on the needs, but the owners also wanted the venue to be used during the week, when they would bring in bands and host events.

“The technical challenges were steep from the outset as the first MMS Dream Session revealed Southeast’s desire for functionality that would cost more than twice their initial budget,” Roberts says. “Through our 3D [Dream, Design, Deploy] process, we designed a system that is to broadcast standards for audio, video and lighting.”

To start, the team entered the room’s dimensions and data into [Renkus-Heinz’s] EASE to find out which P.A. would be best suited in the space. “We took the room, put it into computer models and said, based on that, here’s some speaker systems that will work,” Roberts recalls. “The client already had previous experiences with a few of those and selected d&b audioteknik [c Series], and they said let’s hear this one to make sure it will work for the space. So we brought them down to Nashville and they listened to it and loved it.” Twelve months later, the system—powered by d&b amps—was installed.

“With the advent of line array technology, a lot of churches are saying, ‘We’re moving to a more contemporary, louder volume. Can we put in a line array?’ Then at The Block, they want to see the technology—speakers right there where everybody sees them. That’s not necessarily a bad thing. It’s meant to be the club feel with big speakers.

“That’s the second half of the equation,” he continues. “Once you choose your speaker, you model in the space where you’re going to hang it, and visually we can look at the space and say these are going to be problem areas just based on experience, but then the model complements that: ‘Okay, you have a reverb time of 3 seconds currently because it’s all concrete brick.’ So we go in and place acoustics in the model to break down that reverb time to something acceptable for speech. We placed lots of acoustic [treatments] on walls, and with this project, we built a five-year plan of technology implementation, and part of that plan was adding acoustics; they didn’t have enough money up front to completely do all the treatment they wanted. But over the next five years, they’ll purchase acoustics for this additional area.”

To outfit the rest of the space, Roberts chose a Digidesign VENUE for front of house. “Audio is crucial to the system, and as such, the client—after demoing and working with different consoles—selected the Digidesign VENUE as the best trade-off between a great-sounding console and easy volunteer operability,” Roberts says. “To fit the budget for the building, we value-engineered the system to work with the Digidesign MixRack to save money while still providing all the functionality the church needed. Backstage at monitor world, there is another Digidesign MixRack for stage monitors and a patchbay to route audio signals to all rooms in the building, as well as stage inputs.”

Roberts says that the audio from the mics to the console stays analog because it is inherently reliable and cost-effective. The A/D conversion happens at the console and stays digital. The drive lines from the console to the amps are AES digital lines. “We believe in retaining high-quality signals while using the flexibility of digital audio, which is why there is only one conversion point,” Roberts says. Rounding out The Block’s feature set are Sennheiser G2 wireless ears, Shure UHF-R wireless systems, a full complement of lighting and video gear, and more.

While many system installs are fully finished before staff training begins, the technical crew at the church was able to use the gear at their old space before moving to the new venue. “This allowed them to not be shell-shocked when trying to learn everything between two Sundays,” Roberts explains. “The Southeast team is very tech-savvy and was able to pick up the basics quickly, while still learning and trying out some of the more advanced features of their equipment with each new event.”

The project also paid off for Mankin Media Systems, as the company won three of last year’s Solomon Awards (Best Tech Consultant and/or Contractor; Best Overall Church Technology Project; and Best Design, Implementation and Operation of an Audio, Video and Lighting System) at the 4th Annual Worship Facilities Conference and Expo.
