System Check: Dayton Avenue Baptist Church

I got a call recently to go check out the system at a local church here in Xenia, who don't have any full time tech staff in-house. This is a pretty typical arrangement for most churches, and works fine as long as systems are designed for ease of use and reliability over cutting edge features. There are a number of things they are doing well, and the system was designed and set up pretty well to match the room, so I want to highlight some of those things that are working in their favor. They are also doing some cool things with their resources, in setting up a second large gathering space where the video of the service is shown in real-time and a second audio engineer can do a mix specifically for that room.For starters, the audio system in the main room was put in about 2 years ago, and they wanted me to just be able to evaluate it, give my unbiased opinion, and make sure everything was still working as originally designed and commissioned.

This graph was very surprising to me, and it was clear that the integrator's main goal was flatness in the measurement, and they certainly achieved that. While this isn't something I would recommend or practice when tuning a room, the good news was that it was very consistent throughout the space. This room has a single QSC sideline array hung in the center of the room covering 90% of the seats, and the extreme front edges are covered half E10 front fills. There is a single dual-18 sub under the front edge of the stage. This is one of the big advantages of a mono system for an application like this: even coverage. Stereo systems, like many churches install, suffer from lots of lobing and comb filtering, especially with the common split-sub arrangement that shows up everywhere.
