Adding to EAW Line Arrays Solves Coverage Issues for Alabama Church

The decision to push forward with the additional cabinets added to the EAW KF730 line arrays was because 'it had become unpleasant to the ears.'

DECATUR, Ala. – While churches will often require a solution that involves something completely new, every so often, a needed fix can be achieved with a less than a complete renovation.

Such was the case with the recent audio install and retune work done at Decatur Baptist Church, located in a community about 90 miles north of Birmingham. While the church had previously installed a trio of EAW KF730 line arrays about 12 years ago, concerns regarding coverage in the worship space had arisen and needed to be rectified.

The church, which has a congregation numbering around 800, worked for the first time with systems integrator MediaMerge, located in Chelsea, Alabama, to complete the project over a week between Sundays to avoid any cancellations or delays of services, with the new setup introduced during the first week of December.

With the added line array cabinets that were part of the project, it drastically helped with poor acoustical coverage in the worship space.

“They were able to stay on their normal routine other than adding an extra rehearsal, to do additional training, and to make sure that everything rolled out as smoothly as possible,” noted MediaMerge President Ken McKibben. “It’s always a key in the church world (to avoid any cancellations or delays of services).”

The integrator first connected with the Decatur Baptist staff while “doing some work for another church in town,” McKibben said. “Over the course of six months, a relationship began to develop, and then they reached out to us about (their project).”

As part of the installation and work that week, “We needed to retune and add additional cabinets to our line arrays,” noted Decatur Baptist Media Director Rich Daniels. By adding two EAW cabinets to each of the three existing line arrays, along with adjusting the angling of the speakers, it drastically helped with poor coverage in the worship space, to where “we were able to improve from a 10 dB difference from one location to another, to where it was reduced to a 3 to 4 dB difference.” In addition, after reconfiguring the way the amps were wired, so to best handle the added load of six additional cabinets, a Crown CTs 2000 amplifier was included as part of the install.

Regarding the sound improvements, McKibben noted, “When the engineer did the original modeling, the box selection was great. The issue, though, was that there were not enough boxes in the arrays, to where “it wasn’t balanced, where in some areas it was too loud and other places, some people could not hear.” With the addition of two boxes (per array, the coverage) improved to plus or minus 2 dB, front to back, where the typical target would be plus to minus 3 dB.”
