Church Sound: Does Your System Need A Tune-Up?

Some simple -- and relatively inexpensive -- steps that can revitalize a system's performance

Wouldn’t it be great once we’ve gotten a new audio system up and running that it never required any attention?

That’s probably the most frequent dream church sound techs have besides that brand-new automated digital console, right?

The fact is that even the best designed and installed sound systems require a tune-up every now and then to perform at their best.

Before you break out the toolbox (or the checkbook), here are some basic troubleshooting steps:

—Identify your symptoms. This might seem more than obvious, but because components are interconnected with wires and powered by electricity, there are a number of places that your system might be failing.

For example, have the Rice Krispies Brothers (Snap, Crackle, and Pop) and their idiot Uncle Hummer decided to take up residence in your system? Do wireless microphones drop reception? Have your high frequencies pulled an Elvis and left the building? Knowing the symptoms is most important, then you can deal with the fixes needed to tune the room up well.

—Assess your timing. How long has the system been misbehaving? Have you made any significant changes in your instrumentation or microphones? Have you added or removed a piece of equipment recently? Do you plan to stay in your current facility for quite a while longer?

In the grand scheme of things, you might only need a temporary fix for now because you’re planning to upgrade equipment or move into a new facility in the near future.
—What is the REAL problem? Sometimes, we jump to conclusions and make the problem bigger than what it actually is. Are your microphone, drive lines, and equipment rack cables terminated and labeled correctly?

Or maybe you have electrical lines and audio lines too close to each other or they might actually be strapped together, which is an almost guaranteed problem waiting to happen. Is one or more of your loudspeakers not functioning?

—Documentation and diagrams. If you don’t have an accurate hook-up diagram of your system, then you can’t really troubleshoot the system well. As previously mentioned, even if your entire system consists of a single powered speaker with an on-board mixer, there can still be an issue with electricity or a cable that has gone bad.

Getting your documentation together is very important for your current system, particularly if you need to add more equipment to get the best performance.

—DSP. Easily one of the most common problem in sound systems is the processing of the loudspeaker system. If you’re still using an analog crossover or graphic equalizer, then your system could be in need of some upgraded processing.

If your loudspeakers are still in good working order, the new DSP can make a huge difference in your system performance.
