I’m always asked how to set up drum mics, and how to control the level of what is the loudest instrument on the worship stage. After asking a few qualifying questions to determine the whys and the wherefores, I usually have some suggestions—because the problems are so common that the solutions always seem to be the same.
Drums Are Not Loud. Drummers Are!
Getting great sounds from drums isn’t just about the drums themselves sounding good—although that is crucial—but also about a drummer who knows how to tune, maintain, and play them. For starters, drums will sound better with new heads that are tuned correctly and musically (think intervals, like perfect fourths), and from which any rings and rattles have been reduced or eliminated.
There’s an old saying, “garbage in, garbage out” (GIGO for short) that applies to any instrument or voice. No microphone will ever make something bad sound better—all a really good mic does is to reproduce the bad sound as accurately as possible. Choosing the wrong mic (like one with an omniDefinition:

I still marvel at how churches sometimes spend an inordinate amount of money to fix the wrong problem. For example, because the drums are loud, they think adding a plastic acrylic screen is the answer. But it’s only half of a solution! Surrounding the loudest of all instruments with a highly reflective surface is a recipe for disaster, because the screen reflects most of the sound that hits it—and what you really need is something that absorbs sound. It’s not too much of a stretch to say that the main benefit of an acrylic screen is that it’s a great place to affix material that absorbs sounds, like acoustic panels or foam.
A lot of churches also think electronic drums (like Yamaha's DTX Series, DTX10K-X pictured) are the answer, and they can indeed help keep levels under control (Fig. 1).
As a group, jazz drummers are often worth emulating. In a scenario like a piano/acoustic bass/drums trio, they have to play with finesse and control. Those same traits will help make for not just a better drummer, but a better service.
The Recipe for Great Drum Sounds
Let’s look at the ingredients which, when combined in the right proportion, guarantee a great drum experience.
A good set of drum(s), tuned and free from unwanted noise/ tones. Choose the instruments that match the room—think size and projection, and remember that smaller rooms want smaller drum sets. Smaller drums have less tension on the heads, so they’re not as loud. An alternative is tuning standard drums higher. Although there will be more tension on the heads, they’ll respond well to lighter touches (which, of course, requires a drummer who knows how to dial back the force). An inexpensive mahogany set, with smaller drum sizes, will tend to sound quieter than a maple set with regular-size drums. Portable kits aren’t only easier to lug around and set up, but can potentially be quieter than a full-size kit. Some “cocktail sets” are also quieter than standard drums (and let’s face it... a drummer who stands up looks cool anyway).
Find the location on the platform where the drums sound best. I don’t care where they look the most visually appealing, where do they sound best? Don’t underestimate this step! Move the drums to various places on stage, and take notes on what works best. Also, try isolating the cymbals with an acoustic panel, like the Clearsonic S2466X2 to keep cymbal sounds from spilling over into vocal mics (cymbals are loud enough as is). If you keep having the same problems but don’t change anything...well, you know what they say about the definition of insanity.
A drummer who knows about nuance. You need a drummer who knows how to play to a particular space, plays well with others, and understands the relationship of touch, dynamicsDefinition:
In a musical performance, changes in overall volume levels, often accompanied by timbral changes. Example: Classical symphonic music has a wide dynamic range, while dance mixes have a much narrower dynamic range., and volume. Not all drummers are the same, and you may need to undergo a search to find someone who understands the unique needs involved with playing in Houses of Worship.
A sound operator who knows about microphones and mixing. However, that’s not enough: the person doing the mixing needs to make sure that everything serves the needs of the congregation, as well as the musicians.
Microphones: The Crucial Link
Typically, fewer microphones will almost always sound better than more microphones. If your sound system is monoDefinition:

One of the simplest solutions for drum miking is to buy a drum mic kit, like Shure’s DMK57-52 (Fig. 2). This includes a kick drum mic, and three Shure SM57 mics—about as close as you can come to an industry-standard drum mic.
If you want to get more involved in close miking, then a drum mic kit like the Audix DP5PLUS is a good choice—it includes 2 rackDefinition:

For a high-end drum-miking kit, I’m a huge fan of the Earthworks DK7 (Fig. 3). This is a premium condenser mics collection with 4 cardioid mics designed for close miking toms and snare, 2 cardioid mics for overhead pickupDefinition:

There is so little need to EQ anything with them that they’re almost magical. The gain and the tonal response stay consistent to the edges of the pattern, resulting in a very natural sound—you have to hear them to know what I’m talking about. They’re expensive, but are sometimes available on sale so keep an eye out for any deals. I’ve heard nothing better on drums (or pianos and choirs, for that matter).
If you need more kick, place a microphone with excellent low-frequency responseDefinition:

Two-microphone setup:
It’s surprising how well a simple, two-microphone setup works—a condenser mic for the overhead to pick up the kit, and a dedicatedDefinition:

Spacing two microphones 3 to 10 feet apart to create a stereo image., or X-Y configuration.
Another way to use two microphones is one for the overhead, and one on the snare. When playing live, the kick is often loud enough that it won’t necessarily need a mic.
Three-microphone setup:
Perhaps you need to hear more of the snare. Typically, you’ll place a dynamic mic like the Shure SM57 1"-2" above the snare’s rim. Point it down to get more attack, or aim it toward the center for tone. Keep it out of the drummer’s way. Even moving the mic as little as an inch or two will give different tones and responses, depending on the mic’s type and polar pattern. Always move the mic to fix the tone before trying to do so with equalization. Also, consider using condenser mics on the drums for their faster transient responseDefinition:

Four-microphone setup:
This covers the entire kit 80% of the time. It could be two overheads (small or large-diaphragm condensers) in a spaced-pair (pay attention to horizontal and vertical planes so that the microphones are equidistant from the snare or the center of the drum kit), a coincident (X-Y) arrangement, or a variation on the “Glyn Johns” technique—a 3 or 4-mic drum miking setup used on countless records. You’ll be amazed at the results.
If you want to put a mic on every drum, go ahead, as long as you’ve taken the time to prevent phase anomalies from occurring. Use your EQ to limit the frequencyDefinition:
A value, expressed in Hertz, that indicates how many cycles of a periodic signal occur in one second. ranges of the different drums and cymbals to only those drums (your snare mic doesn’t have a bass response low enough to pick up your kick). Use high-pass (low-cut) EQ on the snare, hi-hat, upper toms and overheads. You can mic toms closely, but try to make sure the mics are out of the way of errant stick hits (Fig. 5).
Try to keep reflections from hard surfaces (sheetrock, plastic, etc.) from entering into the mics. This will definitely smear the sound, and affect your sound negatively.
There’s not enough time or space to go deeper in this article about microphone choices, polar (pickup) patterns, equalization, dynamic processing (compression/gating), monitoring, and all the other ways to make miking sound even better—but if you start here, you will hear a difference.
