How many microphones does the gig need?

Fewer than most people assume. The job is not to capture every component of the kit but to give the engineer control over the parts the PA must reinforce, with the fewest open channels you can manage.

The working minimum is three: kick, snare and one overhead. Low frequency is the one thing a small room will not project on its own, the backbeat has to cut through electric guitars, and one overhead delivers cymbals, toms and the shape of the kit with no internal phase problems at all. Four to seven suits a pub or function band, the extras earning their place in this order: floor tom, second overhead, rack toms. Eight or more belongs to theatre pits, festival stages and anything multitracked.

Fewer well placed microphones beat more badly placed ones, because every open channel brings the whole stage with it. A tom microphone hears its tom for seconds a song and the cymbals, guitar cab and wedge for the rest, cutting your headroom before feedback.

Channel plans that get used

Count backwards from the mixer, not forwards from the kit, and count monitor sends too.

Kick drum

Almost every live kick is miked from inside, through the port in the front head: attack, isolation, and a signal that survives being pushed hard in the subs. Outside the head sounds rounder but hears the whole stage. With no port, sit just outside it near the centre and accept the spill.

Where inside the shell

• How far in. Just inside the port, a hand’s width past the front head, is the default. Deeper, towards the batter head, gives more attack and less shell. Level with the port or outside it gives more boom and more spill.
• Where it aims. Straight at the spot the beater hits gives maximum click, a few degrees off-axis softens the mechanical beater sound, and aimed at the centre of the shell it gives body and weight with far less click.

All click and no weight is usually a microphone jammed against the batter head; flapping cardboard is one outside the port hearing more room than drum. Move it before reaching for EQ, and settle the damping first, because a pillow on the batter head kills ring and absorbs low end.

Why a dedicated kick microphone

A kick microphone is not just a big dynamic: its response is shaped so it does most of the EQ for you. Shure publish the BETA 52A as 20 Hz to 10 kHz with a presence boost at 4 kHz, shaped specifically for kick drums and bass instruments, against the SM57 at 40 to 15,000 Hz, which never reaches the octave a kick lives in. The 52A also has a built-in locking stand adapter with integral XLR, so it drops onto a short stand inside the drum.

The other family is the boundary condenser that lies on the damping inside the drum. The Sennheiser e901 is published as half-cardioid, 20 to 20,000 Hz, 48 V phantom, maximum SPL 154 dB, and needs no stand at all.

Snare

Over the rim, two to five centimetres above the head, aimed about a third of the way towards the centre. Nearer the centre gives body, nearer the rim gives crack and ring.

The angle matters most live. Come in across the drum from the side away from the hi-hat, so the capsule looks at the snare and its least sensitive direction looks at the hats. With a supercardioid or hypercardioid the deepest nulls are off to the rear sides rather than straight back. Then have the drummer play hard before you leave it.

Snare bottom and polarity

A microphone under the drum aimed at the wires adds sizzle the top one barely hears, and it needs a polarity flip. When the stick lands, the batter head moves away from the top microphone and towards the bottom one, so their outputs are near-inverted copies: summed as they are, the fundamental largely cancels and the drum goes thin. Invert the bottom channel and they add. It is still rarely worth the channel live, bringing more hi-hat bleed from below and another phase relationship with the overheads.

Toms, and the hi-hat question

Toms use the snare geometry: over the rim, angled in and down so the cymbal above sits as far off-axis as possible. That matters, because a tom is silent for most of a song and the crash above it is not.

Compact clip-mount dynamics exist for this. The Sennheiser e604 is published as a dynamic cardioid, 40 to 18,000 Hz, weighing 60 g; the Shure PGA56 is the same idea at the budget end. One microphone between two adjacent rack toms covers both, and on a five-microphone plan you take the floor tom and leave the rack toms to the overheads. Tom channels need a gate or a hand on the fader, plus a firm high-pass.

A dedicated hi-hat microphone is usually unnecessary live. The hats are already in the snare microphone, both overheads, the tom microphones and the vocal microphones out front, so a bright, high-gain channel added to an already bright signal mostly invites feedback. The real cases are theatre work with a quiet kit, brush playing, a shielded or electronic kit, and multitracking. If you fit one, use a small-diaphragm condenser above the outer edge of the top cymbal, aimed down and away from the snare, clear of the gap where the air blast thumps the diaphragm.

Overheads, ride and ambience

A single mono overhead is the most underrated channel on a small gig: one microphone on a tall boom, centred and high enough to see the whole kit, giving the drummer’s own balance in one fader that cannot be wrong relative to itself.

A spaced pair adds stereo and air, and the rule that makes it work is mechanical: both microphones the same distance from the snare, measured with a cable run from the centre of the snare head to each capsule. Unequal distances mean the snare arrives at one first, so in mono it thins and drifts off centre. A coincident (XY) pair instead puts two capsules together, angled apart by roughly 90 to 135 degrees on a stereo bar, so there is no arrival-time difference to get wrong and it sums to mono cleanly, at the cost of some width.

Overheads too low is the most common drum miking error. At cymbal height the microphone hears individual cymbals rather than a kit, the nearest crash dominates, and the capsule is in the stick path. The fix is height, not angle: tall boom, counterweight, sandbagged base. Overheads also hear the entire stage, so solo them with the band playing first.

A ride microphone is justified when the ride is a feature the overheads are missing, usually because it sits low and far to one side; try moving an overhead first. Ambience microphones are mostly a recording tool, because in a small room they are a feedback source and the PA behind them is louder than the kit. In a big room a front-of-kit microphone can add weight close microphones cannot.

Phase and the 3:1 rule

Whenever two microphones hear one sound at different distances, the copies arrive at different times. Summed, they reinforce at some frequencies and cancel at others: comb filtering. No EQ fixes it, because it is geometry.

The 3:1 rule keeps it manageable: when two microphones cover two different sources, the distance between the microphones should be at least three times the distance from each microphone to its own source. That leaves the neighbouring source roughly 10 dB down in the wrong microphone, quiet enough that the phase interaction stops mattering. It is why a snare microphone two centimetres off the head coexists happily with an overhead a metre and a half up, and why two tom microphones a hand’s width from their heads but only a hand’s width apart never sound right.

Clip-on mounts or stands

On a small stage this is a floor space decision before it is a sound decision, because seven microphones on seven stands around a drum kit is a hazard as well as an impossibility.

A rim clamp is in position in seconds, uses no floor and can live on the kit, and sitting close to the head it hears less of the rest of the kit. The trade-off is that it couples the microphone to the shell, so vibration and stick strikes arrive as a thump down the cable, which is why better clip microphones use a shock-mounted cradle. Thick and die-cast hoops also defeat clamps built for standard triple-flanged hoops.

A short boom positions precisely and decouples the microphone from the drum, which matters most on the snare; overheads have no alternative. The costs are floor area, cabling and a trip hazard, so the usual compromise is clips on the toms and stands for kick, snare and overheads.

Dynamic or condenser, position by position

Dynamics on the drums, condensers on the cymbals. Dynamics are robust, need no power, tolerate enormous SPL, and their limited high-frequency reach is an advantage on a source that already has too much cymbal in it. Condensers resolve the transients that make cymbals sound like cymbals rather than white noise.

Condensers overhead need care on a loud stage: what makes them better on cymbals also makes them hear the guitar cab, the wedges and the PA, and a capsule half a metre from a crash sees very high SPL. The Audio-Technica AT4053B publishes a maximum input level of 145 dB SPL at 1 kHz and 1% THD, rising to 155 dB with its switchable 10 dB pad, plus a switchable 80 Hz roll-off: exactly the switches an overhead channel wants. They also need phantom power, 48 V for both the AT4053B and the e901. Our guide to choosing live microphones goes deeper.

Gates, and why gating badly is worse than not gating

A gate mutes a channel until the signal passes a threshold, so the tom channels stay shut and the cymbal wash drops out of the mix. Done well it tightens a drum mix; done badly it is unmistakable to an audience in a way a slightly washy mix never is. Too high a threshold swallows ghost notes. Too low and the cymbals open the tom gates anyway, with a chattering flutter around the threshold. And the classic: thresholds set while the drummer plays alone at soundcheck volume, then the band starts 6 to 10 dB louder and every gate opens on every snare hit.

1. Set thresholds with the whole band playing at gig volume. Failing that, set them with the drummer, raise them a few dB deliberately, and check during the first song.
2. Use the key or sidechain filter so the gate triggers on the drum’s frequency range, not on cymbal energy in the same channel.
3. Keep hold and release long enough to preserve the decay. If you can hear the gate close, it is too fast.
4. Use range rather than a full close. Attenuating a shut channel by 10 to 20 dB removes the wash without the on-off artefact.
5. Test against the softest ghost note in the set.

If a gate is fighting you, the problem is usually placement or channel count. A channel gained too low also forces the threshold into the noise, so get the preamps right first: see our gain staging guide.

Electronic drums, shields and volume-limited venues

In a room with a noise limiter, or a small hall where the kit fills the space, microphone technique is not the problem. An acoustic kit is often the loudest source on stage and the one thing you cannot turn down. Our guide to noise limiters in UK venues covers what trips them. Four ways out:

• Quieter kit and quieter playing. Lighter sticks or brushes, low-volume cymbals, mesh or muffled heads. Close microphones matter more, because the room contributes less.
• A shield or screen. A transparent panel reduces what reaches the room and the vocal microphones in front of it, but it redirects energy rather than absorbing it and reflects a good deal back at the drummer, who then needs monitoring.
• An electronic kit. The complete answer: line or DI outputs, level entirely under the engineer’s control, no microphones, no gates, no spill. The trade is feel. Hybrids are common: mesh heads and low-volume cymbals, close microphones on the shells, triggers where the acoustic drum is too quiet.

Multitrack recording tap-offs

If the desk records to USB, SD card or a networked interface, the economics of channel count change. A detail channel that is a liability at front of house is free on a recording, because you can mute it live and keep it in the multitrack. That is the honest case for snare bottom, hi-hat and room microphones.

• Tap before the processing. Record direct outs pre-EQ, pre-gate and pre-fader where the desk allows it, because a gated tom track cannot be un-gated later and the default direct-out point is often post-insert.
• Set gain for the recording too. Peaks that look comfortable on a live meter sit closer to the ceiling on a digital recording.

Common mistakes

• A hi-hat microphone nobody needed. The hats are already in the snare microphone, the overheads and every vocal microphone, so the extra channel adds only gain and feedback risk.
• Overheads too low. You hear individual cymbals rather than a kit. It is a height problem, not an angle problem.
• The kick microphone in the wrong part of the shell. Against the batter head is all click; outside the port is boom and spill. Move it in 10 cm steps, not with EQ.
• No polarity check. Snare bottom left un-flipped, and the drum is thinner with both channels up than with one.
• Gate thresholds set at soundcheck volume. Levels set with a solo drummer fail as soon as the band plays louder.

Popular picks from the shop

Matched sets bundle a kick, snare and tom mics with mounts: the Shure DMK57-52 is three SM57s and a BETA 52A, and the Sennheiser e604 three-pack covers snare and toms on clips.

Frequently asked questions

How many microphones do you need for a drum kit live?

Three is a working minimum: kick, snare top and one overhead. Five, adding floor tom and a second overhead, covers most function and club work. Seven gives every drum its own channel. Ten or more suits theatre and multitrack.

What is the best kick drum mic?

The category matters more than the model. Choose a large-diaphragm dynamic shaped for kick drums, such as the BETA 52A at 20 Hz to 10 kHz with a 4 kHz presence boost, or a boundary condenser made to lie inside the drum, such as the e901.

Do I need a hi-hat microphone?

On most live gigs, no. The hi-hat is already in the snare microphone, the overheads and the vocal microphones. Add one for theatre work, brush playing, a shielded or electronic kit, or when multitracking.

Should overhead drum mics be condenser or dynamic?

Small-diaphragm condensers give the cymbal detail and are the normal choice, but they hear the whole stage. On a very loud stage, dynamics overhead are a legitimate alternative: less air, more control. With condensers, check the desk supplies phantom power and use the pad and roll-off.

What is the 3:1 rule?

Keep the distance between two microphones at least three times the distance from each microphone to its own source. That leaves the neighbouring source roughly 10 dB down in the wrong microphone. It limits bleed rather than guaranteeing phase coherence, so check in mono.

Do I have to gate drums live?

No, and gating badly is worse than not gating. Fix placement and channel count first, then gate with the band playing at gig volume, use the key filter, keep the release long enough to preserve the decay and use 10 to 20 dB of attenuation rather than a hard close.
