Optimal Placement
Place microphone approximately 1-2" from and at
a 90° degree angle to the speaker cone.
To reduce boominess, move the microphone off
axis to the cone from 90° to 45°, or move mic
from center of cone to either edge.
On double headed Toms place mic over the top of
drum 1-3" and at a 45° angle to the drum surface
and 1-2" in from the drum edge. On single headed
Toms use above method or place mic inside Tom
from underneath at a 90° angle from the center of
head, 3-5", away.
Place mic 1-3" above the heads, 1-2" in from the
rim. Aim each mic at the top heads angled down
about 45°. If the drum rings, tape deadening
material to the head or use damping rings.
For more “snare” sound place a 2nd mic
underneath aimed up at the bottom of head.
Place microphone one to two feet above the
top of cymbals.
Place 5 inches above outside edge at a
45° down angle.
6-24" away, and on axis with the bell of
the instrument.
Place mic 6-12" from where finger board
joins the body.

2.The microphone should be located close to the sound
source to minimize interference from other potential
sound sources.
3. Use the 3-to-1 rule when using multiple microphones.
Place each microphone three times farther from other
microphones as from the desired sound source.
4. Minimize over-handling of the microphone to reduce
unwanted mechanical noise.
5.Working close to the microphone will increase the bass
tone and also provide increased gain-before-feedback.
