the Co4’s versatility will make it a “must have” in any
microphone mix.
Microphone Use and Placement
Please note that miking techniques are a matter of personal
preference.These are merely guidelines to assist in the
placement of the microphone to gain optimal performance.
Usage Optimal Placement
Electric Guitar Place microphone approximately 1-2" from and at
and Bass a 90°degree angle to the speaker cone.
Guitar Amplifier 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.
Tom-Toms 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.
Snare Drum 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.
Cymbals Place microphone one to two feet above the
top of cymbals.
High-Hat Place 5 inches above outside edge at a
45°down angle.

Instrument Microphone

Cobalt™Co4
Instrument Microphone Standard Placement & Use Guidelines
1. Always point the microphone at the desired source of
sound, and away from any unwanted sources.
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.
