Microphones
The Earthworks DrumKit™ High Definition Three-Microphone Systems
have had great success because they pick up drum sounds with far more de-
tail and accuracy than conventional microphones. This improved sound qual-
ity is due to proprietary advanced technologies utilized in Earthworks High
Definition Microphones.
Many drummers such as Jeff Campitelli with Joe Satriani, Keith Carlock
with Steely Dan, and FOH engineers such as Randy Lane with Dream The-
ater, were using Earthworks High Definition Microphones™ for overheads
and kickdrum with exceptional results. They then wanted the same excep-
tional sound quality from their snare and tom mics. With the introduction of
the DP30/C microphone, they were able to get the same pristine, detailed
sound from their toms and snares as they were from their Earthworks High
Definition drum overhead mics.
We worked with major artists for nearly two years developing and field test-
ing our new High Definition tom and snare mics. During the development
phase, we miked a set of drums with nine Earthworks High Definition Mi-
crophones (including our new tom and snare mics) and also nine industry
favored mics. When veteran engineers heard the difference between these
two recordings, they made the comment that the improvement was so dra-
matic, it didn’t even sound like the same set of drums. They all agreed, “the
increase in detail and sound quality was staggering.”
The DP30/C, designed specifically for use with snare drums and toms.
The DP30/C has a flexible mini-gooseneck for easy positioning and can
handle up to 145 dB SPL. The Earthworks patented polar technology pro-
vides excellent rear rejection and a uniformity of frequency response out
to 90 degrees off-axis. This vastly reduces phase cancellation or other
phasing issues, and minimizes cymbal leakage as well as acoustic feed-
back problems in “live sound” applications.

the New Science in Microphones
David Blackmer, the brilliant engineer who invented the unique technolo-
gies of dbx, is also the inventor and founder of Earthworks. In the last few
years of his life, David developed a number of revolutionary technologies
that dramatically improve the quality and performance of microphones.
In short, Earthworks High Definition Microphones™ will pick up sounds

Miking the Hi-Hat
There are many various approaches to miking a high-hat. We suggest that
you use the SR30 and place it approximately two inches above the top high-
hat cymbal (see Fig 11-A). You can also place the microphone under the high-
hat in relatively the same position as shown in Figure 11-B. However, if the
microphone is placed near the area where the two cymbals come together,
the bursts of air from the two cymbals coming together may result in an un-
desirable thumping or popping sound (see Fig 11-C).
