The High Acoustic Sound Levels of Close Miked Drums
In close miking drums, one should keep in mind that the acoustic sound
level at the microphone head is extremely high. Microphones used for
close miking drums should be able to handle at least 140dB SPL in
order to prevent audible distortion. The DM20 DrumMic™ handles up
to 150dB SPL. With these high sound pressure levels, the DM20 mi-
crophone output level may be as much as +15dBV which may over-
load some types of microphone preamplifier inputs. If so, Inserting the
Earthworks XLR type LP20 LevelPad™ into the microphone cable will
provide -20dB of attenuation to help prevent any distortion or overload.
For more information, please refer to the “Different Types of Preamp
Input Pads” section on pages 1 and 2 of this manual.
Close Miking Snare Drums with the DM20
The DM20 has been optimized for miking toms and snare. With its fre-
quency response of 50Hz to 20kHz, it will provide a full and fat sound
from your toms and a nice crisp sound from your snare. If you feel that
there is too much low frequency response when miking a snare, use ei-
ther a high-pass filter set somewhere between 60Hz and 100Hz or a low
frequency equalizer (EQ) to attenuate (i.e. cut) a few dB in the area of
60Hz to 100Hz for the desired results.
