Earthworks DrumMic DM20, User Manual

Some out-board preamps, mixers, consoles or computer audio interfaces
have actual pads that precede the preamplifier input. These types of pads
will provide preamp input overload protection that is needed (see Fig. 1-B).
Such pads will typically provide –10dB or –20dB attenuation. If an exter-
nal XLR type mic pad is needed, Earthworks offers a LevelPad™ which
provides -20dB of attenuation and is simply plugged into the microphone
cable. The DM20’s lower output level, in most cases, should not require
an external pad when close-miking toms or snares.
Earthworks Drum Mics
The Earthworks DrumKit™ High Definition Three-Microphone Systems™
have had great success because they pick up drum sounds with far more
detail and accuracy than conventional microphones. This improved sound
quality is due to Earthworks® advanced proprietary technologies.
Many drummers such as Jeff Campitelli with Joe Satriani, Steve Gadd,
Keith Carlock, Ronnie Vannucci, Anton Fig, Anthony King and many top
FOH engineers touring with major artists are using Earthworks High Defi-
nition Drum Microphones™ for overheads, toms, snare and kick drum
with exceptional results.
The DM20 is a new generation of Earthworks tom and snare micro-
phones. It features a stable gooseneck for easy positioning that will
stay in place even when the drums are played very hard. It also can
handle high acoustic sound levels up to 150dB SPL. The Earthworks
proprietary polar technology provides a stunning amount of rear re-
jection and a frequency response out to 80 degrees off-axis within 3dB
of the on-axis response. This vastly reduces phase cancellations, min-
imizes the pickup of unwanted sounds at the rear of the microphone
and provides significantly more gain before feedback for live sound
applications.

This so-called pad, is not really a pad, it only
changes the gain of the preamp, and may not
prevent overload of the preamp input.
This is an actual microphone preamp pad,
which is an attenuator that will reduce level
prior to the preamp input.
