Earthworks SR40V

A Major Technological Achievement
Earthworks’ advanced microphone technologies have made it possible to create cardioid
type microphones with a 40kHz high frequency
response. This provides microphones with the
exceptional ability to capture minute details previously not possible with conventional cardioid
type microphones. The SR40V also has exceptional impulse response which allows it to capture
fast transients quickly and accurately. Its very
short diaphragm settling time allows you to hear
subtle details that conventional microphones
miss. The SR40V vocal microphone has a body
that is well balanced and easy to hold in addition
to an attractive wire-mesh windscreen. You will
appreciate the additional gain-before-feedback
and this mics ability to reject sounds at the rear of
the microphone. The SR40Vs near-perfect polar
response will provide you with the same pristine
sound quality at both the front and sides of the
microphone (i.e. no audible high frequency loss at
the sides of this microphone). Three singers can
sing on one SR40V and all enjoy the same exceptional sound quality. The SR40V will redefine
vocal microphones.
About High Definition Microphones™
During the last decade it has become commonplace for sound recording and broadcast equipment to accommodate extended frequency responses up to 100kHz. With few exceptions,
even the very best of conventional professional
microphones do not offer frequency responses
above 20kHz. However, making a High Definition
Microphone involves far more than extending the
frequency response. Impulse response, diaphragm
settling time and pristine electronics are also key elements. Earthworks’ founder David Blackmer foresaw the need for higher quality microphones, and
Earthworks has been offering High Definition microphones, with extended frequency response beyond
40kHz, since 1996. The Earthworks family of High
Definition Microphones™ have an extremely clean,
natural on-axis pickup, and smooth, uncolored offaxis response with high front-to-back rejection that
makes them superb for a wide range of applications 

Polar Patterns
David Blackmer also invented a totally new polar
technology that provides microphones with nearperfect polar response. When you look at a polar
pattern of an Earthworks microphone, the mid
frequencies, high frequencies and low frequencies all look very much like a “textbook perfect”
polar pattern. In practice this means the polar response of an Earthworks microphone is extremely
uniform over its operating frequency range; the
frequency response at 90 degrees off-axis is very
close to its on-axis response. Such uniform polar response results in less phase problems on
the sides of the microphone and there are fewer
phase cancellations when using multiple mics
placed close together. This new polar technology also provides greater rejection of unwanted
sounds from the rear of the microphone in addition to more gain-before-feedback in live sound
