The Earthworks cardioid condenser SR20 is a multi-purpose instrument and vocal mic with a flat 20Hz-20kHz frequency response, 139dB SPL handling, excellent off-axis response, and 32dB rear rejection

There are some mics that are destined to become studio-standards, one of which, is the Earthworks SR20 multi-purpose instrument and vocal mic. A cardioid condenser with a ruler-flat 20Hz-20kHz frequency response, zero-distortion 139dB SPL handling, and 32dB rear rejection, the SR20 excels on a wide range of sound sources, including vocals, guitar, drums, piano, horns, strings, and woodwinds—for both recording and live sound reinforcement. Another advantage of the SR20 is its smooth, uncolored off-axis response, which is the key to turning unwanted bleed into desirable ambience when recording multiple instruments in the same room.

Earthworks SR20 Multi-Purpose Instrument & Vocal Microphone in one take:

  • Will accurately capture a voice with the same precision and quality up to 90 degrees off-axis, providing the same clear sound quality at the front and sides of the microphone
  • Up close the SR20 is warm, not boomy, while its unique windscreen assembly eliminates “P-popping”
  • Patented design and uniform polar response provide more gain before feedback than other microphones
  • Unscrewing the windscreen of the SR20 allows it to become an instrument mic for piano, guitar, drums, brass, woodwinds and other instruments
  • Textbook perfect cardioid polar pattern with natural on and off-axis performance
  • Provides excellent results for both live performance and recording applications
  • Extreme accuracy in the time domain for faithful reproduction and no smearing or distortion
  • No smearing of low-level signals

Precision and quality performance

Painstakingly crafted to be a workhorse in the studio or onstage, the SR20 is designed to effortlessly transition from tracking vocals in the studio to miking acoustic guitar onstage, or whatever else you have in mind. Its cardioid polar pattern is impeccably consistent across all frequencies, which makes mic placement easier in multi-miking schemes by virtually eliminating phase issues, while providing more gain before feedback.

Thanks to Earthworks’ expertise in building highly compliant diaphragms with fast reset, the SR20 handles transients with ease, reproducing every detail no matter how subtle or sharp. Capable of handling sound pressure levels of up to 139dB without distortion, the SR20 can handle whatever you throw it up in front of.

Uniform 90 degree off-axis response

With its removable metal mesh windscreen in place, the SR20 becomes a world-class, handheld vocal mic, capable of capturing the subtlest of detail in your voice. And for singers who tend to dance in front of a stand-mounted mic, the SR20 has a uniform off-axis response that provides maximum vocal intelligibility up to 90 degrees off-axis. At the same time, it rejects off-axis noise and feedback from surrounding instruments and stage monitors thanks to 32dB of rear rejection.

Removable windscreen for instrument miking

And much like a simple pair of horn-rimmed classes conceals the identity of Superman, unscrewing the SR20’s windscreen reveals “the mic of steel” underneath, turning it into an instrument microphone that fights for truth and justice on acoustic guitar, brass, woodwinds, drums, guitar amp, and more.
