40kHz multi-use directional condenser microphone

Where to Buy

You’ll love what the Earthworks SR40 high-definition cardioid mic does for your recordings and live performances. Its 30Hz-40kHz frequency response means you’re capturing a far wider range than most mics can touch. The result? Better depth and a truer sound that includes more high-frequency overtone content. You’ll also appreciate how well the SR40’s true cardioid pickup pattern rejects outside sources, and how it gives you impressive gain before feedback.

  • Extended frequency response to 40kHz
  • Multi-purpose directional microphone
  • More gain before feedback than other microphones
  • Less leakage
  • 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
  • Transparent sound quality
  • Shorter diaphragm settling time to prevent quieter attacks from being blurred by earlier louder attacks
  • 30Hz – 40kHz frequency response, revealing subtleties in the sound that are non-existent from microphones with less high frequency range, and enabling musical performances to exhibit greater depth and realism
  • The exceptional rear rejection performance enables the SR40 to easily isolate instruments in a recording or live performance setting, thus minimizing acoustic bleed
