The SR20 is a cardioid condenser microphone with clean, natural on-axis pick up and smooth uncolored off-axis rejection, making it a superb choice for a wide range of applications, including reinforcement and recording of vocals, guitar, drums, piano, horns, strings and woodwinds. Its open, easy-to-use pickup is musician friendly.




  • Will accurately capture a voice with the same precision and quality up to 90 degrees off-axis, providing the same pristine sound quality at the front and side of the microphone
  • Up close the SR20 is warm, not boomy, while its unique windscreen assembly eliminates the popping of P’s
  • 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
