The Shure® KSM27 is a side-address condenser microphone with a cardioid polar pattern. Designed for studio use but rugged enough for live applications, the KSM27 has an externally biased 1-inch diaphragm, extremely low self-noise, and an extend- ed frequency response specially tailored for vocal tracking and instrument recording.


  • Cardioid polar pattern – the most commonly used pattern for both studio and live applications
  • 1 inch, externally biased, ultra-thin, 2.5 μm, 24 Karat gold-layered, low mass, Mylar® diaphragm provides superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response and no crossover distortion, while minimizing harmonic and intermodulation distortions
  • Premium electronic components and gold-plated internal and external connectors
  • Subsonic filter eliminates rumble from mechanical vibration below 17 Hz
  • Switchable 15 dB pad for handling extremely high sound pressure levels (SPLs)
  • 3-position switchable low-frequency filter helps reduce unwanted background noise or counteract proximity effect
  • Integrated three-stage “pop” protection grille reduces plosives and other breath noise
  • Internal shock mount reduces handling and stand noisepage3image24705248


  • Extended frequency response
  • Low self noise
  • Exceptional low-frequency reproduction
  • High output level
  • High input SPL capability
  • No crossover distortion
  • Extremely uniform polar response
  • Superior common mode rejection and suppression of radio frequency interference


    The KSM27 produces superior results in any application requiring a high quality mi- crophone. Typical applications include:

  • Voice and vocals
  • Close-miking of acoustic instruments such as piano, guitar, violins, drums, and


  • Electric guitar amplifiers
