The KSM42/SG Side-Address Condenser Vocal Microphone from Shure is a condenser microphone that features a dual-diaphragm capsule, a tailored frequency response, and extensive pop filtering at the inside and outside of the capsule's grille.

Its Prethos Advanced Preamplifier technology delivers transparent audio quality, and smooth proximity control over an ultra-wide dynamic range. Its cardioid polar pattern minimises off-axis noise and feedback while maintaining a smooth frequency response.

  • Passive back diaphragm delivers exceptional control of low frequency proximity effect
  • Tailored low-frequency roll-off minimises low frequency room noise
  • Integrated three-stage mesh grille guards against wind and breath noise
  • Open cage ShureLock rubber suspension shock mount with low-profile Popper Stopper magnetic pop filter produces a natural space between performer and microphone
