KSM Microphones

Premium microphones with refined and sophisticated components that capture the world's most accomplished studio and live performances.

Cardioid Polar Pattern
Picks up the most sound in front of the microphone and some from the sides. Less susceptible to feedback in high volume environments.
Tailored Frequency Response
Smooth, extended response. Tuned to accentuate specific types of instruments, or voices.

This premium side-address, cardioid condenser microphone features a large dual-diaphragm capsule, optimized for world-class vocal recording and performance applications. With a tailored frequency response and extensive internal and external pop filtering, the single-pattern, dual-diaphragm design of the KSM42, featuring Prethos® Advanced Preamplifier Technology exhibits an exceptionally smooth proximity control and ultra-wide dynamic range. The KSM42 is the premier choice for capturing sophisticated, powerful and intimate vocal performances.

A milestone achievement in sound reinforcement, Prethos Advanced Preamplifier Technology employs transparent internal circuitry architectures that enable unprecedented audio quality and performance.

  • Highly consistent cardioid polar pattern creates a broad “sweet spot” and natural off-axis response
  • Prethos® Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent recording
  • Dual-diaphragm design with an active front, ultra thin (2.5 micron) 24-karat gold, low mass, 1-inch Mylar® diaphragm
  • Passive back diaphragm delivers exceptional control of low frequency proximity effect
  • Tailored low-frequency roll-off minimizes 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
  • Extremely low self noise for critical studio vocal recording
  • Premium electronic components and gold-plated internal and external connectors
  • Durable zinc die-cast housing and hardened low carbon steel grille
  • Internal shock mount to reduce unwanted handling and stand noise
