Shure KSM42/SG
Large Dual-Diaphragm Side-address Condenser Vocal Microphone

OUR PART #  KSM42/SG


The KSM42 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 exhibits exceptionally smooth proximity control and ultra-wide dynamic range.

The KSM42 is the premier choice for capturing sophisticated, powerful and intimate vocal performances. KSM42/SG includes ShureLock® shock mount, Popper Stopper™ magnetic pop filter, aluminium carrying case, and velveteen pouch.

Features:

  • Highly consistent cardioid polar pattern creates a broad "sweet spot" and natural off-axis response
  • Dual-diaphragm design with an active front, ultra thin (2.5 micron) 24-karat gold, low mass, 1-inch Mylar® diaphragm
  • Open cage ShureLock® rubber suspension shock mount with low-profile Popper Stopper™ magnetic pop filter produces a natural space between performer and microphone
  • Prethos™ Advanced Preamplifier Technology exhibits extremely low self-noise with superior dynamic range, transient response and ultra-low distortion for transparent recording
  • 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
  • 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
