KSM42/SG

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

• Dual-Diaphragm, Front-Active, Externally Biased Condenser
