Shure - KSM42 Large Dual-Diaphragm Condenser Microphone with Shockmount+Windscreen

The KSM42 is the premier choice for capturing sophisticated, powerful and intimate vocal performances.

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

How Does It Work?
To counter proximity effect, the KSM42 uses two diaphragms, one active and one passive, to create an acoustic phase shift at the rear of the microphone. This produces a broad area of uniform low-frequency response, allowing the performer to move closer or further from the microphone with minimal changes in sound quality. This results in extremely controlled proximity effect, reduced "plosives," and providing a large "sweet spot" for vocalists, while still maintaining a consistent polar pattern throughout its frequency response. With these characteristics, the KSM42 also excels as a voice-over microphone.

Features
• 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
