KSM42 Large Dual-Diaphragm Side-Address Condenser Vocal Microphone

Model# SU-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.

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