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
•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
