Shure's KSM42 is a dual-diaphragm cardioid microphone delivers exceptionally smooth proximity control and ultra-wide dynamic range. It features a natural off-axis response, a dual-diaphragm with a gold Mylar diaphragm, 3-stage grille, and internal shock mount.
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.
Shure KSM42 Features
