Large dual-diaphragm side-address condenser vocal microphone.
The KSM42 is a premium side-address, cardioid condenser microphone featuring 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, which includes Prethos Advanced Preamplifier Technology exhibits an exceptionally smooth proximity control and ultrawide 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.
