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
