Pop Filter
An integrated three-stage mesh grille guards against wind and breath noise. Use the included pop filter
accessory for additional protection against breath and “plosive” noises. The pop filter magnetically attaches to
the front of the shockmount ring.
Reduction of Proximity Effect
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 “sweet spot” of uniform low-
frequency response, allowing the performer to move closer or further from the microphone with minimal
changes in sound quality.
