Shure KSM42 manual Pop Filter, Reduction of Proximity Effect

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.
