Shure A4PF — Magnetic Pop Filter for Shure Shock Mounts
A4PF Overview
The Shure A4PF is a purpose-built pop filter engineered for use with the SM4, KSM32, KSM40C, and KSM44MP microphone shock mounts. Its magnetic attachment system allows for fast, tool-free installation and removal, making it well suited for studio environments where microphone changes are frequent. The contoured design mirrors the curve of the microphone capsule, maintaining a close, consistent proximity without introducing unwanted reflections or airflow disruption. Recording engineers and studio operators who require reliable plosive control with minimal setup friction will find the A4PF a practical addition to their microphone chain.
The low-profile form factor keeps the performer’s view unobstructed, supporting natural delivery during vocal tracking or voiceover sessions.
