  • Highly consistent cardioid polar pattern creates a broad “sweet spot” and natural off-axis response.
  • Passive back diaphragm delivers exceptional control of low frequency proximity effect.
  • Tailored low-frequency roll-off minimizes low frequency room noise.
  • Integrated three-stage mesh grille guards against wind and breath noise.
  • Extremely low self noise for critical studio vocal recording.
  • Premium electronic components and gold-plated internal and external connectors.
  • Internal shock mount to reduce unwanted handling and stand noise.

The Shure KSM42 is a Dual-diaphragm cardioid microphone delivers exceptionally smooth proximity control and ultra-wide dynamic range. It features a natural off-axis response, a dual-diaphragm with a gold Mylar diaphragm, 3-stage grille, and internal shock mount.

Why Are There No Switchable Settings (Pad, Low-Cut Filter) On the KSM42?

The design intent of the KSM42 was to craft a large-diaphragm side-address microphone for the primary application of human voice in controlled environments. Much forethought went into crafting the dual-diaphragm capsule to guarantee superior proximity control and a generous and broad “sweet spot”, with extremely consistent sound quality below 1000Hz. With a max SPL of 139 dB and a gradual low-end frequency roll-off built in, pad and filter settings become redundant.
