The SM27 from Shure is a large-diaphragm, side-address cardioid condenser microphone for nuanced vocals and instruments. Enjoy natural reproduction of your sound with this mic’s flat, neutral frequency response and low self-noise. This feature-packed mic includes a preamplifier for transparency, switchable low-frequency filter, and a -15dB switchable attenuator for SPL versatility.

Rugged and versatile, the SM27 is designed to deliver outstanding performance both in the studio and live on stage. It boasts three separate mesh layers that reduce wind and breath noise. Its uniform cardioid pattern provides superior off-axis rejection, while the 3-position switchable low-frequency filter minimizes unwanted background noise and counteracts proximity effect for consistent, extended low-end. Its large, yet low-mass Mylar® diaphragm allows the SM27 to achieve a superb transient response, while its 15 dB pad delivers consistent performance across a wide range of high SPL sources.

Also included in the box with the Shure SM27 Large Diaphragm Condenser Microphone is an A32M ShureLock™ Black Swivel Adapter for secure and easy setup and positioning, as well as an A32ZB Zippered Carrying Bag for safe transport from gig to gig and secure storage when your mic is not in use.
