Shure SM27 Cardioid Multi-Purpose Condenser Microphone

The Shure SM27 is a versatile, high-performance cardioid large diaphragm condenser microphone, perfect for both professional studio recordings and live stage applications. Engineered to deliver precise, transparent audio across a broad range of vocal and instrumental sound sources, the SM27 is an essential tool for musicians, sound engineers, and producers alike. With its rugged build and advanced design, including a switchable low-frequency filter and a -15dB attenuator, the SM27 ensures superior performance and durability under even the most demanding conditions.

Featuring a low-mass large Mylar(R) diaphragm, the SM27 provides superb transient response and a flat, neutral frequency response for natural sound capture. Its uniform cardioid pattern offers excellent off-axis rejection, ensuring that only the desired sound is picked up, making it an excellent choice for noisy environments or multi-instrument setups. The SM27 also includes an integrated 3-position switchable low-frequency filter to reduce background noise and manage proximity effect, as well as a 15dB pad to handle high SPL sources with ease.

Designed to withstand the rigors of constant use, the sturdy metal construction of the SM27 is complemented by three separate mesh layers to minimize wind and breath noise, ensuring clear and consistent audio reproduction. Whether you're recording vocals, acoustic instruments, or amplified sound sources, the Shure SM27 offers unparalleled versatility and reliability.
