The Shure SM81-LC Cardioid Condenser Microphone captures the natural detail of acoustic instruments with accuracy and clarity. Its flat 20 Hz to 20 kHz frequency response, low self-noise, and consistent cardioid pickup make it a trusted choice for studio recording, broadcasting, and live sound reinforcement, particularly for acoustic guitar, piano, and cymbals.

Natural Sound with Focused Pickup

The SM81 features a uniform cardioid polar pattern that provides strong rejection of unwanted sound while minimizing off-axis coloration. Its flat frequency response preserves the character of the original performance, while low noise and low distortion help capture subtle musical details.

Flexible Control for Every Recording

A three-position low-frequency filter offers flat response, a 6 dB per octave rolloff below 100 Hz, or an 18 dB per octave cutoff below 80 Hz. These settings help control rumble and proximity effect without relying entirely on external processing. A lockable 10 dB attenuator increases headroom for louder instruments, allowing the microphone to handle sound pressure levels up to 146 dB SPL under specified load conditions.

Built for Professional Use

Rugged steel construction, low RF susceptibility, and phantom power operation make the SM81 suitable for demanding recording and performance environments. Its balanced XLR output integrates with professional audio equipment, while the supplied mounting and protective accessories support everyday studio and stage use.
