Explore the Shure SM81-LC Cardioid Condenser Microphone

A Legendary Condenser for Studio and Stage

The Shure SM81-LC Cardioid Condenser Microphone is a trusted choice for live sound, broadcast, and studio recording. Known for its flat frequency response (20 Hz–20 kHz), rugged construction, and accurate sound reproduction, the SM81-LC is designed to capture every detail with precision.

With its uniform cardioid polar pattern, the SM81-LC provides high gain before feedback and excellent off-axis rejection, making it equally reliable on stage or in the studio. It also features a switchable low-frequency roll-off filter (flat, 6 dB/octave, or 18 dB/octave) and a lockable -10 dB pad, allowing it to handle sound pressure levels up to 146 dB SPL without distortion.

Built with vinyl-coated steel housing and stainless-steel screen, the SM81-LC ensures durability, while its low susceptibility to RF interference keeps recordings clean in challenging environments.
