The Shure SM81 is a cardioid condenser instrument microphone offers a wide frequency response and low self-noise. Features include flat response curve, low noise and high output clipping level, low distortion over a range of load impedances, and low RF susceptibility.

The Shure SM81 is the perfect choice for acoustic instruments such as acoustic guitar, piano and cymbals. It can ideally be used on stage and because of its high quality is also at home in the recording studio.
