The legendary SM81 is an industry-standard, flat-response cardioid condenser microphone, featuring a wide frequency response and low self-noise.

What is the SM81 best suited to?
The SM81 is the perfect choice for a professional musician or sound engineer who is looking to mic up 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.

What characteristics can I expect when using an SM81?
The SM81 has a flat response curve for accurate reproduction of the sound source and can also be modified via a bass roll off switch. The 0dB/10bB lockable attenuator switch gives you even more flexibility when miking up loud sound sources and it has a cardioid polar pattern which isolates the main sound source while minimizing handling noise.
