SM81 Instrument Microphone

The Shure SM81 is a high-quality, unidirectional condenser microphone designed for studio recording, broadcasting, and sound reinforcement.  Its wide frequency response, low noise characteristics, and low RF susceptibility have made it a standard for applications involving acoustic instruments, especially guitar, piano, and cymbals.

The SM81 is ruggedly constructed.  It operates on phantom power and performs over a wide range of temperatures and humidity conditions.  It is furnished with a swivel adapter, attenuator-switch lock, foam windscreen, and case for carrying and storage.
