The Shure Model 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.

Features:
* 20 Hz to 20 kHz frequency response
* Flat response curve for accurate reproduction of sound sources
* Low noise and high output clipping level
* Low distortion over a wide range of load impedances
* Cardioid polar pattern, uniform with frequency and symmetric about axis, providing * maximum rejection and minimum coloration of off-axis sounds
* Low RF susceptibility
* Selectable low-frequency response: flat, 6 or 18 dB/octave rolloff
* 0 dB/10 dB lockable attenuator switch
* Rugged steel construction for durability
* Field-usable over wide range of temperature and humidity conditions
