Features

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. Other accessories are available.

Shure SM81 Instrument Microphone Features:
  • 0 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
  • Phantom powering (DIN 45 596 voltages of 12 to 48 Vdc)
  • Rugged steel construction for durability
  • Field-usable over wide range of temperature and humidity conditions
