Shure SM81-LC

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.

• 20 Hz to 20 kHz frequency response

• Flat response curve for accurate reproduction of sound sources

• 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

• Type: Condenser (electret bias)

• Frequency Response: 20 to 20,000 Hz

• Polar Pattern: Cardioid (unidirectional) response-uniform with frequency, symmetrical about axis
