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.

Features

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.
- 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.
