Description
FEATURES
The Shure SM81 is a high-quality small diaphragm, cardioid condenser microphone. Its flat, neutral frequency response, make it particularly well-suited for use on acoustic guitar, piano, cymbals and choirs.
- 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 effectively isolates source signal
- Low RF susceptibility
- Selectable low-frequency response: flat, 6 or 18dB/oct roll-off
- 0dB/10dB lockable attenuator switch
- Phantom powering (DIN 45 596 voltages of 12 to 48 Vdc)
- Rugged steel construction for durability
- Field-useable over wide range of temperature and humidity conditions
