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
