The SM81�s flat 20-20k response makes it supremely accurate in its reproduction of audio sources. A 3-position bass roll-off switch reduces low-end energy, thus suiting the 81 to any acoustic environment. Additional features include a 10dB attenuator, cardioid pattern, and replaceable condenser capsule. Excellent for acoustic guitar/bass, cymbals, live recording, piano, orchestra, strings, sampling, woodwinds, and stereo pickup.

• 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
