The Shure SM Microphones Series SM-87A microphone is a professional-quality, handheld condenser microphone for use in sound reinforcement, broadcasting, and studio recording installations. The SM 87A supercardioid polar pattern provides greater rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in a reverberant or noisy environment. An integral three-stage wind and pop filter protects against wind and breath noise. Its built-in shock mount reduces stand and handling noise.

Built-in wind and pop filter
Transducer element shock mounted
Rugged construction for outstanding reliability
Field-usable over a wide range of temperature and humidity conditions
Accepts a wide variety of phantom power sources, including DIN 45 596 voltages of 11 and 52 Vdc
Type Condenser
Frequency Response 50 to 20,000 Hz
Polar Pattern Supercardioid
Sensitivity (at 1,000 Hz) Open Circuit Voltage: –52.5 dBV/Pa (2.4 mV) (1 Pa = 94 dB SPL)
Impedance Rated at 150 ohms (100 ohms actual ±20%); Recommended minimum load impedance: 800 ohms
Output Clipping Level 1000 Ohm Load at 1,000 Hz: –6 dBV (0.5 V)
