The SM7B dynamic microphone has a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications. It features excellent shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices. In addition to its standard windscreen, it also includes the A7WS windscreen for close-talk applications.
Frequency Response: 50 to 20,000 Hz
Polar Pattern: Cardioid
Output Impedance: 150 Ω
Sensitivity at 1 kHz: -59 dBV/Pa (1.12 mV)
Hum Pickup: (typical, at 60 Hz, equivalent SPL/mOe) 11 dB
Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 with respect to pin 3
