Specifications:

Type: Condenser, electret bias with integrated preamplifier
Frequency Response: 40 to 20,000 Hz
Polar Pattern: Unidirectional (cardioid)
Output Impedance (at 1kHz): Rated 150 Ohms (actual) (Tolerates loads as low as 150 Ohms with reduced clipping level)
Output Level (at 1 kHz; 0 dB = 1 V/Pascal): –54.5 dB (1.9 mV)
Signal to noise ratio (ref. A-weighted noise): 63.0 dB at 94 dB SPL (IEC 651)
Output Clipping Level (at 1000 Hz): 2.5KOhm Load: -8 dBV (0.4V), 1 KOhm Load: -8 dBV (0.4V)
Maximum SPL: 2.5KOhm Load: 142 dB, 1 KOhm Load: 142 dB
Dynamic Range (max. SPL to A-weighted noise level): 111 dB
Output Noise (equivalent SPL): 31 dB (typical, A–weighted)
Recommended Operating Voltage: 11–52 VDC Phantom power
Polarity: Positive sound pressure on the diaphragm produces positive voltage on pin 2 relative to pin 3 of preamplifier output connector
