Specifications

Cartridge Type: Condenser (electret bias)
Frequency Response: 50 to 20,000 Hz
Polar Pattern: Supercardioid
Output Impedance: Rated at 150 ohms (100 ohms actual +/- 20%); recommended minimum load impedance: 800 ohms
Sensitivity (at 1,000 Hz): Open Circuit Voltage: -52.5 dBV/Pa (2.4 mV); (1 Pa = 94 dB SPL)
Clipping Level (at 1,000 Hz): 1000 ohm Load: -6 dBV (0.5 V)
Maximum SPL (at 1,000 Hz): 140.5 dB (0.25% THD, 1000 ohm load)
Self-Noise (equivalent sound pressure level; measured with true rms voltmeter): 24 dB typical, A-weighted; 26 dB typical, weighted per DIN 45 405
Dynamic Range: 116.5 dB (maximum SPL to A-weighted noise level)
Signal-to-Noise Ratio: 70 dB at 94 dB SPL (IEC 651)* -- *S/N ratio is difference between 94 dB SPL and product's equivalent self noise (SPL A-weighted).
Polarity: Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3.
Power: Phantom Supply Requirement: 11 to 52 Vdc, positive at both pins 2 and 3.
Current Drain: 1.0 to 1.2 mA
Connector: Three-pin (XLR) professional audio.
Case: Aluminum construction with steel grille and satin black finish.
Weight: 7 ounces
