Transducer Type
Condenser (electret bias)
Frequency Response
50 to 20,000 Hz
Polar Pattern
Cardioid
Output Impedance
Rated at 150 ohms (100 Ohms actual +/- 20%)
Recommended minimum load impedance: 800 ohms
Sensitivity (at 1,000 Hz)
Open Circuit Voltage: -51 dBV/Pa (2 mV)
(1 Pa = 94 dB SPL)
Output Clipping Level
1000 Ohm Load at 1,000 Hz: -6 dBV (0.5 V)
Maximum SPL
139 dB at 1,000 Hz (0.25% THD, 1000 Ohm load)
Self-Noise
22 dB typical, A-weighted
24 dB typical, weighted per DIN 45 405
(equivalent sound pressure level; measured with true rms voltmeter)
Dynamic Range
117 dB (maximum SPL to A-weighted noise level)
Hum Sensitivity
-5 dB equivalent SPL, maximum, in a 1 mOe field (60 Hz)
Signal-to-Noise Ratio
72 dB at 94 dB SPL (IEC 651)*
*S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
Polarity
Positive pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of the output connector.
