Polar Pattern
Cardioid

Output Impedance
150 Ohms at 1 kHz
Recommended minimum load impedance: 600 Ohms

Sensitivity (at 1,000 Hz)
Open Circuit Voltage: -50 dBV/Pa (3.15 mV)
(1 Pa = 94 dB SPL)

Output Clipping Level
1000 Ohm Load at 1,000 Hz: +3 dBV (1.41 V)

Maximum SPL (at 1,000 Hz)
1000 ohm load (1% THD): 147 dB

Self-Noise
23 dB typical, A-weighted

Dynamic Range (1000 ohms)
124 dB (maximum SPL to A-weighted noise level)
Signal-to-Noise Ratio

71 dB at 94 dB SPL (IEC 651)*
*S/N ratio is difference between 94 dB SPL and equivalent SPL of self-noise A-weighted.
