Polar Pattern
Cardioid (unidirectional) response-uniform with frequency, symmetrical about axis
Output Impedance
Rated at 150 ohms (85 ohms actual)
Recommended minimum load impedance: 800 ohms (May be used with loads as low as 150 ohms with reduced clipping level)
Output Configuration and Connector
Balanced, transformer-coupled output; male XLR connector
Sensitivity (at 1,000 Hz)
Open Circuit Voltage: -45 dBV/Pascal (5.6 mV
(1 Pascal = 94 dB SPL)
Clipping Level (at 1,000 Hz)
800 ohm Load: -4 dBV (0.63 V)
150 ohm Load: -15 dBV (0.18 V)
Total Harmonic Distortion
Less than 0.5% (131 dB SPL at 250 Hz into 800 ohm load)
Maximum SPL (at 1,000 Hz)
800 ohm load: 136 dB (attenuator at 0) 146 dB (attenuator at -10)
150 ohm load: 128 dB (attenuator at 0) 138 dB (attenuator at -10)
Hum Pickup
-3 dB equivalent SPL in a 1 mOe field (60 Hz)
Self-Noise (equivalent sound pressure levels; measured with true rms voltmeter)
16 dB typical, A-weighted
19 dB typical, weighted per DIN 45 405
