Effective output level -53.8 dBm (0dBm = 1 mW/10ju bar, 1,000 Hz) Open circuit voltage 0.2mV/u bar, at 1,000 Hz
Output level diviation ±2dB Recommended load impedance is more than 3
Approx. 134dB SPL
Approx. 106dB
NOISE LEVEL Signal-
to-noise Ratio: More than 46 dB (1,000 Hz, 1 jubar)
Inherent Noise: Less than 28 dB SPL (0 dB SPL = 2x 10-4 ubar) Less than 40dB SPL
Wind Noise *1: Less than 5 dB SPL/m gauss
Induction Noise From *1 Wind noise is the value measured by External Magnetic applying a wind velocity of 6.6ft/second from all
Field *2: directions on the microphone. The mean value is obtained and converted to the equivalent input sound level. 0dB = 2x10-4 ubar
*2 The external magnetic field
induction noise is measured by placing the microphone in an alternating magnetic field of 50 Hz, 1 m gauss. The maximum noise value is measured and then converted to the equivalent input sound level. 0dB = 2x 10-4 ubar
