Output impedance |
600 ohms ±20 % |
Output level |
Open circuit voltage: –85 dB (0.056 mV) |
|
(0 dB=1 V/1 µbar at 1,000 Hz) |
|
Effective output level: –68.8 dBm |
|
(0 dBm=1 mW/10 µbar at 1,000 Hz) |
Noise level |
Wind noise *1: Less than 55 dB SPL |
|
Induction noise from external magnetic |
|
field *2: Less than 10 dB SPL |
*1 Wind noise is the value measured by applying a wind velocity of 2 m/sec (6.6 ft/ sec) from all directions to the microphone. The mean value is taken and converted to the equivalent input sound level.
(0 dB=2 × 10–4 µbar)
*2 The external magnetic field induction noise is measured with the microphone placed in an alternating magnetic field of 50 Hz, 1 milligauss. The maximum noise value is taken and then converted to the equivalent input sound level.
(0 dB=2 × 10–4 µbar)
