MP401 1/4-inch free-field Microphone
MP401 is 1/4" free-field prepolarized microphone. Its small size ensures a lower interference and reverberation influence of its presence in the sound field.
MP401 conforms to IEC 61672 Class 1 standard. MP401 can make the test at up to 170 dB, which makes MP401 the best choice for high frequency and high intensity measurement.
Features:
● 1/4-inch free-field microphone
● Sensitivity (@250 Hz): 5 mV/Pa (-46 dB re 1V/Pa)
● Frequency response: 10 Hz ~ 40 kHz (±2 dB) 6.3 Hz ~ 50 kHz (±3 dB)
●Dynamic range: 35 dBA ~ 155 dB
●Polarization Voltage: 0V (prepolarized)
