378M32 полдюймовая микрофонная система

The Audio Precision model 378M32 has a flat response in applications where high frequencies (up to 40 kHz) need to be measured very accurately. As an alternative to a standard high sensitivity (50 mV/Pa) microphone, it has an enhanced upper dynamic range and doesn’t overload or saturate for measurements above 136 dB. The 378M32 is a microphone system, comprised of a prepolarized microphone capsule combined with a low-noise preamplifier. The preamp is designed to operate on ICP® sensor power, and can be used with most 2–20 mA constant current power (CCP) microphone power supplies, including the APx1701. It carries embedded TEDS calibration and identification data; the preamplifier output is available on a BNC jack.
