378M33 четверть-дюймовая микрофонная система

The Audio Precision model 378M33 is recommended for extreme accuracy applications where high frequency measurements or high acoustic amplitude measurements are required. The 378M33 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 10-32 coaxial (microdot) jack.
