The MM 2 is the first measurement microphone manufactured by Georg Neumann GmbH from 1949 to 1954. The microphone derives from the U 47 using the same body and circuit with some modifications and a Telefunken VF 14 M tube. A long neck connects the capsule to the microphone body to avoid sound field perturbation and reflections. A 10 mm calibrated MM 2 small aluminium diaphragm pressure capsule is placed at the neck’s top. The MM 2 uses the same PSU and cables as the U 47 and U 48 microphones. A pistonphone machine was manufactured for measurement microphone calibration. The frequency response was 30 -16,000 Hz +/- 1 d B.
