The MM 1 is a flexible condenser measurement microphone for acoustic measurement of studio rooms, PA and ELA systems, and for monitoring sound pressure levels. The measurement microphone has also made a name for itself in research, development and industry. Equipped with a high-quality back electret condenser capsule, the diffuse-field equalized microphone has a linear frequency response at 90°.

The MM 1 is manufactured by hand within extremely tight tolerances at the company's site in Heilbronn, Germany.
