The origins of Microtech Gefell are intertwined with the legacy of Georg Neumann and the invention of the first condenser microphone. Microtech Gefell grew out of the original Neumann factory that relocated to Gefell in 1943 during World War II. The current Gefell condenser microphones are manufactured using the original techniques and exclusive processes developed by Georg Neumann. Microtech Gefell carries the torch ignited by designs like the classic M7 capsule through their own innovations, including the M 300 and M 930, and UM 92.1 microphones.
