Seven ampere meters that had been left behind were transformed to voltmeters and sold by Jorg to Siemens. This telecom mogul then asked Sennheiser if he could produce 200 copies of a special microphone designed for radio, that Siemens former supplier Henry Radio, from Vienna, was unable to deliver since their factory lay in ruins.Sennheiser and seven former colleagues undertook the job, using machinery that had not been removed. Copying the microphone turned out to be very labour intensive since the design needed to be followed exactly, otherwise the sound quality detoriorated. (English)

The DM1 was an exact copy of the Henry Radio HM 1; a dynamic omni. Like the original it bore no marking other than a serial number. The frequency range was 30-10.000 Hz, in later years the original impedance of 25 Ohms was changed to 200 Ohm to better suit more modern radio equipment. (English)
