Georg Neumann & Co. CMV3


03 Oct Georg Neumann & Co. CMV3

This is exceptional Andreas work on Neumann CMV 3.

The CMV designation as  to “Condensator Mikrofon Verstärker” (condenser microphone amplifier) and the number three probably indicates that two earlier prototype versions existed.  “Bottle mic,” the CMV3 had an omnidirectional M1 capsule with large, gold-sputtered colloidan (later switched to PVC) diaphragms with RE084 triode-based tube electronics.

Neumann with Erich Rickmann, founded Georg Neumann & Co. in Berlin in November 1928. This year also Neumann released the CMV3—the first  produced condenser mic.
