Designed and manufactured by AKG at the request of Telefunken, the Ela M 251 was a 3-pattern tube mic built around AKG’s famed CK12 capsule.

Telefunken had never manufactured microphones, but instead served as the distributor — and brand name — for mics made by Neumann and AKG. Notably, the early U 47 microphone was branded by Telefunken, despite having been designed and manufactured by Neumann. When Neumann began distributing its products under its own name, Telefunken was reportedly left without a large-diaphragm condenser in its product line, and commissioned AKG to develop a replacement.
