    designated as AKG C12

    Valve condenser microphone using a 6072 vacuum tube with transformer coupled output and remote polar pattern selection via external power supply.

    The original AKG C12 was introduced in the early 1950s and became one of the first large diaphragm valve condenser microphones to offer remotely selectable polar patterns. It utilised the edge terminated CK12 capsule and a 6072 vacuum tube, establishing a design that would influence numerous later studio microphones. Production continued through to 1960, during which time the C12 was widely adopted in professional recording studios and became closely associated with high end studio recording practices.
