discontinued Cardioid Pencil Condenser Microphone

Neumann KM-84

Description

The KM-84 was the world’s first phantom-powered microphone. It was built to run on 48v DC, and designed to be as small as possible; the model name ‘KM’ stands for “Kleine Mikrofon” (small microphone).

Although discontinued (in some sense replaced by the KM-184), the KM-84 remains a favorite of vintage mic enthusiasts for drum overheads and hi-hat applications.

The mic is known for having an exceptionally flat frequency response.

The Neumann KM-84 is also known as: KM84.

The mic was released in 1966.
