About Neumann AK 31

The Neumann AK 31 Microphone Capsule is part of the KM 100 miniature series microphone systems. It features a pressure gradient, single diaphragm transducer with an omni-directional polar pattern. It produces a flat frequency response up to 20kHz. In the diffuse field the microphone has a high frequency roll-off above 5kHz. The microphone is best applied as a spot microphone for piano, wind instruments, strings, percussion and drums, room ambiance capturing or stereo recording.

Modular Design
The capsule is developed for use with the KM100 and KM100F modular power supplies.

Omnidirectional Pattern
The pressure gradient element provides an omnidirectional pattern providing even frequency response and output levels.
