The Neumann AK 30 microphone capsule is part of the KM 100 miniature series. The diaphragm has an omnidirectional polar pattern.
The AK 30 features a pressure gradient, single diaphragm transducer with an omnidirectional polar pattern.
The AK 30 is a diffuse-field equalized pressure transducer with a free-field treble boost (approx. 7 dB at 10 kHz). The frequency response in the diffuse sound field is flat up to 10 kHz. The microphone is best applied as a spot microphone for piano, wind instruments, strings, percussion and drums, room ambiance capturing or stereo recording.
The pressure gradient element provides an omnidirectional pattern providing even frequency response and output levels.
