The Neumann AK 43 microphone capsule is part of the KM 100 miniature series. The diaphragm has a wide-angled cardioid polar pattern.
The AK 43 is a pressure gradient transducer with wide-angle cardioid characteristic. Attenuation: 4 dB at 90°, 8 dB at 135°, and 11 dB at 180°. The frequency response for sound sources within an angle of ± 90° (off axis) is parallel up to 12 kHz.
The pressure gradient element provides a wide-angled cardioid pattern. Attenuation at 90 degrees is 4dB, at 135 degrees it is 8dB and at 180 degrees it is 11dB.
