- NEUMANN KM 143A nx
Description
The combination of the capsule KK 143 with the analog output stage KM A is only one of the numerous options within the modular Neumann KM A/D small diaphragm microphone system. Eight different small diaphragm capsules (KK 120 up to KK 185) may be combined with either an analog output stage (KM A) or a digital AES 42 output stage (KM D). A comprehensive range of accessories ensures adaptability to the most diverse fields of application.
The KK 143 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.

- directional characteristic: wide-angle cardioid
- part of the modular microphone system KM A/D
- comprehensive range of accessories
