The Neumann KK 143 nx Capsule Head is compatible with the KM A and KM D series output stages to make a complete microphone.
It features a wide-angle cardioid pickup pattern to picks up sounds from every direction but with less amplitude.
The frequency response for sound sources is within an angle of 90 degrees (off-axis), and a LC4 cable can be used to keep the detached head connected to the KM A/D.
