The nextel black KM 184 D NX ST from Neumann is a matched, stereo pair of cardioid, pressure condenser microphones with an AES/EBU digital output and built-in A/D converter. Neumann continues to make strides in microphone technology with internal digital conversion and an AES/EBU 42 output standard that allows remote software operation with the DMI-2 digital microphone interface, or direct connection to AES inputs on digital mixers, field recorders, etc.

The capsule, polar pattern and sonic characteristics are similar to the KM 184 analog model and is intended for live sound reinforcement and broadcast as well as recording applications. The cardioid polar pattern minimizes noise and off-axis audio signal. Vocals and instruments are captured without feedback, and ambiance. The KM 184 D features a non-reflective finish.
