Neumann KMR 81 D


The Neumann KMR 81 D takes the well-established KMR 81 i shotgun microphone into the digital domain. It provides all of the features of its analog counterpart, which made it a favorite of sound engineers in movie and documentary productions. Additionally, it offers all the advantages of the digital technology, such as an extended dynamic range, a more robust operation (EMC safe) and clipping protection by means of the integrated peak limiter/compressor.


Using the DMI-2 or DMI-8 digital microphone interface together with the Remote Control Software (RCS), any pre-programmed settings may be stored in the microphones.


  • Shotgun microphone for medium distances

  • Lobe shaped pattern with 90° pickup angle

  • High directivity without off-axis coloration

  • Integrated A/D converter, DSP functions
