The KMR 81 D is the transition of 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 the advantages of the digital circuit technology, such as extended dynamic range, a more robust operation (EMC safe) and the avoidance of clipping as a result of the integrated peak limiter/compressor.

The settings for all functions can be recalled, set and stored in the microphone by using one of the digital microphone interfaces.

Neumann KMR 81 D Features:

  • Free of coloration
  • Interference tube microphone with shotgun directional characteristic
  • Interference/pressure-gradient transducer
  • High lateral and back (off-axis) attenuation
  • 90°-recording angle
  • Extensive accessories for outdoor use
  • Light weight: 90 g
  • The legendary Neumann sound in the digital realm. Pure Neumann capsule sound
  • The satisfaction of recording the uncolored original, with no "bottlenecks" between the capsule and the recording system
  • The guarantee of having one of the best A/D converters available
  • Anti-clipping processing ensures handling safety, and reduces stress
  • Reduced time requirements and personnel costs, particularly due to faster post production processing
  • Lower investment costs, since separate A/D converters and preamps are nolonger needed. This also means space and weight savings (e.g. in the OBvan)
