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.
