Shotgun Microphone |  
| 
 Product Code: KMR81D

| 
| 
| 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.

| � Interference 
tube microphone with shotgun directional characteristic � Interference/pressure-gradient transducer
 � High lateral and back 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 no 
longer needed. This also means space and weight savings (e.g. in the OB van).
