The satin nickel KMR 82 i Shotgun
Microphone from Neumann uses a combination of a pressure gradient
transducer and an interference tube. If the wavelength of the frequency
is longer than the tube length, the microphone works as a pressure
gradient transducer. At higher frequencies, it operates as an
interference transducer for lateral sound.
Off axis sound sources
are picked up with reduced level, but without coloration. Therefore,
the microphone is well suited to record individual instruments of an
orchestra. The pickup areas of several shotgun microphones may even
overlap as, for example, during recordings on a large stage, without
causing any problem.

The KMR 82 is
less sensitive to wind and pop noise when compared to the KM 150
miniature microphone with a similar high directivity. The shotgun
microphone features extremely low self noise, good impulse response, and
high output level.
