The KMR 81 i is the Short version of the classic shotgun mic, with switchable filter and pre-attenuation. Excellent attenuation of off-axis sound (lateral and rear). Coloring absence.
Switchable Bass-Cut filter
 No
The KMR 81 is a shotgun microphone with a high directivity, remaining constant regardless of the frequency in the sound recording angle.
The advantage is that a sound source, for example an actor on the set, does not change its tonal balance when moving through the angle covered by the microphone.
