Neumann KMR 81 I MT Short Shotgun 9?€? with Twist Pack Case and WS81 Matte Black

The Neumann KMR81IMT Short Shotgun 9” with Twist Pack Case and WS81 | Matte Black is a shotgun microphone with a high directivity that remains within the acceptance angle independent of the frequency.

The advantage is that a sound source, for example an actor on stage, will not change its apparent tonal balance when moving within this area.
