Neumann KMR 81 i Shotgun Microphone

Neumann KMR 81 i Shotgun Microphone

The KMR 81 i is a shotgun microphone for medium distances, e.g. for film dialogue with a clear and focused sound while the microphone is placed outside the picture. Off-axis coloration is minimized to avoid sound change when actors are moving. The KMR 81 i offers high sensitivity with low power consumption and is lightweight for easy handling.
