Special Order ItemThis item is not stocked and needs to be ordered from the manufacturer. Please contact our sales team for more information.
Description
The KMR 81 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.
Features
- Interference tube microphone with shotgun directional characteristic
- Interference/pressure-gradient transducer
- High lateral and back attenuation
- 90Îç-recording angle
- Switchable filter or preattenuation features
- Extensive accessories for outdoor use
- Light weight - 145 g
Shotgun microphones are particularly useful in recording situations where a microphone cannot be positioned within the desired distance of the sound source to produce a sufficiently loud signal level. Typical applications are film and video recordings, where the microphone should not appear in the picture. The KMR 81 has been specifically designed for electronic news gathering.
