The Neumann KMR 82i is a long range shotgun microphone. Due to its low power consumption and its low sensitivity to wind and handling noise, the KMR 82i is perfect for Location Sound Work. It is a shotgun microphone with a very high directivity for situations that require the microphone to be kept at a greater distance from the source. This is often the case in electronic news gathering (ENG) and in theaters, where microphones ought to remain invisible.
The KMR 82i combines a pressure gradient condenser capsule with a long interference tube to achieve a very narrow acceptance angle of 45°, so off-axis sound is picked up at reduced level but without unwanted coloration. The KMR 82i therefore sounds perfectly natural for a long shotgun microphone and is easy to combine with other microphones, without unwanted side effects.
The Neumann KMR 82i offers very low self-noise of only 12 dB-A and a high sensitivity of 21 mV/Pa. It can handle high SPLs of up to 128 dB without audible distortion. For use at shorter distances, the filter frequency can be shifted to 120 Hz using the low cut switch to compensate for the proximity effect, a second switch activates an electronic filter which compensates for the capsule's treble boost.
