Neumann KMR 82I, Long shotgun (16 in) with case and MZW 67

The nickel color Neumann KMR 82I is a shotgun microphone that uses a combination of a pressure gradient transducer and an interference tube. If the wavelength of the frequency is longer than the tube length, the Neumann KMR 82I microphone works as a pressure gradient transducer. At higher frequencies, the Neumann KMR 82I operates as an interference transducer for lateral sound. Off axis sound sources are picked up with reduced level, but without coloration. Therefore, the Neumann KMR 82I microphone is well suited to record individual instruments of an orchestra. The pickup areas of several shotgun microphones may even overlap as, for example, during recordings on a large stage without causing any problem.

CLEAR AND FOCUSED SOUND FROM A DISTANCE

The KMR 82 i 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 82 i can also be used to obtain a clear and focused sound in noisy environments.

Technically speaking, the KMR 82 i combines a pressure gradient condenser capsule with a long interference tube to achieve a very narrow acceptance angle of 45˚ and excellent rejection of unwanted sound. Unlike many other shotgun microphones, the Neumann KMR 82 i’s lobe shaped pickup pattern is frequency-independent. In other words, off-axis sound is picked up at reduced level but without unwanted coloration. The KMR 82 i therefore sounds uncommonly natural for a long shotgun microphone and is easy to combine with other microphones, without unwanted side effects.

Compared to other shotgun microphones, the Neumann KMR 82 i offers a superior sound balance. Its frequency response is highly linear up to 2 kHz, while a broad treble lift compensates for high frequency losses that occur when recording at greater distances. The KMR 82 i 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. A high pass filter suppresses subsonic interference, such as wind and handling noise. 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. To avoid sibilance problems in cases when the KMR 82 i is used for close speech, a second switch activates an electronic filter which compensates for the capsule’s treble boost.
