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.
Typical applications are film and video recordings, where the microphone should not appear in the picture.
The KMR 82 is very often used on stage.
Therefore, the microphones are 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.
The KMR 82 is less sensitive to wind and pop noise when compared to the KM 150 miniature microphone with a similar high directivity. The shotgun microphone features extremely low self noise, good impulse response, and high output level.
The microphone capsule is positioned inside a housing tube that is acoustically open but has a high flow resistance. The directional pattern of the microphone is lobe shaped. The attenuation of lateral sound is practically independent of the frequency. The KMR 82 has a frequency independent directivity within a pickup angle of 45° for audio signals that determine the tonal balance of the program material.
The KMR 82 has a high-pass filter to suppress subsonic interference. The cutoff frequency may be raised to 120 Hz ( - 3 dB) with a built-in two-position slide switch.
Its low power consumption, light weight, and low sensitivity to wind and handling noise, makes it an ideal tool for news gathering on location.
Small dimensions, together with a balanced center of gravity, make handling easy without any whiplash effect.
However, when on location and during strong wind conditions, we recommend using an additional wind screen (included as standard accessory). The wind screen is made of polyurethane foam and also serves as soft padding of the microphone in its leather carrying case.
For mobile use a handle and an elastic suspension are available.
