The Neumann KMR81i 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, an actor on stage for example, will not change its apparent tonal balance when moving within this area. 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 KMR81i has been specifically designed for electronic news gathering.
The KMR81 is a shotgun microphone with a very directional characteristic. 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 KMR81 has a frequency independent directivity within a pickup angle of 90° for audio signals that determine the tonal balance of the program material.
The microphone has a 10dB attenuation switch to prevent the input of the following unit from overloading. A second switch activates a 200Hz high-pass filter. Toward the lower frequencies the sensitivity of the microphone is attenuated by approximately 15dB at 50Hz. The frequency range above 200Hz is unaffected.
The shotgun microphone features very high output capability and a remarkably low self-noise level. Its low power consumption, light weight, and low sensitivity to wind and handling noise, makes it an ideal tools 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.
