If the wavelength of the frequency is longer than the tube length, the microphones work as pressure gradient transducers. At higher frequencies they operate as interference transducers for lateral sound. Off-axis sound sources are picked up with reduced level, but without coloration.\u003cbr\u003e\u003cbr\u003eTherefore, 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.\u003cbr\u003e\u003cbr\u003eThe KMR 81 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.\u003cbr\u003e\u003cbr\u003ePolar Patterns\u003cbr\u003eThe KMR 81 is a shotgun microphones with a very directional characteristic.\u003cbr\u003e\u003cbr\u003eThe 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 81 has a frequency independent directivity within a pickup angle of 90° for audio signals that determine the tonal balance of the program material.\u003cbr\u003e\u003cbr\u003eFilter and Attenuation\u003cbr\u003eThe microphone has a 10 dB attenuation switch to prevent the input of the following unit from overloading.\u003cbr\u003e\u003cbr\u003eA second switch activates a 200 Hz high-pass filter. Toward the lower frequencies the sensitivity of the microphone is attenuated by approximately 15 dB at 50 Hz. The frequency range above 200 Hz is unaffected.\u003cbr\u003e\u003cbr\u003eUse on Location\u003cbr\u003eThe shotgun microphone features very high output capability and a remarkably low self-noise level.\u003cbr\u003e\u003cbr\u003eIts low power consumption, light weight, and low sensitivity to wind and handling noise, makes it an ideal tools for news gathering on location.\u003cbr\u003e\u003cbr\u003eSmall dimensions, together with a balanced center of gravity, make handling easy without any whiplash effect.\u003cbr\u003e\u003cbr\u003eHowever, 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.\u003cbr\u003e\u003cbr\u003eFor mobile use a handle and an elastic suspension are available.","brand":"Neumann","offers":[{"title":"Default Title","offer_id":44449228980327,"sku":"11140","price":1795.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/neumann-kmr-81i_11140_1.jpg?v=1787088224","url":"https:\/\/vintageking.mom\/products\/neumann-kmr-81i-shotgun-microphone-nickel","provider":"Vintage King","version":"1.0","type":"link"}
