{"product_id":"neumann-u-89-i-14288","title":"Neumann U 89 i","description":"The Neumann U 89 i is a studio microphone for general-purpose applications. The grille protects a dual-diaphragm capsule. A rotary switch beneath the grille selects five different polar patterns. The microphone can therefore easily be adapted to large sound sources, widely separated sources, or sound sources to be recorded from a great distance. The amplifier accepts sound pressure levels of up to 134 dB without distortion. This figure can be increased to 140 dB. An additional rotary switch activates a filter that changes the frequency response at low frequencies or below 80 Hz or 160 Hz. \u003cbr\u003e\u003cbr\u003eAPPLICATIONS\u003cbr\u003e\u003cbr\u003eThe U 89 i is similar in appearance to the U 87. It is smaller in size and lighter in weight. It offers five, instead of three, polar patterns and a higher maximum sound pressure level, making this microphone more easily adaptable to different applications. \u003cbr\u003e\u003cbr\u003ePOLAR PATTERNS\u003cbr\u003e\u003cbr\u003eIn addition to the usual polar patterns: omnidirectional, cardioid, and figure-8, we have added a hypercardioid and a subcardioid pattern. When compared with the standard cardioid polar pattern, the hypercardioid pattern suppresses sound from the sides more effectively. The subcardioid polar pattern is especially useful for recording large sound sources. \u003cbr\u003e\u003cbr\u003eACOUSTIC CHARACTERISTICS\u003cbr\u003e\u003cbr\u003eThe microphone is directional from the front, marked with the Neumann logo. The large-diaphragm capsule has a very flat frequency response for all polar patterns over a wide acceptance angle. The frequency response curves are flat up to 10 kHz within a pickup angle of ± 100°. As a result, the U 89 i has a very uniform diffuse-field response for all polar patterns. This is important in a reverberant environment, when more reflections reach the microphone capsule. The acoustic information is not affected in its tonal quality when recorded by the microphone. This characteristic is achieved without resorting to corrective resonance effects. The capsule is elastically mounted to prevent any structural noise that could interfere with its operation. \u003cbr\u003e\u003cbr\u003eFILTER AND ATTENUATION\u003cbr\u003e\u003cbr\u003eThe amplifier supports sound pressure levels of up to 134 dB without distortion. With a self-noise level of 17 dB (A-weighted), the total dynamic range is 117 dB. The maximum sound pressure level is 140 dB when the –6 dB rotary switch is in the ON position. A low-frequency attenuator at 80 Hz or 160 Hz can be activated with the third rotary switch beneath the grille. This filter suppresses low-frequency interference, however, it maintains a constant frequency response for foreground sound sources, for example, when the proximity effect could negatively affect the program material. An abrupt high-pass filter in the LIN position prevents the microphone's output transformer from being overloaded due to unwanted subsonic frequencies.","brand":"NEUMANN","offers":[{"title":"Default Title","offer_id":57310532862283,"sku":"006499","price":2699.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/0955\/7067\/files\/u_89_i_8b89fe55-fdc9-4367-84d3-9193e7e51cab.jpg?v=1779190008","url":"https:\/\/microfusa.com\/en\/products\/neumann-u-89-i-14288","provider":"microFusa","version":"1.0","type":"link"}
