The K 49 capsule  – well-known from the legendary U 47 and M 49 microphones – is followed  by a tube functioning as an impedance converter. In contrast to earlier  concepts – utilizing a transformer – the tube is complemented with a  transformerless output circuit design. The M 149 Tube can thus feed long  microphone cables without any coloration.\u003cbr\u003e\u003cbr\u003eTwo slide switches are  located below the large, acoustically very open headgrille. The switch  at the front allows selection of one of nine directional patterns. The  slide switch at the rear operates a seven-step high pass filter. It  allows a very fine adjustment of the cut-off frequency.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003cbr\u003eThere are nine polar patterns to choose from, making this microphone an ideal choice for a wide range of recording situations.\u003cbr\u003e\u003cbr\u003eAs  its ancestors, the M 149 Tube is a superb vocalist microphone, not only  because of the capsule, but also due to its modern circuitry,  characterized by extremely low noise level.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAcoustic Features\u003c\/strong\u003e\u003cbr\u003eThe  M 149 Tube is addressed from the front, marked with the Neumann logo.  Also on the front is the switch for the selection of the polar  patterns. \u003cbr\u003e\u003cbr\u003eThe capsule is mounted elastically inside the  headgrille to eliminate structure borne noise. The surface below the  capsule is shaped like a cone to disperse any reflected sound from the  acoustic upper half space. This avoids any interference with the primary  sound arriving at the capsule directly. \u003cbr\u003e\u003cbr\u003eA large headgrille surrounds the capsule. It is acoustically very open and therefore increases the sonic realism.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePolar patterns\u003c\/strong\u003e\u003cbr\u003eThe  polar pattern switch selects one of nine directional patterns:  omnidirectional, wide-angle-cardioid, cardioid, hypercardioid, figure-8,  and one additional intermediate pattern between each major position. \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eElectrical features\u003c\/strong\u003e\u003cbr\u003eThe  circuit of the M 149 Tube microphone has been developed to exceed  traditional designs. We have selected a modern tube (triode) and  combined its exceptional transmission characteristics with the  advantages of our proven transformerless output circuit. \u003cbr\u003e\u003cbr\u003eThe aim was to provide a more controlled environment for the audio signal on its path from the capsule to the output section. \u003cbr\u003e\u003cbr\u003eThe  final stage is an integrated amplifier, especially designed for such  applications. It features very low distortion (THD \u0026lt; 0.002 % at ± 10  V), very low self-noise, and high output current capability. \u003cbr\u003e\u003cbr\u003eAs a  result, the tube circuit is completely decoupled from the microphone  output and its characteristic response curve will be unaffected by very  high signal levels or varying load conditions. \u003cbr\u003e\u003cbr\u003eThe lower output  impedance and higher output current capability allow cable lengths up to  300 m (1000 feet) without any degradation of the audio signal. \u003cbr\u003e\u003cbr\u003eThe  tube amplifier changes the high impedance of the capsule and adds 10 dB  of gain to the audio signal, providing optimum operating  specifications. The wide dynamic range is impressive, as peak output can  be ±10 V, at 20 mA. \u003cbr\u003e\u003cbr\u003eThe ideal operating point of the tube is  maintained throughout its entire life expectancy. Plate current and  filament voltage are constantly regulated. A sensor circuit monitors and  compensates for any voltage drop across the microphone cable. The tube  is heated up slowly through inverse current limiting to guarantee long  life. Optimum operating conditions are reached within a very short  time.  \u003c\/p\u003e","brand":"Neumann","offers":[{"title":"Default Title","offer_id":44449461141607,"sku":"22398","price":2950.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/8848\/5479\/files\/used_neumann_m149__80_2fd7c369-696e-473e-8974-f0322e8f67eb.jpg?v=1787089048","url":"https:\/\/vintageking.mom\/products\/neumann-m149-80-used","provider":"Vintage King","version":"1.0","type":"link"}
