neumann gmbh neumann founded in 1928 and based in berlin germany is a prominent manufacturer of professional recording microphones . their best known products are condenser microphones for broadcast live and music production purposes . for several decades neumann was also a leading manufacturer of cutting lathes for phonograph disks and even ventured into the field of mixing desks for a while . contents 1 history 1.1 early years 1.2 postwar period 1.3 the end of the fifties 1.4 the sixties 1.5 the eighties and beyond 2 see also 3 external links history edit early years edit the company s original product was the cmv 3 the world s first commercially available condenser microphone . it was a rather large 40 cm tall 9 cm diameter microphone with several interchangeable capsule heads which gave it different directional patterns . because of its shape and size this microphone was often known as the neumann bottle . it is often seen in historical photographs of public events in germany through the period of world war ii . neumann s factory in berlin was damaged by allied firebombing in november 1943 . georg neumann relocated his company to the much smaller town of gefell in thuringia and resumed production at the beginning of the following year . at the close of the war thuringia fell under soviet control and the company eventually became an east german publicly owned operation i.e. a state run enterprise . after the reunification of germany the company in gefell which had continued to use the neumann name became known as microtech gefell . meanwhile georg neumann re established his company as georg neumann gmbh in one of the allied sectors of berlin and in 1949 began producing a new model of switchable pattern microphone the u 47 based on the m 7 capsule of the earlier cmv 3 series . this microphone was one of the first condenser microphones to gain widespread acceptance in the recording industry worldwide . in the united states for example the sound of the best known crooners of the 1940s e.g. bing crosby and later elvis presley had utilized the ultra smooth rolled off tone of rca ribbon microphones ; pop recordings in the 1950s e.g. frank sinatra and later the beatles on the other hand were sharper clearer much more present and more hi fi sounding as the result of using condenser microphones with elevated upper mid range response . the u 47 which was distributed worldwide under the telefunken brand name was also used for some early classical orchestral recordings in stereo . postwar period edit neumann vms70 disc cutting lathe other important microphones introduced by neumann during the immediate postwar period included the m 49 and m 50 both based on designs researched and engineered at the nwdr in germany . the m 49 used the m 7 capsule in a configuration whose directional pattern was remotely controlled the first microphone to offer such a feature . the m 50 featured a small diffuse field equalized pressure transducer embedded in the surface of a 40 mm hard plastic sphere which gave it increasing directionality above the mid range frequencies . the company also produced equipment for electroacoustic measurement including calibrated measurement microphones and chart recorders . during the period from 1953 to 1956 neumann introduced a series of small condenser microphones km 53 54 and 56 especially for use in television broadcast studios . in 1957 they introduced the sm 2 microphone which was essentially a pair of km 56 microphones in a single body arranged so that their directional patterns could be controlled remotely . the sm 2 was the world s first stereo microphone . the end of the fifties edit neumann u47 tube at the end of the 1950s the telefunken vf 14 vacuum tube on which the circuitry of the u 47 and u 48 had been based was discontinued so neumann came under pressure to develop a successor . they decided to offer all three of those two models directional patterns in a single microphone . in the meantime the rock n roll era had begun and some engineers were recording loud vocals with singers singing directly into microphones at very close range ; when the u 47 or u 48 were used in this way the result was considered by many engineers at the time to sound unacceptably harsh . this could be considered ironic since the u 47 and u 48 have a cult following today specifically for use in close up vocals with some engineers seeming to fancy that they are re creating a vintage sound whereas in fact they are creating a sound quality that was specifically abhorred by many of the golden ears of the era notable exceptions being beatles producer george martin and engineers norman smith and geoff emerick . the result was the u 67 a microphone with less emphasis in its upper midrange response giving it less of a forward tone color . the sixties edit a neumann u87 microphone in 1964 neumann developed a small cardioid capsule with considerably improved off axis linearity ; it was used in the km 64 and u 64 microphones . in 1965 neumann began to introduce solid state microphones . the first model was the ktm small cardioid later followed by the fet 70 series transistorized versions of small omnidirectional cardioid and speech cardioid microphones as well as a u 77 transistorized version of the u 67 . this series used the 12 volt a b powering system parallel powering t power or tonaderspeisung as found in nagra tape recorders and was therefore incompatible with existing studio power supplies . however standard two conductor shielded cables as were commonly used for dynamic microphones could now be used for connecting condenser microphones as well obviating the need for special multi conductor cables . in 1966 neumann adapted the phantom powering method that had been used for years in certain telephone systems so that a compatible method of powering would allow tube microphones solid state microphones and dynamic microphones all to be connected to the same power supplies . eventually the fet 80 series grew to include over a dozen models some of which are still in production as of 2014 the u 87 u 89 kmr 81 kmr 82 and usm 69 . the best known models from this series were the km 84 small diaphragm cardioid and the u 87 three pattern large diaphragm successor to the u 67 . the eighties and beyond edit in 1983 neumann began to introduce microphones with balanced outputs but no output transformer starting with the model tlm 170 . eventually this fet 100 or transformerless series was expanded to include the km 100 modular series of small microphones with seven different active capsules for various directional patterns the cardioid tlm 193 using the capsule of the u 89 and tlm 170 the small diaphragm km 180 series the large diaphragm cardioid tlm 103 the variable pattern tlm 127 and the tlm 49 cardioid vocal microphone . beginning in 1995 the company introduced a series of vacuum tube microphones with transformerless output circuitry the multi pattern m 149 tube the cardioid m 147 tube and the omnidirectional m 150 tube based on the classic m 50 design with the pressure transducer mounted in the surface of a sphere inside the capsule head . in 2003 neumann introduced their first microphone with built in analog to digital conversion the solution d d 01 . in 2006 the d 01 was followed with a modular small diaphragm series of digital microphones km d based on the km 100 180 series . in 2005 neumann began production of its first dynamic microphone the bcm 705 for the broadcast industry . neumann was acquired by sennheiser electronic gmbh in 1991 . production of neumann microphones was moved into a newly built level 100 cleanroom factory in wedemark near hannover . the company maintains its official headquarters in berlin . see also edit wikimedia commons has media related to georg neumann gmbh . list of microphone manufacturers external links edit official website mix online magazine on neumann s 75th anniversary neumann record cutting machine model sx24 neumann record cutting machine model sx24 authority control gnd 10064116 7 retrieved from https en.wikipedia.org w index.php title georg neumann & oldid 742744028 categories companies of germanygerman brandselectronics companies of germanymicrophone manufacturershidden categories commons category with local link same as on wikidatawikipedia articles with gnd identifiers navigation menu personal tools not logged intalkcontributionscreate accountlog in namespaces article talk variants views read edit view history more search navigation main pagecontentsfeatured contentcurrent eventsrandom articledonate to wikipediawikipedia store interaction helpabout wikipediacommunity portalrecent changescontact page tools what links hererelated changesupload filespecial pagespermanent linkpage informationwikidata itemcite this page print export create a bookdownload as pdfprintable version in other projects wikimedia commons languages italianopolski srpski edit links this page was last modified on 5 october 2016 at 14 34 . text is available under the creative commons attribution sharealike license ;
