Named for the year that it was created (1949), the M49 was truly a revolution for recording engineers. Thanks to an innovative remote-controlled pickup pattern, an engineer could easily adjust the direction of the microphone without leaving the confines of the control room. This simplified way of testing out new sounds was created by Herbert Großkop and purchased by Neumann for use in the M-49.
An even more impactful element of the M49 is the sound itself. The mic features two cardioid condenser systems inside its housing, with the front remaining at a consistent 60Vdc and the back going from 0Vdc to 120 Vdc. The resulting sound features a consistent smoothness that is highlighted by heavy lows and highs that can cut perfectly across recordings.
Finding favor in the studios of 50s and 60s, the M49 was the standard microphone used on smooth pop and soulful jazz recordings during the era. Despite being used predominantly on vocals, both in the studio and in the live setting, the mic was also used for instruments, especially monumental brass and drum tracks.
Released 10 years after the birth of the Neumann M49, Miles Davis was said to have exclusively used the microphone on his best-selling album, Kind of Blue.
