Neumann KM 183 Omnidirectional Condenser Miniature Microphone
The Neumann KM 183 Miniature Microphone is a small diaphragm omnidirectional condenser pencil microphone. The KM 183 is part of Neumann's Series 180, that also has cardioid and hypercardioid models too. The KM 183's are an outstanding choice for spot miking acoustic instruments in the studio, as overheads or even location recording. All of the 180 series microphones from Neumann are available in either a black or nickel finish. The black finish is excellent for those intending to use these microphones live, to hide in the background on stage.
The KM 183 omnidirectional and KM 185 hypercardioid microphones are based on the tremendously successful KM 184 cardioid microphone, which has become a standard within the global studio community in just a very short time. All "Series 180" microphones are available with either matte black or nickel finish.
The KM 183 is a pressure transducer with a boost of approximately 7 dB at 10 kHz in the free field. In the diffuse sound field it has a flat frequency response.
