Neumann KM 183 Pressure Gradient Transducer Microphone, Nickel
The Neumann KM 183 Omnidirectional Mic is 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.
The Neumann KM183 features 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. The KM 183 has the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications.
The Neumann KM 183 is a good choice for all users who look for a high-quality miniature microphone, but do not need the complex, modular KM 100 system, which continues to be part of the Neumann product range.
The mechanical construction was simplified, for example, capsule and output stage cannot be separated from each other. For this reason the Neumann KM183 is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
