The "Series 180" consists of three compact miniature microphones with patterns that satisfy the demands of all common studio applications.

Because of its optimized mechanical construction and conscious omission of modularity, which is unnecessary in many cases, the "Series 180" is predestined for economy-minded production and home recording studios.

The KM 183 omnidirectional 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. All "Series 180" microphones are available with either matte black or nickel finish.

Acoustic features

The KM 183 microphone is the successor of the well proven KM 83, which has been used since the seventies worldwide with great success.

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. In typical usage, there is no coloration of sound over a wide pickup angle.

Electrical features

The "Series 180" microphones have the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications.

The microphones operate without any problems, even if the input of following equipment happens to be unbalanced, for example as in some DAT recorders.

The output of the "Series 180", as in all Neumann microphones, is balanced and phantom (48V) powered.


The "Series 180" 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 "Series 180" is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
