Neumann KM183 Small Diaphragm Omnidirectional Condenser Microphone – Nickel Overview:

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.

Electrical features
The “Series 180” microphones have the same transformerless circuitry as is used in the KM 100 system.

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

Economy
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.
