The KM 183 is the successor of the proven KM 83 mic, which has been used all over the world with great success since the seventies.
The Neumann KM 183 microphone has 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 KM 183, as in all Neumann microphones, is balanced and phantom (48V) powered.
The Neuman 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 KM 183 is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
