The Neumann KM 184 MT is a stereo set of miniature condenser mics with a black finish and cardioid polar pattern. A member of Neumann's Series 180 mics, it's optimized mechanical construction and conscious omission of modularity make the KM 184 ideal for for economy-minded production and home recording studios.

Electrical features
The Series 180 microphones have the same transformerless circuitry as Neumann uses in the KM 100 system, resulting in excellent technical specifications:

Compared to the KM 84, the dynamic range of the KM 184 is increased by 24dB mainly through the reduction of self-noise level to only 22dB (CCIR) and an increased sound-pressure handling capability of up to 138dB.

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.

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 you expect from Neumann microphones.
