Neumann KM 184 Cardioid Condenser Microphone (Nickel)
The Neumann KM 184 is a high-quality miniature cardioid microphone that is used in professional studios all over the world. The KM 184 is useful for a variety of studio recording purposes and it is also handy for radio and television work. The KM 184 features a very smooth frequency response, capturing a detailed representation of a sound with no colouration over a wide pickup angle. This microphone comes with a nickel finish.

Although the KM 184 has the same capsule as the KM 84, the microphone differs slightly on the 0 degree frequency response: The KM 184 has a gentle rise at about 9 kHz, a characteristic that was introduced very successfully with the KM 140. The result is a tonal balance that is fresher and livelier when compared to the KM 84 with its flat frequency response in that band.
This difference was achieved with just a slight change of the capsule's rear opening, and is not due to resonances.
The Neumann KM 184 microphone has the same transformerless circuitry as is used in the KM 100 system, resulting in excellent technical specifications:
Compared to the KM 84 the dynamic range of the KM 184 increased by 24 dB mainly through the reduction of self-noise level to only 22 dB (CCIR) and an increased sound pressure handling capability of up to 138 dB.
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 184, as in all Neumann microphones, is balanced and phantom (48V) powered.
The Neuman KM 184 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 184 is an economical alternative without giving up the electroacoustic features the users expect from Neumann microphones.
