Neumann KM 183 - Small-Diaphragm Condenser Mic (Nickel)
Neumann KM 184 Condenser Microphone (Nickel)
The Neumann KM 184 is a small-diaphragm condenser microphone. Its polar pattern is cardioid. It is available in two colorsblack matte, or nickel. The KM 184 is also available as stereo pair, matched and calibrated by the Neumann manufacturer. With their slender shapes and their transmission characteristics, the "Series 180" is especially suitable for a very wide array of tasks in both the radio and television sector. The "Series 180" consists of three different compact miniature microphones with polar patterns to satisfy the demands of all common studio applications. The tremendously successful KM 184 is cardioid. It became a standard within the global studio community in just a very short time, and was the basis for the eventual release of the KM 183 and KM 185. The KM 183 is omni-directional. The KM 185 is hyper-cardioid. The KM 183 and KM 184 microphones are the successors of the well proven KM 83 and KM 84, which have been used since the seventies worldwide with great success.  The output of the "Series 180" is, as in all Neumann microphones, balanced and phantom (48V) powered.
The "Series 180" is a good choice for all users looking for a high-quality miniature microphone, but do not need the complex, modularity of the Neumann KM 100 system, with its interchangeable capsules. 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 mechanical construction was simplified. For example, the 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.
The KM 183 is a pressure transducer with a boost of approximately 7 dB at 10 kHz in the free field. It has a flat frequency response. The pressure gradient transducers of the KM 184 and KM 185 feature very smooth frequency responses not only for the 0° axis, but also for lateral (off-axis) sound incidence. In typical usage, there is no coloration of sound over a wide pickup angle. Although the KM 184 has the same capsule as the KM 84, the microphone differs slightly on the 0° 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 KM 185 with its hyper-cardioid characteristic features attenuation of sound incidence from the side or rear of about 10 dB, with minimum sensitivity at an angle of 120°.
The "Series 180" microphones have the same transformer-less 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.
(1) For close miking of instruments when there is no need to attenuate extraneous noise, and in a balanced acoustic environment to record acoustic guitar, wind instruments, strings, percussion, drums.
(2) As a spot mic for piano, wind instruments, organ, choir
(3) As a main mic, especially for capturing room acoustics. 
(4) Ideal as AB stereo pair because of the flat frequency response in the diffuse sound field.
