Neumann KM-184 Miniature Cardioid Condenser Microphone
The KM 184 (cardioid) in particular has become the classic high-quality miniature microphone. Now also available in attractive stereo sets, with cardioid, hypercardioid or omni directional characteristics. 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. 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 "Series 180" microphones have 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 "Series 180", as in all Neumann microphones, is balanced and phantom (48V) powered. 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 KM 184 delivery includes a WNS100 windscreen and SG21/17 stand mount. Microphone available in either nickel or black matte finish - please specify upon ordering.
