Neumann KM 184 Cardioid Microphone, Nickel
The slender shape and transmission characteristics described below make the KM184 especially suitable for a very wide range of tasks in the radio and television sector. It is extremely quiet (16dB A-weighted self-noise), making it excellent for capturing the subtle nuances of acoustic guitar and orchestral perf ormances . The KM 184 microphone is the successor of the well proven KM 84, which has 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. Compared to the KM 84 the dynamic range of the KM 184 increased by 21 dB mainly through the reduction of self- noise level to only 25 dB (CCIR) and an increased sound pressure handling capability of up to 138 dB.
The microphone operates without any problems, even if the input of following equipment happens to be unbalanced, for example as in some DAT/CF recorders. The output of the KM 184, as in all Neumann microphones, is balanced and phantom (48V) powered.
The 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 this model, 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.
