The Neumann KM184 is a state-of-the-art small diaphragm condenser microphone with a uniform, frequency-independent cardioid polar pattern. Its very natural, transparent sound with very low self-noise and high SPL capability have made the KM184 a worldwide stage and studio standard for many applications ranging from classical piano to heavy metal drums.
The Neumann 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 KM 183 is a pressure transducer with a boost of approximately 7 dB at 10 kHz in the free field. In the diffuse sound field it has a flat frequency response. The pressure gradient transducers 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.
