The "Series 180" consists of three compact miniature microphones with patterns that satisfy the demands of all common studio applications. 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 KM 184 Stereo Set features 2x KM 184 Microphones in their own wooden case with clips to suit.
ApplicationsTheir slender shapes and the transmission characteristics described below make the "Series 180" especially suitable for a very wide range of tasks in the radio and television sector.
The 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.
he pressure gradient transducer KM 184 features 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.
