The narrow shape and transmission characteristics make the KM184 suitable for a good range of tasks in the radio and television secto as well as recording studio.The KM 184 is the successor of the well proven KM 83 and KM 84 which have been used since the seventies worldwide with great success.
The pressure gradient transducer KM 184 features very smooth frequency responses not only for the 0-degree axis, but also for lateral (off-axis) sound incidence. In typical usage, there is no coloration of sound over a wide pickup angle which makes this mic suitable for recording situations when it is necessary to attenuate off-axis sound (mainly from the rear) from other nearby instruments. This makes the KM184 very useful for spot mic's, overhead's, close miking of strings, wind instruments, percussion, piano, Leslie speakers, guitar amps and more.
Although the KM 184 has the same capsule as the KM 84, the microphone differs slightly on the 0-degree 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. Apparently this difference was achieved with just a slight change of the capsule's rear opening, and is not due to resonances.
