The Neumann KM 184 is a small‑diaphragm condenser microphone designed for musical instruments. It uses a frequency‑independent cardioid pattern that maintains consistent off‑axis response, which helps preserve natural imaging in stereo setups and minimizes coloration in multi‑mic environments. The capsule offers a smooth, largely linear frequency response with a subtle rise around the upper treble range, contributing a bit of clarity without altering the instrument’s character. With a self‑noise rating of 13 dB‑A and the ability to handle sound pressure levels up to 138 dB, it performs well on both delicate acoustic sources and louder instruments. Its compact pencil‑style form factor makes it unobtrusive on stage or in the studio, and the transformerless output stage allows long cable runs without signal degradation. The KM 184 is commonly used for acoustic instruments, ensembles, percussion, and overhead setups where transparency and precise detail are required.
