Neumann KM 183 Omnidirectional Small-Diaphragm Condenser Microphone – Nickel

Neumann KM 183 Omnidirectional Small-Diaphragm Condenser Microphone

The Neumann KM 183 is a professional small-diaphragm condenser microphone from the acclaimed Neumann Series 180. Designed for applications where absolute sonic transparency is essential, the KM 183 features a frequency-independent omnidirectional polar pattern, delivering exceptionally natural sound reproduction with virtually no off-axis coloration. Its combination of low self-noise, high SPL handling, and transformerless electronics has made the KM 183 a trusted choice for professional studios, broadcast facilities, live productions, and location recording worldwide.

Unlike modular KM A and KM D systems, the KM 183 is a fixed-configuration microphone, providing the renowned Neumann performance in a cost-effective and compact design. Its pressure transducer capsule offers an unlimited low-frequency response, while diffuse-field equalization ensures an exceptionally balanced sound in reverberant environments. This makes the KM 183 ideal for capturing acoustic instruments, orchestras, choirs, ambient recordings, and immersive stereo or surround microphone arrays.

Natural Omnidirectional Sound Reproduction

The KM 183 employs a pressure transducer capsule with a highly uniform omnidirectional pickup pattern. Its frequency-independent polar response captures sound evenly from every direction without introducing tonal coloration, preserving the natural acoustic character of instruments and recording spaces. In free-field applications, the capsule incorporates a gentle high-frequency boost that contributes to exceptional detail and clarity while maintaining accurate overall tonal balance.

Series 180 Professional Performance

The Series 180 consists of three microphones with different directional characteristics: the KM 183 (omnidirectional), KM 184 (cardioid), and KM 185 (hypercardioid). Built using Neumann's transformerless circuitry, the KM 183 delivers a wide dynamic range, outstanding transient response, and exceptionally low self-noise while maintaining reliable performance in demanding recording environments. Its compact design also makes it visually unobtrusive for television, film, and live performance applications.
