Neumann KM 183 Stereo Set Black

KM 183 and the 180 Series: Neumann Neutrality in a Compact Format

Designed to meet recording needs where faithful reproduction is sought, the KM 183 belongs to the 180 Series: an approach focused on transparency, polar pattern consistency, and studio reliability. Despite its accessible positioning, it incorporates demanding Neumann engineering, which has become a benchmark for professional setups oriented towards "sound truth."

A Universal Studio Microphone, from ORTF Stereo to Large Ensemble Recordings

The KM 183 excels whenever it is necessary to capture an instrument or ensemble without coloration: piano, acoustic guitar, strings, percussion, choirs, woodwinds, and brass. Its omni-directionality and excellent off-axis behavior facilitate stereo pairs and surround setups, while remaining visually discreet for broadcast, TV, and radio applications.

Transparency, Dynamics, and Consistency: Key Design Points

"Constant" Omnidirectional for a Cleaner Image

Its omnidirectional pattern is designed to remain uniform over a wide frequency range, which limits timbre variations when the source moves or when multiple microphones "see" each other. The result: better clarity of layers and easier stereo alignment.

Equalization Designed for the Diffuse Field

The capsule is optimized for a balanced response in the diffuse field. In free field, there is a slight high-frequency boost (about 7 dB around 10 kHz) that adds air and detail without sacrificing naturalness, useful for close miking.

Low Noise and High Headroom

With very low self-noise and high SPL capability, the KM 183 handles loud sources effortlessly while remaining relevant on the most subtle passages. Its low-impedance output stage is also an advantage for setups with long cables, maintaining stable transmission.
