Neumann KM 183 Omnidirectional Microphone - Microphone

Neumann KM 183 Omnidirectional Microphone is a precision omnidirectional stage microphone that offers transparent capture across a wide band, and is ideal for professional live and studio work.

This compact microphone covers a frequency range from 20 to 20,000 Hz, reproducing sources with natural detail and very low coloration. The KM 183’s omnidirectional polar pattern ensures uniform pickup around the capsule, making it an excellent choice when consistent room or ensemble capture is required.

Designed as a stage/performance microphone, the KM 183 weighs only 80 g and measures 107 mm in height with a 22 mm depth, making it easy to position on stands and unobtrusive in live setups. The nickel finish gives it a professional, durable appearance suited to touring and studio environments.

Electrical performance is engineered for reliability: the microphone has a 50 Ω input impedance and a very low total harmonic distortion (THD) of 0.5%, delivering clear, accurate reproduction even at higher levels. Connectivity is wired to guarantee stable signal transfer for critical applications.

Power consumption is minimal at 3.2 mA, so the KM 183 integrates cleanly into existing wired setups without demanding extra power. Its specification and build quality make it suitable for capturing acoustic instruments, choirs, ambient room sound, and broadcast applications where neutrality and detail matter.

Typical use cases include overheads for drums, ensemble and choir capture, ambient room miking for acoustic instruments, and on-stage reinforcement where an unobtrusive omnidirectional pickup is preferred. Its low weight and compact dimensions also make it a great option for portable recording rigs.

Key selling points are its full 20–20,000 Hz frequency response, omnidirectional pattern for even spatial capture, low THD (0.5%), and robust nickel finish. The wired connectivity and low power draw ensure dependable performance in both live and studio situations.
