Neumann KM 184 mt Cardioid Small-Diaphragm Condenser Microphone – Matte Black

Neumann KM 184 mt Cardioid Small-Diaphragm Condenser Microphone

The Neumann KM 184 mt is a professional small-diaphragm condenser microphone from the renowned Neumann Series 180, finished in a non-reflective matte black coating. Featuring a frequency-independent cardioid polar pattern, the KM 184 mt delivers exceptionally transparent sound reproduction, outstanding transient response, and remarkably low self-noise. Its accurate off-axis performance and high sound pressure level capability have made it a worldwide standard for professional studio recording, live sound, broadcast, and location recording applications. Designed to capture the original acoustic performance without adding coloration, the KM 184 mt is trusted by recording engineers, musicians, broadcasters, and production professionals around the world.

As part of the non-modular Neumann Series 180, the KM 184 mt offers the legendary Neumann sound quality in a compact, cost-effective microphone design. Its transformerless electronics provide a wide dynamic range, excellent common-mode rejection, and exceptionally clean signal transmission, making it suitable for everything from delicate classical performances to high-SPL drum and percussion recordings.

Accurate Cardioid Polar Pattern

The KM 184 mt utilizes a pressure-gradient transducer with a frequency-independent cardioid pickup pattern. Rear rejection remains highly consistent across the frequency spectrum, while the microphone exhibits virtually no off-axis coloration over a wide pickup angle. This ensures natural tonal balance, accurate stereo imaging, and excellent isolation when multiple microphones are used simultaneously.

A gentle presence boost around 9 kHz adds clarity and definition without compromising the microphone's natural character, allowing instruments and acoustic sources to retain their authentic tonal qualities.

Professional Series 180 Performance

The Neumann Series 180 includes three fixed-pattern microphones: the KM 183 (omnidirectional), KM 184 (cardioid), and KM 185 (hypercardioid). Unlike the modular KM A and KM D systems, the Series 180 microphones feature a fixed capsule design, providing outstanding performance with a simplified and economical construction while maintaining Neumann's uncompromising engineering standards.

Transformerless Electronics

The KM 184 mt incorporates Neumann's transformerless output circuitry, delivering exceptional transient response, extended dynamic range, low distortion, and low output impedance. With a maximum SPL of 138 dB and the ability to drive cable lengths of up to 300 meters without significant transmission loss, the microphone performs reliably in demanding studio, broadcast, and live production environments.
