Neumann KM 185 mt Stereo Set Hypercardioid Small-Diaphragm Condenser Microphones – Matte Black

Neumann KM 185 mt Stereo Set Hypercardioid Small-Diaphragm Condenser Microphones

The Neumann KM 185 mt Stereo Set is a factory-matched pair of professional small-diaphragm condenser microphones from the renowned Neumann Series 180. Finished in a discreet matte black (mt) coating, each microphone features a frequency-independent hypercardioid polar pattern that provides exceptional isolation, natural sound reproduction, and outstanding off-axis consistency. Designed for professional studio recording, broadcast, live sound, classical music, and location recording, the KM 185 mt Stereo Set delivers precise stereo imaging and the legendary sonic accuracy that has made Neumann microphones an industry standard.

The matched microphone pair is carefully selected to provide consistent sensitivity and frequency response, making it ideal for stereo recording techniques that require excellent phase coherence and accurate localization. As part of the fixed-capsule Series 180, the KM 185 mt Stereo Set offers world-class Neumann performance in a compact, rugged, and cost-effective design.

Precise Hypercardioid Directionality

Each KM 185 mt utilizes a pressure-gradient transducer with a frequency-independent hypercardioid pickup pattern. Its highly directional design effectively attenuates off-axis sound while maintaining a natural tonal balance, making it an excellent choice for recording in acoustically challenging environments or multi-microphone setups. Whether capturing orchestras, drum overheads, acoustic instruments, or live performances, the microphones provide outstanding source separation with minimal coloration.

Factory-Matched Stereo Pair

The KM 185 mt Stereo Set is optimized for professional stereo recording techniques including ORTF, X/Y, NOS, and other coincident or near-coincident microphone configurations. The matched pair delivers accurate stereo imaging, stable phase response, and realistic spatial reproduction, making it ideal for immersive audio, orchestral recording, ensemble performances, and broadcast production.

Transformerless Neumann Electronics

Each microphone incorporates Neumann's transformerless output circuitry, providing exceptional transient response, low distortion, a wide dynamic range, and reliable low-impedance signal transmission. With a maximum SPL of 142 dB and low self-noise of just 15 dB-A, the KM 185 mt Stereo Set captures everything from delicate acoustic performances to high-level percussion with remarkable clarity and precision.
