Neumann KM 185-NI Hypercardioid Small-Diaphragm Condenser Microphone Nickel

Neumann KM 185-NI: Hypercardioid Isolation in a Series 180 Pencil

The Neumann KM 185-NI is a hypercardioid small-diaphragm condenser microphone, a single Series 180 pencil mic in a nickel finish built for tight directional pickup. Its defining trait is a hypercardioid pattern with maximum rejection around 120 degrees off-axis, the tightest capture in the Series 180 family. Where the omni KM 183 hears the whole room and the cardioid KM 184 leans forward, the KM 185 clamps down on a single source and pushes spill from the sides and rear out of the picture. A transformerless output and 50-ohm impedance let it drive long cable runs into any 48 V phantom input. That combination makes it the isolation specialist of the line.

Behind the Nickel Body

A small-diaphragm hypercardioid capsule sits at the tip of the slim 4.2-inch body, feeding a transformerless output stage directly. The nickel finish is the classic studio look, and the compact form fits into the cramped spots that close-miking demands. Sensitivity is 10 mV/Pa into 50 ohms, so the mic hands the preamp a strong signal and keeps added gain low. There is no transformer in the path to smear transients, which is part of why percussion sounds so immediate through it. This is Neumann engineering scaled down to a pencil.

Natural Sound Off the Beaten Path

The hardest test of a directional mic is how it treats sound that arrives from the wrong angle, and the KM 185 keeps that off-axis energy tonally natural instead of hollow. Its directivity stays consistent across the frequency range rather than collapsing in the treble, so a hi-hat bleeding into a snare mic still sounds like a hi-hat. That behavior keeps close-miked kits and ensembles from developing the phasey, boxy leakage that plagues lesser directional mics. It is a quiet quality that only reveals itself in the full mix. Engineers who chase clean isolation come to rely on it.

Loud Sources, Low Noise

With a maximum SPL of 142 dB at 0.5% THD, the KM 185 sits right on a snare rim or in front of a brass bell without distorting. A-weighted self-noise of 15 dB-A keeps the floor low enough for quiet acoustic detail. Between those points lies a 127 dB dynamic range that suits both a delicate mandolin and a cracking snare. The mic draws 3.2 mA from standard 48 V phantom power. One pencil covers a wide swath of the studio's needs.

Built for the Spill-Heavy Session

Close-miking a snare and toms is the KM 185's signature job, where its rear rejection keeps cymbals and neighboring drums out of the channel. On a loud stage it isolates an instrument from the wash of monitors and other players. In an ensemble with high spill, it lets one voice or instrument stand apart. Theater and television sound crews use it where a source needs to be pinned down in a busy acoustic. Anywhere a cardioid leaks too much, the hypercardioid pattern earns its place.

In the Box and Who Should Buy It

Each KM 185-NI ships with a WNS 100 foam windscreen and an SG 21 bk stand-mount swivel in the nickel finish. It suits the engineer who already trusts the Series 180 sound but needs more rejection than the cardioid KM 184 provides. Drummers, live-sound engineers, and ensemble recordists are its natural buyers. Pair two of them for stereo, or add one to a locker that already holds omnis and cardioids. It is the directional tool in a small-diaphragm system that studios have relied on for decades.
