Neumann KM 184 MT Small Diaphragm Condenser Microphone

The Neumann KM 184 MT Small Diaphragm Condenser Microphone is a state-of-the-art small diaphragm condenser microphone with a uniform, frequency-independent cardioid polar pattern. Its very natural, transparent sound with very low self-noise and high SPL capability have made the KM 184 a worldwide stage and studio standard for many applications ranging from classical piano to heavy metal drums.

FAITHFUL

While many microphones, these days, are designed to add some sonic imprint of their own, there are many applications that require a faithful reproduction of the original acoustic event, without adding or removing anything. That’s where the Neumann Series 180 comes in.

The Neumann Series 180 consists of three members with different pickup patterns: KM 183 (omni), KM 184 (cardioid), and KM 185 (hypercardioid), thus covering the majority of stage and studio applications. Because the Series 180 microphones are non-modular, they are more cost-effective than the modular Series KM A and KM D (which offer a wide range of interchangeable capsule heads for analog and digital output stages).

CARDIOID

Despite its attractive pricing, the KM 184 offers state-of-the-art Neumann engineering. Its cardioid pattern is frequency-independent; rejection of rearward sound (180°) is excellent, even at low frequencies. In practical usage, there is no sound coloration over a wide pickup angle, which is crucial in multi-microphone setups and for precise stereo/surround imaging. The KM 184’s frequency response is very smooth and linear with a slight treble lift around 9 kHz for added brilliance. Its innovative transformerless head amplifier offers a wide dynamic range of 125 dB and is carefully designed to maintain the capsule’s sonic integrity. The KM 184 has a very low self-noise of only 13 dB-A and can handle high sound pressure levels of up to 138 dB free from distortion. Due to its low impedance output stage, the KM 184 can drive long cable runs of up to 300 meters (1000 feet) without transmission losses.
