The Neumann KM 184 Stereoset is a pair of small-diaphragm cardioid condenser microphones made by Neumann. Cardioid pattern, supplied with windscreens and stand mounts.

The KM 184 aims for a faithful reproduction of the source, adding nothing to the original sound and taking nothing away. Its cardioid pattern stays the same at all frequencies, and rejection of sound arriving from the rear (180°) remains very good down into the lows. Across a wide pickup angle the tone does not become coloured, which matters when several microphones are open at once and for precise stereo or surround imaging.

The frequency response is linear, with a slight treble lift around 9 kHz that adds brilliance. The transformerless head amplifier delivers a dynamic range of 125 dB. Self-noise is limited to 13 dB-A and the microphone handles sound pressure levels up to 138 dB. Its low-impedance output stage allows cable runs of up to 300 metres without transmission loss.

The KM 184 belongs to Neumann's Series 180, which has three models: the KM 183 (omnidirectional), the KM 184 (cardioid) and the KM 185 (hypercardioid). These microphones are not modular: the capsule cannot be swapped, unlike the KM A and KM D series from the same manufacturer.

• Uniform cardioid pattern, no off-axis coloration
• Small-diaphragm cardioid capsule
• Neutral Neumann signature
• WNS 100 windscreens + SG 21 bk stand mounts
• Stereo or surround recording with precise imaging
• 48 V phantom power
• Compatible with the PS 15 popscreen and windscreens
• Transformerless electronics, 13 dB-A self-noise

• String ensemble recording with isolation
• Drum overheads and precise instrument recording
• Acoustic instruments: piano, percussion, acoustic guitar, upright bass, violin, cello, woodwinds and brass
• Soloists as well as ensembles, in stereo or surround recording
• Television and radio sets, where its small size keeps it unobtrusive

Can it be used for drum overheads?

Yes. The KM 184 works as well on percussion and drums as on piano, and its excellent off-axis behaviour makes it a strong choice for stereo recording with precise imaging.

What does the set include?

Two KM 184 microphones, two WNS 100 windscreens and two SG 21 bk swivel stand mounts.

What power supply is required?

48 V phantom power (± 4 V). Each microphone draws 3.2 mA and connects through a 3-pin XLR connector.

Is the KM 184 suitable for vocals?

It was not specially optimized for the human voice, but it is often used for classical vocals and whenever authenticity of tone comes first.

How long can the cable run be?

Up to 300 metres (1000 feet) without transmission loss, thanks to the low-impedance output stage (50 Ω).
