In the tradition of the 180 series, the Neumann studio reference
Derived from the famous 180 series alongside the KM 184 and KM 185, the KM 183 embodies the brand's most faithful approach: capturing the acoustic event as it is, without addition or subtraction. Its "diffuse-field" equalization and frequency-independent omnidirectional pattern have made it a worldwide standard for classical music as well as the most energetic drum kits.
Designed for demanding engineers, from orchestra to TV set
Whether recording a grand piano, choir, woodwinds and brass, church organ, or drum kit, this matched pair guarantees a stable stereo image and exemplary tonal consistency. Discreet on camera, the KM 183 also integrates perfectly into TV/radio applications and multi-mic setups where preserving ambiance is paramount.

Questions frequently asked
Neumann KM 183 Stereo Set for classical music and orchestra?
The omnidirectional polar pattern and diffuse field equalization promote homogeneous capture of acoustic sources. The matched pair is designed to maintain a stable stereo image for orchestra, choir, grand piano, or organ.
What power supply is required for the KM 183?
A 48 V ± 4 V P48 phantom power supply is required through the XLR connectors, with a consumption of 3.2 mA per microphone.
Can the KM 183 handle drum recording?
With a maximum SPL of 140 dB at 0.5% total harmonic distortion, these microphones can handle high sound pressure levels. The frequency response covers 20 Hz to 20 kHz. Their omnidirectional pattern allows capturing the drum kit and its acoustic environment.
What is the self-noise level of the KM 183?
The A-weighted equivalent noise level is 13 dB-A, while the A-weighted signal-to-noise ratio reaches 81 dB with a reference of 94 dB SPL. These specifications are suitable for recordings requiring minimal microphone noise contribution.
What accessories are included with the Stereo Set?
The case includes two microphone clips, two windshields, and a wooden box. Each microphone measures 107 mm in length, has a diameter of 22 mm, and weighs 80 g.
