Neumann KM 184 MT Octo Set

Neumann KM 184 MT Octo Set — a professional eight-microphone bundle including matched KM 184 MT small-diaphragm cardioid condensers. Each microphone delivers transparent, natural sound with precise off-axis behavior and outstanding consistency across all units, making the set ideal for orchestral, ensemble, and surround recordings. The KM 184’s frequency-independent cardioid polar pattern ensures excellent rear rejection even at low frequencies, while the transformerless output stage provides a clean signal and a wide dynamic range of 125 dB.

Designed for engineers who demand absolute tonal accuracy, the KM 184 MT Octo Set offers true sonic uniformity, allowing multi-mic configurations to capture detailed stereo and multichannel imaging without coloration. Each microphone maintains a smooth linear frequency response with a gentle lift around 9 kHz for added brilliance. With a self-noise level of just 13 dB-A and the ability to handle SPLs up to 138 dB, the KM 184 performs flawlessly on acoustic instruments, percussion, and full orchestras. The matte-black “MT” finish ensures a discreet appearance in studio and stage environments.
