The Neumann KMS 104 BK offers a wide frequency response from 20 to 20,000 Hz, ensuring faithful reproduction of vocals from low fundamentals to crisp high harmonics. Its cardioid polar pattern delivers focused pickup on the singer while reducing stage bleed and feedback.

Built as a wired XLR-3 microphone, the KMS 104 BK requires 48 V phantom power and draws just 3.5 mA, making it compatible with standard stage mixing consoles and microphone preamps. The microphone’s input impedance is 50 Ω with a recommended load impedance of 1000 Ω for optimal performance.

The supplied pop-filter helps control plosives and improves intelligibility on close vocal work.

Physically, the microphone is rugged and stage-ready: it measures 180 mm in height, has a diameter of 4.8 cm, and weighs 300 g. The matte black finish gives a professional, unobtrusive look on stage, and a single unit is included per package.

Typical use cases for the Neumann KMS 104 BK include lead and backing vocals in concerts, musical theater, broadcast applications on stage, and any live-sound situation where pristine vocal reproduction is required. Its cardioid pattern and robust build make it suitable for loud stage environments and monitor-heavy setups.
