Neumann KMS104 Studio Grade Stage Microphone

The Neumann KMS 104 is a studio-grade vocal microphone for stage use. Its precision-manufactured condenser capsule offers true Neumann sound quality. This is combined with all the virtues of a rugged stage microphone. Specifically, that means excellent pop protection, low handling noise, enormous SPL capability, and high feedback resistance, thanks to its tight cardioid pattern.

Studio Quality For Stage Vocals

The KMS 104 brings studio sound quality to the stage. Unlike usual stage microphones, which use dynamic capsules, the KMS 104 features a true condenser microphone capsule offering the superior clarity that made Neumann studio microphones famous all over the world. At the same time, the KMS 104 possesses the ruggedness required of a stage mic, thus refuting the myth that condenser microphones must be “fragile”.

Unmatched Clarity and Precision

The KMS 104 can stand enormous sound pressure levels of up to 150 dB without clipping, and its tight, frequency-independent cardioid pattern ensures high gain before feedback. The KMS 104 has a much smoother frequency response than dynamic microphones and an airy top-end.

Compared to dynamic microphones, the Neumann KMS 104 has a vastly superior transient response resulting in a more immediate and more emotional vocal sound. In practical terms: effortless intelligibility, without the usual EQ boosts – which further improves feedback resistance.

Optimized for Close Miking and Clear Bass

As a stage microphone, the KMS 104 is optimized for close miking. In fact, a fixed low-cut filter compensates for the proximity effect and ensures clear bass, even if the singer’s lips touch the microphone. The headgrille is made of hardened steel and features a highly effective internal pop screen. It helps to keep moisture away from the capsule.

Reliable Performance with Minimal Interference

Thanks to careful Neumann engineering, these acoustic filters do not cause any sibilance problems. A thick-wall housing protects the head amplifier. Its transformerless output minimizes electromagnetic interference, such as hum. Because of its low output impedance of only 50 ohms, the KMS 104 can drive very long cable runs. It can go up to 300 m (1000 ft) without transmission losses.

KMS 104 Applications

The KMS 104 is primarily a handheld vocal microphone. However, it is suitable for other stage applications as well, due to its high SPL capability and wide dynamic range. Examples include percussion, saxophone, trumpet, trombone, harmonica, acoustic guitar, and guitar cabinets.

Thanks to its superior sound quality, the KMS 104 is also an excellent microphone for home recording and broadcast applications. Because it is optimised for close mic placement, the KMS 104 will pick up a dry sound with very little ambience, which is a big advantage in untreated rooms.
