Stage microphone Neumann KMS 104 bk — wired cardioid performance mic, XLR-3, 20–20000 Hz, 4.5 mV/Pa, 300 g, black

The Neumann KMS 104 bk is a studio-grade stage microphone that brings Neumann condenser sound quality to live performance. It uses a precision-manufactured condenser capsule for clear, detailed vocals while offering the durability and handling characteristics required for stage use. The microphone delivers a frequency response of 20–20,000 Hz, low output impedance (50 Ω) for long cable runs, and is built to withstand very high sound pressure levels up to 150 dB without clipping.

Advantages

The KMS 104 combines the clarity and transient response of a true condenser capsule with rugged mechanical design suitable for handheld stage use. Its tight, frequency-independent cardioid polar pattern provides excellent feedback rejection and consistent off-axis behaviour. Built-in acoustic pop protection and a hardened steel headgrille protect the capsule and reduce handling noise. A fixed low-cut characteristic compensates proximity effect for clear bass at close distance, and the transformerless output helps minimize electromagnetic interference.

Suitable for

• Live vocal performances (handheld)
• Close-miked instruments on stage: acoustic guitar, guitar cabinets
• Brass and woodwind: trumpet, trombone, saxophone
• Percussion and harmonica
• Home recording and broadcast where a dry, close sound is required

How to use

Use the KMS 104 as a handheld vocal microphone at close distance to take advantage of its optimized close-miking characteristics. Connect the microphone to a mixer or preamp via an XLR-3 cable and supply 48 V phantom power. Position the mic with the capsule facing the sound source; the tight cardioid pattern requires reasonable aim toward the performer to maximize gain before feedback. For instruments, place the microphone close to the sound source to capture a dry, direct sound with minimal room ambience.

Usage recommendations

The microphone's built-in pop screen and hardened grille reduce moisture and plosives, but avoid direct contact of the capsule with liquids and handle the microphone by its body. For long cable runs up to 300 m, use balanced XLR cable to maintain signal integrity. If additional low-frequency control is needed, use the mixing console's high-pass filter rather than placing the mic further from the source.
