The Neumann KMS 104 microphone was developed to transmit the human voice optimally whilst taking into account the demanding conditions present on stage. The KMS series has become the international reference for high-end stage microphones.

The high acoustic resolution and uniform frequency response of the microphones ensure that the musician maintains optimal control of their stage performance at all times.

Thanks in particular to their low self-noise and their uncoloured off-axis behaviour, KMS microphones are ideal for use with in-ear monitoring systems.

The KMS 104 and KMS 104 plus are equipped with a condenser capsule with a cardioid directional pattern that provides the best possible rejection of sounds coming from behind the microphone. The KMS 104 plus offers, compared to the KMS 104, an extended frequency response in the low frequencies. In close collaboration with professional musicians, through numerous practical tests, the KMS 104 plus has been specifically optimised for the needs of female voices in rock and pop.

Users can thus select the version best suited to the specific application.

ACOUSTIC CHARACTERISTICS

The studio condenser capsules used in the microphone versions form the basis for transmitting all the nuances of the human voice. Compared to other handheld microphones, which operate primarily with dynamic capsules, the KMS series offers particularly high acoustic transparency, a wide frequency range and fine transient resolution.

In KMS microphones, carefully tuned acoustic filters and transformerless impedance converters capable of handling very high sound pressure levels prevent the microphones from being overloaded even by powerful plosive sounds.

Despite excellent protection against plosives, sibilants and "S" sounds are transmitted with their natural accentuation, as only condenser microphones allow. Furthermore, the acoustic filters mentioned above are designed to preserve the distinctive directional characteristics of the capsules even at low frequencies. The filters thus ensure a very high level of feedback protection for the KMS 104|104 plus and KMS 105 vocal microphones when used with a stage PA system.

ELECTRICAL CHARACTERISTICS

Since vocal microphones are generally used at close range, electronic compensation is used for the proximity effect in the respective capsules for the frequency response of the microphones.

Furthermore, the microphone features a fixed integrated high-pass filter with a cut-off frequency of 120 Hz (-3 dB, measured in free field). The maximum sound pressure level of KMS microphones is 150 dB.

The low self-noise level of only 18 dB A allows the microphones to be used at high gain levels without risk of additional noise. Even at long distances, the microphones thus operate with a high signal|to-noise ratio, facilitating the freedom of movement and creativity that are important for the performer.

Thanks to the transformerless output circuit, the microphone signals can be transmitted even over long cables without any loss of sound.

MECHANICAL CHARACTERISTICS

Microphones designed for stage use require a particularly robust construction. The KMS 104|104 plus and KMS 105 are therefore equipped with thick-walled metal bodies, which also offer effective protection against handling noise.

The microphone grilles are made of hardened steel. If necessary, they can be easily unscrewed to allow cleaning of the internal acoustic filters.

BOX CONTENTS

The KMS 104|104 plus and KMS 105 microphones, with an appropriate mounting clip, are supplied in an elegant padded nylon pouch robust enough for touring.
