Neumann KMS105-NI

The KMS 105 microphones have been developed to permit optimal transmission of the human voice, and are thus microphones of choice for demanding live applications. Due to their low self-noise and crosstalk behavior which is free of coloration, these microphones are ideal for use with in-ear monitoring systems.

With its supercardioid charecteristic the KMS 105 is particularly good at suppressing sounds originating from the entire 180° hemisphere behind the microphone. The high acoustic resolution and smooth frequency response of the microphones ensure that the musician has optimal control of the stage performance at all times.

The studio condenser capsules used provide the basis for transmitting all the nuances of the human voice. In comparison with other handheld microphones, which operate mostly with dynamic capsules, the KMS series has a particularly high acoustic transparency, a wide frequency range and a fine resolution of transients. Carefully adjusted acoustic filters and transformerless impedance converters that can handle very high sound pressure levels prevent the microphone from being overloaded even by strong plosive sounds. In spite of excellent pop protection, sibilants and "S" sounds are transmitted with their natural accentuation, as is possible only with condenser microphones. Furthermore, the acoustic filters are designed so that the distinctive directional characteristics of the capsules are preserved even in the bass range. The filters thus ensure a very high level of feedback protection for the microphone when used with a stage sound system.

Since vocalist microphones are typically addressed at close range, for the bass frequency response of the microphone, electronic compensationis used for the proximity effect in the respective capsules. In addition, each microphone has an invariable, built-in high-pass filter with a cutoff frequency of 120Hz (-3dB, measured in a free sound field). The dynamic range is 132dB and the maximum SPL is 150dB. The low self-noise level of only 18 dB-A permits both microphones to be used at high gain levels without the risk of additional noise. Even at large distances, the microphones thus operate with a high signal-to-noise ratio, facilitating the freedom of movement and creativity that are important to the artist. Due to the transformerless output circuit, the microphone signals can be transmitted even through long cables without loss of sound.

Microphones designed for use on stage require a particularly robust construction. The KMS 105 therefore has a thick-walled metal housing, which also provides effective protection against handling noise. The microphone headgrilles are made of hardened steel. If required, they can easily by unscrewed to permit cleaning of the interior acoustic filters.
