Neumann KMS
104/KMS 104 plus/KMS 105 Vocal Microphones |
|
Product Code: KMS104//KMS105
|
The KMS 104/104 plus and the KMS
105 microphones have been developed to optimally transmit the human voice with
respect to the demanding conditions present on the live stage.
The KMS series has become the internationally acknowledged standard for
first-class stage microphones.
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.
Especially due to their low self-noise and crosstalk behavior which is free of
coloration, the KMS microphones are ideal for use with in-ear monitoring
systems.
The KMS 104 and the KMS 104 plus have a condenser microphone capsule with a
cardioid directional characteristic which provides the best possible suppression
of sounds originating from behind the microphone. In contrast, with its
supercardioid characteristic the KMS 105 is particularly good at suppressing
sounds originating from the entire 180� hemisphere behind the microphone. The
KMS 104 plus features, compared to KMS 104, a more extended bass frequency
response. In close cooperation with professional musicians, with the aid of
extensive practical tests, the KMS 104 plus has been especially optimized for
the requirements of female voices in the rock and pop field.
The user can thus select the version that is optimally suited to the specific
application.
Acoustic features
The studio condenser capsules used in the microphone versions 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.
In KMS microphones, carefully adjusted acoustic filters and transformerless
impedance converters that can handle very high sound pressure levels prevent the
microphones 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 above-mentioned 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 KMS 104/104 plus and KMS 105 vocal microphones when they are used with a
stage sound system.
Electrical features
Since vocal microphones are typically addressed at close range, for the bass
frequency response of the microphones, electronic compensation is used for the
proximity effect in the respective capsules.
In addition, the microphone has an invariable, built-in high-pass filter with a
cutoff frequency of 120 Hz (�3 dB, measured in a free sound field). The dynamic
range of the KMS microphones is 132 dB, and the maximum sound pressure level is
150 dB.
The low self-noise level of only 18 dB A permits the 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.
Mechanical features
Microphones designed for use on stage require a particularly robust
construction. The KMS 104/104 plus and KMS 105 therefore have thick-walled metal
housings, which also provide effective protection against handling noise.
The microphone headgrilles are made of hardened steel. If required, they can
easily be unscrewed to permit cleaning of the interior acoustic filters.
Delivery Range
The KMS 104/104 plus and KMS 105 microphones, with a matching stand clamp, are
supplied in an attractive padded nylon bag that is sufficiently durable for
touring.. |
