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.
