Operating instructions
CV042 Isolator/noise filter
Item no. 1429552
Intended use
The product is intended for reducing noise when using high-end music equipment. The RCA
audio ports of the noise filter are gold-plated. When having installed music equipment, guided
cables can cause undesired background noise (hissing and humming noise) during music
playback. The product eliminates such background noise. Hissing noise is usually caused for
music equipment in vehicles, which is why noise filters are often used in such environments.
It is intended for indoor use only. Do not use it outdoors.
