Mains filters

infoOur mains filters use earth as a reference therfore to maximise performance the socket or extension they are plugged into should be earthed (‘grounded’).

 

Sercal Electronics offers a range of filters to suppress mains-borne noise and high voltage transients and surges.

Plug our mains filters in next to your system and it will create a "noise free" area around it. You will hear more detail and see better pictures. Use more filters and the benefits will accumulate with the mains becoming cleaner still.
