You are bidding here on a combination of DC and mains filters. The board combines both filters.
Since many customers have reported a sometimes drastic improvement in sound after using a single DC filter, both filters are now available together as a combination on one board.
You can find more information on how the filters work on my website (https://www.audio-perfect.de/netzfilter.html). There you can also download installation instructions.
The board is fully assembled and measures 100x67mm. The height is about 45mm. The filter can be loaded with a power of up to 500VA.
The DC filter can be switched off by connecting an additional switch. Simple connection by screw terminals. A separate protective conductor connection is provided for the enclosure. This can also be made via one of the mounting holes.
By bidding, you accept that I am selling as a private individual and therefore do not provide a warranty under EU directives.
