Supra Mains Power Distribution Blocks with optional filter, switch, surge protection, DC-blocker & USB-socket

SUPRA Cables offers a mains power product series to further enhance the performance of the consious enthusiast’s audio and/or video gear. The major aim is to protect the mains power from further RFI noise pollution on its way to the devices, to reject the already superimposed audibly detectable noise, protect the devices from possible over-voltage, e.g. close perimeter surge and finally to protect from dc current superimposed on to mains by asymmetric electric appliances. It has been incorporated in one mains block size as an option.
