Supra LoRad MD mains blocks are designed to shield and filter noise and protect the electronic gear from surges and DC (Direct Current) on the mains power.

The NIF-filter (Non-Intrusive Filtering, courtesy of Ben Duncan Research in UK) is a mild RFI filter damping the high frequency noise from all modern household sources.

DC is a result of the increasing number of household appliances that load the AC mains power asymmetrically, introducing a small (0.5 – 3 Volts) but highly malicious DC component.

Our high-end three-way surge protection is designed to shunt high voltage peaks/transients from harming your Hifi gear. Aluminum is a very potent magnetic field insulation. Our mains block as well as adjacent devices is efficiently shielded from both electric, electro-magnetic and magnetic fields, a much wanted property where there is high currents rushing.
