PowerLine Plus carries a number of features to lift performance still further. Mains earth has a finite impedance and does behave as an antenna, perfect for capturing RF energy. The PowerLine Plus earth line choke is custom made with a special high permeability core. This gives massive attenuation of any RF noise in the system earth bus and signal ground. The input connector is a rhodium plated IEC by Oyaide. Finally, a single pole shunt filter is fitted. This topology allows direct connection of the live and neutral conductors to the load, providing effective noise attenuation without any impact on peak current delivery.
