Electra™ Shielded Mini Power Conditioning Cord uses a new conductor geometry to provide superior shielding and isolation from external interference. This advanced design extends the functions and benefits of power conditioning all the way to the component’s power inlet. With the world’s purest OCC-7N copper conductors, Electra provides the ultimate performance from streamers, wireless speakers, TVs and soundbars. Since they function as filters, longer lengths improve performance.
