All-new Analoc2™ connector design. QED Analoc2™ RCA plugs feature high-purity copper signal and ground connections supported by a new non-conductive low eddy current body. The all new Analoc2™ design cleverly substitutes high rigidity thermoplastic material for both the inner support structure and the cable strain relief to eliminate the distorting effects of eddy currents, which are always present in ordinary plugs where bulk brass is used instead.
