AudioQuests patented Dielectric Bias System (DBS) puts all of a cables dielectric into a strong stable electrostatic field which saturates (organizes) the molecules of the insulation ... continuously from the time the cable is terminated. The exceptionally simple design uses a wire down the middle of the cable which is simply an extension of a batterys anode. This wire is attached to negative (-) of a DBS battery pack and nothing else. It is not in the signal path and has no interaction with the signal. Depending on the model of interconnect (analog or digital) or speaker cable an existing foil \"shield\" is used as the DBS anode by connecting it to positive (+) of the DBS battery pack. The negative side of a battery is nothing; its just an empty reservoir. Again there is no interaction with signal flow and no extra connections are introduced into the signal path.
