Dielectric-Bias System (US patent 7,126,055)

Greatly improved performance is made possible by a constant 72V charge on the insulation used in WEL Signature products. DBS puts a continuous DC voltage potential (DC bias) between a DBS-only conductor in the cable's center and an outer shield-like conductor. This keeps a cable's insulation fully polarized all the time, something no level of signal can come close to accomplishing.

The result is considerably more transparency and dynamics than possible even from a cable in continuous use, with equipment that is never turned off. Because DBS battery packs are attached when the cables are assembled, they do not require an additional run-in period. Because there is no “load” on the batteries, they will last for years. A test button and LED allow for occasional verification of battery charge.
