WEL Signature AES/EBUSOLID PERFECT SURFACE SILVER (PSS) CONDUCTORS Solid conductors prevent electrical and magnetic strand interaction. PSS Solid Silver minimizes distortion caused by grain boundaries and maximizes linear RF Noise Dissipation. 72v Dielectric Bias System (DBS) Insulation is also a dielectric that can act like a shunt filter. Biasing minimizes dielectric noise and linearizes the filter, significantly improving wide bandwidth dissipation of induced RF noise.
