Sub-3 uses three solid 6.1% Silver-Plated Long-Grain Copper conductors inside PE Air-Tubes. Solid conductors eliminate strand-interaction distortion. PE Air-Tubes minimize signal smearing caused by any solid or foam insulation. The 72V Dielectric-Bias System (DBS) almost eliminates remaining insulation-induced distortion. Three conductors ensure optimum-performance RCA plugs or XLR plugs. A 100% coverage shield ensures noise-free performance.
