For best results, when using the CO2 RCA jacks, use a
good-quality S/PDIF cable. The cable should be coaxial with 75-
ohm impedance. Vendors sell cables specifically for this use, but a
good-quality video dubbing cable also has the proper characteristics.
Asi es que por eso compre un cable de video de muy buena calidad pero no funciona, alguna idea?
