A USB cable has a mixture of a signal line that transmits digital signals within a single cable and a power line that supplies bus power. The mixture of signal lines and power lines is affected by magnetic and electric fields generated by each other, resulting in significant quality degradation. The biggest drawback of USB cables that pursue convenience only is this cable structure, and no matter how high-performance conductors, insulation, or shields are applied, mutual interference between the signal line and the power line is inevitable, and excellent transmission characteristics and sound quality can not be obtained. The R-AU1-SP/R-AU1-PL features an innovative construction with an ACOUSTIC REVIVE utility model that completely separates the signal line from the power supply line. The structure using a cable with a dedicated two-core shield structure for each signal line and power supply line realizes high-quality sound quality without mutual interference and transmission degradation.
