equipments. After being connected to PC, USB interface will directly extract and play
back digital audio signal in a manner similar to the "USB external sound card", to avoid
sound degradation and dynamic range compression caused by digital-to-analog
conversion of PC sound card, and to ensure the restoration of original sound quality.
