Connection Principle: Our USB to 2 RCA Adapter is for connecting and transfering (not converting, transfer signals not data) signals from USB port to Red and White RCA ports, which plays the role as signal transmitter NOT signal converter. The Red rca stands for right audio chanel, White rca for left audio chanel. It is a one-way cable from USB A to RCA meaning it CAN NOT support from RCA to USB-A.4. High Quality Cable: USB to RCA Audio Adapter with high-fidelity structure design, adopts premium OFC (Oxygen-Free Copper) to enhanced signal clarity, effective EMI and RFI rejection and flexibility. Tips: USB carries digital signals and RCA carries analog signals, in order for them to communicate so both the input and output devices need to support signal conversion functions (encoding and decoding) otherwise it will not work!5.
