Making a homemade RCA to USB cable is possible but, while the wiring of RCA jacks to the cable is easy, the same isn't true of wiring a USB connector. USB connectors are intricate: The size of the unit and wires doesn't help. You ideally need to have specialist tools so, unless you intend to produce many RCA to USB cables, it's cheaper and simpler to convert RCA to USB with a converter unit.

Insert the USB connector into your converter device. It can only fit one way.
Insert the red RCA jack attached to your RCA cable into the red RCA socket. Repeat the process for with the black (sometimes white) RCA jack and the yellow RCA jack.
Connect the other end of your RCA cable to the corresponding sockets on your device. Turn on both devices and your RCA signals will be converted to USB by the converter unit.
Tips and warnings
- Visit your electrical store or go online to purchase a RCA to USB converter unit. They vary in price starting from £13 to £19, as of 2010. The more expensive converters purport to provide better signal conversion. The converter is a small unit that has three RCA sockets on one end, then a USB cable leads from the other end of the unit to a USB connector.
