Plug the RCA side of your cable into the jacks labeled "RCA Output", matching the colors.
Look at the side of your recording device. It will have an 1/8-inch input jack. This may have the icon of a microphone next to it. The icon is standard on both tape recorders as well as computers.
Plug the 1/8-inch end of your cable into the microphone input on your recording device.
