Audio signals are generally sent between devices through RCA audio cables. For example, RCA audio cables can connect the RCA ports on DVD players and televisions, so the audio from the DVD player can be heard through the television speakers. While there are testers available that can validate the activity of RCA cables, easily test a cable by connecting it to the proper devices and performing a few simple steps.
Instructions
1. Connect the red and white RCA audio cables to the red and white ports on the back of your audio device.
2. Connect the other end of the audio cables to the ports on your television. Turn your television on and change the channel to its RCA input channel. You should be able to hear the audio signal on your television speakers.
3. Remove the white cable from its RCA port on the back of your television. You should now only hear audio coming out of the television's right speaker.
4. Replace the white cable and remove the red cable from its RCA port on the back of your television. You should now only hear audio coming out of the television's left speaker.
