You can improve the sound of your Westinghouse television by adding external speakers. Be advised: You'll need a special type of speaker to do the job. Westinghouse TVs, like all televisions, don't have powered speaker outputs. They output a preamp-level signal. This means you'll need a set of powered speakers, like those you use for a computer. Connection is simple and only requires a readily available adapter cable.
Put the RCA plug on the adapter cable into the "Audio Out" jacks on the back of the television. Plug the white plug into the white jack; the red plug into the red jack.
Connect the jack on your powered speakers' audio input cable into the other end of the adapter cable.
Video of the Day
Place one speaker on either side of the television. Point the speakers to where the television viewers will be sitting.
Plug the power cable of the speakers into a wall outlet or power strip. Turn on the speakers' power when you want to use them.
