What are those 3 red,yellow and white things on the back of a karaoke machine?

Question

I'm trying to find out what you can use those for..they look like video game inserts.

Answer 1

if they are circular then they are for your video, audio and ... im not sure what the other is for, but you can plug all three into your TV so you can use the karaoke machine.

Answer 2

Red, white, and yellow plugs are for video and audio.  It's probably so you can hook up the karaoke machine to a TV and/or speakers.

Yellow = composite video

White = left audio channel

Red = right audio channel
