In this article, we'll explain how to use your home theater system for a karaoke night.

You can find karaoke machines with factory-installed song libraries, multiple microphone inputs, Bluetooth connectivity, built-in speakers, dedicated lyrics displays, separate volume/equalizer controls, song expansion options, auxiliary inputs, AV outputs, internal batteries, colorful light show projections, compatibility with multiple digital audio formats, included microphones, and more.

The great thing about many of these karaoke machines is that they are plug and play. Those that don’t have a built-in display for lyrics are connected to a television or through a home stereo receiver.

Most karaoke machines support the CD+G format, which is essentially a music CD that displays graphics (lyrics) along with the audio. You can find many of these CDs online (e.g. on Amazon), with the top hits by decade, artist, or music genre. It's the easiest way to expand your karaoke song collection.
