This unit plays standard CD+G karaoke discs and takes advantage of the iPod integration with karaoke. You can log on to iTunes, download your favorite karaoke music onto your iPod, then connect your iPod to this unit and sing karaoke. The unit has two microphone jacks, meaning it is ready for both solos and duets. Connect to a TV to see the song lyrics in large format, and entertain an entire room full of family and friends.
