If you have audio jacks that match up, yes. But I'm finding many consumers that never knew what a RCA jack looked like. Some get rather upset as we go over the basics.
I would like to use the Vizio 2.1 sound bar for more than just the TV. Can I also run my receiver through it to play my CD player, Cassette player as well as the FM & AM stations? It seems very limited in it's capacity.
