Logitech smart remote. You can connect up to 8 items and set up so it you push music what ever speakers you assign will come on, or watch a movie and the TV switches HDMI, turns on DVD and correct speakers… very handy once you get it set up (do on computer and sync to remote) Can also use you phone as a remote. I liked to so much that I bought 2, this purchase if for 2 complete set ups.
