• THE SOUNDBAR COMES WITH AN OPTICAL CABLE THAT YOU CAN USE BETWEEN THE TV AND THE SOUNDBAR. OPTICAL CABLE OR TOSLINK IS THE BEST CONNECTION FOR AUDIO. FOR VIDEO, THE BEST IS HDMI, IT ALSO CONNECTS THE AUDIO SIGNAL THOUGH. USE HDMI CABLES TO CONNECT AMAZON TV BOX, 4K BLURAY PLAYER, OR PLAYSTATION. HDMI COMES IN DIFFERENT FLAVORS, SOME ARE CLAIMED TO BE "FASTER" AND EXPENSIVE BUT I DOUBT IF YOU CAN EVER TELL ANY DIFFERENCE.
