A:Answer I don't think so. I'm using an OPTICAL digital cable from the TV to the soundbar, and it is nicely synchronized- so I suggest that. MCM Electronics does sell a box that converts S/PDIF optical to COAX digital and vice-versa if you really need to go that route. You could also use the RCA audio jacks, but I haven't tried them yet, or the mini stereo headphone jack.
