A:AnswerMy suggestion would be to use the digital visual audio output into your receiver/amplifier that powers your speakers. You would then have 2 equalizers to use to adjust the sound as you want it. One on the TV and one on your amplifier. I did it that way with my old TV and it worked just fine. Good luck.
A:AnswerIf you are on Best Buy they have a tremendous listing of specifications for all their TV's, including the items they have and items they work with. If not, their techs will find the information for you.
A:AnswerYes. I have the 65" Samsung with a Samsung soundbar/subwoofer. I have connected via USB port and can also use it with eARC connection if I want. Right now I don't need the USB port it's in (ARC) and the sound blows me out of my familyroom!! GREAT SOUNDBAR AND TV!!
