"Furthermore, the KU6300 offers the slightly unique feature of direct-lit LED backlighting technology with LEDS’s across the back of the entire display space"
A:AnswerThere are no analog outputs on this TV so you must get a digital optical audio converter and a digital optical audio cable. Best Buy has these.
A:AnswerYes. It will produce the sound through the soundbar and not the TV plus you can control volume on your soundbar with your TV remote. I have LG soundbar hooked up to it and it works great
A:AnswerThe Samsung specs on the website say it does, but that conflicts with the display info at Best Buy and Samsung's write-up which only hypes that feature in the next model up. I bought one hoping so, but still have not confirmed.
