“I purchased the 650 soundbar for an older model Samsung TV. I LOVE the sound. I connected using the optical and hdmi cables. Is this necessary? Will this somehow enhance the sound out put or should I only connect using the optical cables. Which is best?”

• Optical works fine (if you run out of HDMI ports) but ARC HDMI lets the devices also control each other to an extent (turning on the TV or soundbar turns both on with HDMI ARC connected, for instance, and same when turning off either). There is no need to use both cables at once. Audio only goes through one at a time.

• Hi Diamond, You will want to only connect one or the other. If your TV has a HDMI input labeled TV ARC then you will want to use just the HDMI cable. This will offer you the best audio and user experience. ~Samsung Solutions
