A:AnswerHi, the interface that is being used is the included Audio Optical out cable as well as an HDMI input cable/out sold separately. Once connected, you can configure the audio source on the tv by going to the audio settings on the TV menu options. I have a 2017 LG smart TV and it picked it up just fine. I'm sure new iterations of LG TVs would do it automatically. Again, the cable is included in the box to connect the sound bar to the TV.
A:AnswerDaphane, why do you call the SP7Y soundbar passive? It has to be plugged in to 110v electric wall socket to power its built in amplifier, which makes it active.
A:AnswerI haven’t purchased them but yes you can. LG makes a wireless receiver that needs to be plugged into ac outlet and two speakers are connected to that.
A:Answerthis is an excellent sound bar for the price, the only thing is it doesn't have rear speaker . but this is just what i wanted more power in center left and right speakers and sub is awesome.....

A:AnswerI'm 80 yrs old and don't know "Jack" about this sound bar other than it does a pretty decent job but doesn't provide me the 'surround sound' I was seeking to get.
A:AnswerI really don’t know, but you don’t need 2 , as this system works great with the bass speaker it comes with. Too much bass will make the sound muffled and vibrate everything in the room. Also any dialogue or lyrics will be very difficult to understand.
