Question: If I have 3 different sources hooked up to my TV via HDMI (laptop/ps4/xbox one) and run an optical from TV out to sound bar in, it will play all 3?
Document: Maybe the 3.5mm connection is a thing of the past? A key note for any purchaser is that your TV will need an optical audio out to work with this sound-bar (which provides superior sound). And a possible sure-hit winner for many will be the ability to stream music to the device via blue-tooth, which I find myself using more and more.Music and TV sound fantastic through the speakers and the wireless subwoofer worked flawlessly.
The unit arrived on time. I set it up in minutes. I had a 7.1 surround and this time wanted something simple without all the wires to run. One review said that the wireless woofer wouldn't sync-up with the main unit but my unit worked like a &#34;charm&#34;. Plug it in & hook up the optical to my Samsung TV & it was up & running.
At least if there was a passthrough for HDMI, I could get away with my existing input usage. I'm testing this in my bedroom, which is where I moved my Samsung sound bar when I purchased a nice receiver earlier this month and a new surround sound speaker set. That TV only has the input for the Xbox 360 in use, so I'm at least able to use a free HDMI input.
Still, it looks great.Setup was almost painless. It is pretty much a plug and play setup if you already have the required HDMI cable. I recommend theAmazonBasics High-Speed HDMI Cable (9.8 Feet/3.0 Meters) - Supports Ethernet, 3D, and Audio Return [Newest Standard] if you don't. Once plugged in, the system walks the user through a couple of prompts, which takes about two minutes. Unfortunately, the quick start user guide is a little ambiguous.
The directions implied to me that I could connect the sound bar to my TV with either an HDMI cable (not supplied) or the supplied optical cable. In reality, you need BOTH cables. The HDMI cable is required to see the sound bar setup menu on the TV screen.Sound from the sound bar  is much better than my TV speakers (LG smart TV). The apps were redundant for me as I already had the apps through the TV.
But I dont need that because I have a smart tv. I connected it with an optical cable. It only has one hdmi port. I dont even see the point in one. Doesn't there have to be two? So not sure how to connect it via hdmi. I am very happy with the purchase. It is so much easier having a dirrect audio connect instead of a receiver that switches back and forth everytime you change inputs. The sound is better then I expected for the price.
I initially bought the NB3530A instead of this soundbar, but wound up exchanging it for this one because I wanted ARC support, expecting that it would let me run everything off of a single remote. I know that ARC implementations vary pretty wildly in quality, but I figured that since I have an LG TV, this sound bar should work pretty well with it. Big mistake.
The system is great compared to the TV speakers however it is weak at the mid level range. Some voices have a very low volume where as the high and low's are pretty loud and clear. I have a 2010 LG 55&#34; LCD TV. I give the date/spec because my TV has HDMI version 1.3 not 1.4 and works just fine. HOWEVER I need to initiate the simplelink for it to work as my TV does not have ARC support.
I flat out love the LG NB3730A 47" soundbar. I have a big surround system for the TV & music in my living room but the sound built in to the TV in my bedroom, which is where we watch the most, was weak. I tried a cheap RCS soundbar but all it did was make the sound louder, not better. When I hooked this one up the improvement was drastic. The dialogue clear & the loud sounds appeared whenever thwy were appropriate.
(There is a set-up DVD included, but it didn't seem worth the time to use it.) The optical cable is included, but the HDMI cable is not. The internet connection was quick and easy. The power cable input into the sound bar is very loose; once it's in place it won't fall out, but it did several times during set up.The sub-woofer does not need to be connected and can be placed anywhere in the room.
Answer: Yes is should work out fine.... I had my Roku hooked up to HDMI 1 then I had my xbox hooked up on HDMI 2 ( also used as my DVD player ) and then just had the normal antenna hooked up for free TV over the air via coax and I run everything from my optical out to the soundbar, so no matter what input your on the optical should play all...  Hope this helps.
