Question: I see it has 3 HDMI so do I hook up my cable and PS3 directly to the unit? Then connect HDMI out to TV?
Document: I have been using this sound bar for few days now. It works well with my Panasonic TV ST60. Works well with my phone and tablet via bluetooth. It has 3 HDMI inputs which is good enough for me (Cable box, Mac mini, and PS3). It has ARC hdmi port compatible (one hdmi connection for TV sounds to sounds bar). 3D passthorough.Decent sound. I don't expect audiophile sound with this sound bar. 1. it is a sound bar.
Really? Look at the pages and pages of tiny words. Really? Who is going to read that? Even if I did, I have no idea what it means. I still don't know what ARC is. The point is, not everyone is electronics savvy. Pictures. 1-2-3 instructions. Put this cable here. Plug this in there. SIMPLIFY.Normal Non-tech Humans, try this:1. Plug in sub woofer2. Connect HDMI cable to TV.
If that doesn't work, try another one. Don't sweat it.3. Connect HDMI to the soundbar. Again. Try a slot. Try another slot. Don't beat yourself up over it.4. Connect the other thin cable (whatever it is) in to the TV. Same as above. There was only one place to put this on my tv.5. Connect the thin cable to the soundbar. There is only one place. Yay.6.
Very satisfied with this sound bar. I've purchased sound bars in the past - I particularly like the added bass so I was interested in a unit with a separate subwoofer. This unit fit the bill - a reasonable price and great sound. Hook up was straightforward - for my set up I used the enclosed optical cable from my TV to the unit - plugged it in and plugged the subwoofer in and was good to go. I'd also point out that the Bluetooth was an added bonus for me.
Just got this system today. Setup was a breeze with Sony Bravia TV. The ARC HDMI port made connecting the sound bar simple. Having the cable box, PS3, and Apple TV connected makes navigating the inputs a snap with Bravia Sync. Watched 300: Rise of an Empire in 3D and images and sound synced perfectly. The crystal clear dialogue and incredibly deep bass made it feel like I was at the cinema. Wish I hadn't waited so long to buy this.
This sound bar was mounted under a 52&#34; Sony Bravia TV [with brackets I bought] and was supposed to be hooked up via HDMI cables to the TV and a Sony BD player. According to the directions the TV & BD player sound have been run through the sound bar and then controlled with the 1 remote. [I also tried to hook up a Apple TV and Comcast cable box]After MANY efforts to have it sync with the TV, BD etc.
I connected it to my TV with the provided optic cable but may change to the HDMI instead to see if it gets even better sound. We have a large sofa sectional with a small void behind the corner piece and have hardwood flooring. I placed the wireless subwoofer in this area. WOW! I love this whole system. I've played my iPhone music using the Bluetooth and it sounds amazing and PLENTY loud for me.
Reading the great reviews just had to see it for myself. Wow, the sound is great, so much better than the surround sound we were using. Easy set up (have a long HDMI cord for hook up-does not come with one). Bluetooth was easy to set up as well. We have a medium size room in which we watch tv, the sound is perfect. I think if the room was larger, taller ceiling, it would not sound as well.
I am using this unit with my Sony Bravia TV. The interface was easy with an HDMI cable, not included. They do provide an optical cable, but the HDMI allows control of all our Sony units automatically. All units switch to the correct input when the device is turned on. The TV checks and switches to these external speakers automatically and changes to the correct sound field based on the subject matter of the show. ie: Movies, Music, Voice, etc.
Great space saver. This bar will replace your tuner and has 4 HDMI inputs which will elimate all the excess cable needed to connect your cable box, DVD player and TV. The wireless sub-woofer can be place anywhere in the room near an AC outlet. The Soynd BAr had Bluetooth capability which means you can play your music from you iPhone or iPad through the system. It is easy to install and locate.
Answer: Cable box goes directly to TV. The optical plug goes from sound bar to cable box.  HDMI cable from game unit to bar. We used HDMI 1 for GAME UNIT.  Then HDMI output on bar goes to TV.  There may be an easier way but this works well.
