Reviews : If your TV doesn’t support Audio Return Channel on HDMI, you won’t be happy. If it does, you may find that only one HDMI port on your TV supports it and that is the one to use. If you must use Wifi instead of Ethernet cable, you’ll need an adapter because it doesn’t have it built-in. When connecting the wires to the speakers, make sure that the black wires connect to the black sockets. If the wires are reversed, sound will come out, but the system won’t sound the way it should. Also make sure that you don’t push the insulated part of the wire into the socket. After locking in the wire, pull on it gently to make sure it’s secure. The other end of each speaker wire must be pushed into the receiver until it snaps in. Power up the receiver, go to the settings and do the firmware update. When that is done, go through every option on the settings menu. In the audio section you will find settings to specify the distance between the place where you sit and each speaker. After you set all the distances, run the test to make sure that each speaker is properly connected. If this sounds too difficult for you, ask the person who helps you with your computer problems to do it for you. After that, try reading the manual so you know how to use it. Virtually all of the poor reviews are due to incorrect setup (wiring and settings), not upgrading the firmware, and/or not reading the setup instructions and user manual. I left off one star because it was really stupid to leave out the WiFi. But they probably left that out because it’s just another thing for users to get wrong. NOTES: Ethernet cable must be CAT 5e or higher. HDMI cable must support 1.4a. Don’t expect to watch Netflix over DSL, or if your router is old. And have you updated your router firmware lately? Pleasantly surprised with this system. The speakers were smaller than my previous system, but in this day and age, size isn’t a deal breaker. Bose saw to that. My old system had a sound bar for the center speaker, this one has a small speaker just like the R/L surrounds. Sound quality was great for suck a small system. The player was half the size of my previous one, but that was actually a bonus and left more shelf space.The remote has a bit of a learning curve to it. Buttons not where I expected them. But overall functional. Was great the 1st month. When I watch DVDS there is no audible verbage from the actors so I have to read subtitles. All the background noise and mistake inserts and voice over are there, which is interesting but, this is unacceptable. Surround only works with the latest greatest surround DVDs. If it wasn’t recorded that way, you won’t hear it that way. Most of my collection is older sooooooo you know. I wish I could hook it up to my stereo but it has its own unique inputs. 😕. When it is working in all its glory it’s great .
