Question: Are the speakers wirelessly connected to the reciever?
Document: You will get a high pitch from the TV speakers if it isn't. The pass-through is nice. Late at night you can just use the TV speakers instead of the reciever.Plenty of options with this system. Give it a little time to get it tweeked to how you want it. The Audyssey 2EQ self set-up of the system isn't working for me too well yet.
I decided on the Onkyo HT-S5500 unit due to the majority of good reviews here on Amazon. I needed to increase the lack of sound coming from the underpowered speakers from my Samsung TV. Ordered the system and chose one day shipping, got it the next day.Assembly wasn't too hard and the speakers were placed in their correct spots and I began to run the wires (included) into the reciever. One wire was too short for the farther tweeters.
Onkyo HT-S5500 7.1-Channel Home Theater Speaker/Receiver PackageI ser up my Onkyo 7.1home theater in under two hours and have my DVR, Blue Ray, and XBOX All connected to ny tv through the Onkyo receiver. It come with a calibration mic for tuning your speakers to your listenening environment and then you can pick audio presets for every type of audio from movies/tv, music, games and more for the most realistic sound you could ask for.
I took one star off because the reciever goes into setup mode randomly. Very weird. I have to make contact with the metal part with the mic input. Very strange.
Repair shop said Onkyo took forever to ship the parts. Worked great for 2 weeks and than failed again. Tried the Audyessy method mentioned by another user and it still didn't work. Took sub to buddy's out and it didn't come on with his Denon Reciever.Finally dropped it off today at a recycling facility.
I run my PC, 3D Bluray player, cable TV and MP3 player through the reciever and all sound great. Plenty of sound options. Live HD concerts on TV sound incredible.I have it in a 16'x20' room with one open wall(8ft ceiling), set-up in the high/front speaker config, with the sub in the corner.
I have owned the 5500 for about one week. I took it out of the box, connected everything and it worked. I then disconnected it all, installed it, ran audyssey and it worked... for half of a movie. The sub died, and will not turn back on. No light no sound, unplugged plugged back in. Tested outlet. Changed rca cable. Re ran setup both audyssey and manual. Reset crossover.
Well, it was easy to hook up, but the sub isn't working out of the box. Now, I'll need to mess with settings to see if I can't make the sub work (this shouldn't be necessary). I'll mess with that tomorrow and keep my fingers crossed, otherwise it's going back.Now for a bigger issue IMHO. We hooked my son's XBOX360 up via HDMI and then connected the receiver up to a 55&#34; TV that we placed in the basement (no HDMI).
Only negative I can think of is the cheap speaker wire but I didnt use it. I have wire running through the walls in my house, I would recommend 16ga wire and buy some good bananna plugs for the reciever speaker for hook up.....much cleaner and positive connections. The remote is straight forward and easy to use and the on-screen menus are awesome! I would definetly recommend the 7.1 over the 5.1 to anyone.
He did gave me the authorized service center address :  ADAMS Electronic,  7128  Edinger Ave, Huntington Beach, CA 92647, phone number is 714-848-0110. I asked for the supervisor, Kent asked me why?.... Finally he did connected me to the supervisor's voice mail I left message for her to call me back. Let's wait and see....  People, listen to what everyone is saying, do not make a stupid mistake that I made.
Answer: No, the system uses wires, but it is easy to install since all of the cables are color coded.
