Re: onkyo tx-sv727 Protect displayed
First thing if it says protect, check the fuses inside the system they may of blown .When choosing wire gauge, consider the quality of your components and speakers, the overall sound quality you're trying to achieve, and the budget you're working with. Also, keep in mind the distance between your receiver or amp and your speakers long wire runs can cause significant power losses, and thus require thicker cable. You can use this as a guideline Distance from speaker to amplifier Gauge Less than 80 feet 16 80 to 200 feet 14 More than 200 feet 12

Get a RCA cable and connect from your amp where it said Sub Woofer in the Pre Out box in the back of the amplifier top left hand side and take it to the "Sub In" located in the back of your Sub woofer bottom right hand (White round connector).
1. crossed or damaged speaker wires- make sure that the positive and negative is not crossed at all. inspect the wiring for any loose strands of wire that might be crossed, touching the speaker frame or touching the metal case of the amp. look for any damage to the wires. use new speaker wires, if you need to.
2. improper speaker ohmage- verify that your speakers are 8 ohms or greater. ohmage is usually labeled on the back of the speaker, and will have the greek letter "Omega" ω next to the ohmage rating. example: 8ω or 16ω.
3. blown speaker- push in on the woofers, it should move freely for an inch or 2 before bottoming out. if it feels like its scratchy or rubbing or there is any resistance before it bottoms out, then the speaker's voice coil is melted.
The onkyo should still have a speaker A/B selector in the menu.
Check on the back panel for speaker A/B.
If it has or you decide to use Zone 2 you will need to set the sound programme to "stereo" so the rears and centre do not work.
You can still use a digital source.
You should be able to display the amp's menu on the screen.
Hook up "monitor out" (Yellow) via RCA connector to one of the "A/V inputs" (yellow) on the tv, this will show you a display of the menu and will make it eaiser to navigate.
Please check your speaker cables. Make sure that all of them are seated properly, none is touching each other or to the body of receiver.
Are you using banana plugs for connecting speaker or just directly. Some times even a little tiny frayed speaker cable touching the receiver could trigger the protect mode. Be careful, since protect mode is sometimes not fast enough to activate and it could blow a few trasistors in the power output circuit.
Please take out all the speaker cables, unplug your receiver from the mains and try to restart without any cables plugged. If it powers on then you are lucky.
If not and the receiver still goes into protect mode or wont turn on then it possible that there are bad connections on the main board or have some blown transistors. How old is your system? if its still under warranty then you should contact Onkyo immidiately.

Greg- Powered subs are better than non-powered subs (also known as passive subs), anyway I see the TX-8511 has no sub pre-out on the back panel, so you need to decide what sub you will use and run from the receivers left and right speakers output into a subwoofers speaker in from speakers then back out to speakers, look at the back of a subwoofer and you will see like 4 sets of speaker hookups 2 in and 2 out, what this does is takes the low end or bass and drops the signal to the subwoofer then takes the mids and highs out to your left and right speakers, unless your regular left and right stereo speakers have large woofers a sub is the way to go.
I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1.
According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected.
Hope this helps.
