Onkyo tx-8211 protect

The manual for the tx-8211 says that the total impedance for when you have both A and B speakers on are 8 ohms before it goes into protection mode. So look on the back of the speakers and read the impedance and add them up for that side of the speakers. You can wire them in series and it should fix them. I know this is a tad bit late by yknow two years but I’m bored and have nothing else to do.

Check all of your speaker wires and speaker turminals. I bet there is a short.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

make sure that somehow the wires didn't get loose from the speakers in the back. Protect means that it's overloaded. Did you change the plus wires with minus wires maybe. Check to make sure all the wires are good.

I don't think you can fix it, unless you're skilled with electronics. Possibility that something has occurred internally with a circuit board etc so the system shuts down in order to protect itself from catching on fire etc. Get it services. Might not be too bad of an issue, but certainly not a bypass.

Your tuner will be the limiting factor regarding sound. The Onkyo accepts any stereo analog input via RCA connectors, period.

Those "black/red spring loaded wire inputs" are speaker outputs and if you hook one of those to an innocent audio device's Line In connections you might kiss it all goodbye.

Read the manual...

Find the cause of the problem, either a blown fuse or a shorted output stage. Not so easy to find the cause but you can try. Or it could be caused by other things.

Eliminate the short or overheating problem it thinks exists. Disconnect all speakers first to see if one of them is the culprit. If it's internal, take it to a shop.

It's the Tape 2 button - unclick it.

the system protect is usually displayed when a condition of short or shorting is occurring in the speaker wiring or the voice coil of any of your speakers.... thte circuit of you reciever is trying to protect itself and you from a very costly repair,,,so it you have another set of speakers try to use them and see if the condition still exists and if it does the problem is in the output section of the receiver,,,and if the protect no longer exists you have fixed your problem,,,good luck
