Question about Onkyo TX-8211 Receiver

2 Answers

Vollume trouble Hello, I have an Onklyo TX-8211 FM Stereo/AM Receiver. A few weeks ago, it started to cut the sound when the volume got beyond a certain point. If the volume is not very low, the sound will cut out. The display flashes "PROTECT", as if it is trying to protect the speakers? It is very annoying. I can only listen to the stereo at very low volume. Thanks for any help! H.

Re: Vollume trouble

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

TX-8211 FM Stereo/AM Receiver Display changes to PROTECT & shuts the power

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.

TX-8211 FM Stereo/AM Receiver All has been fine

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 have a TX-8211 but I am out of town looking at Internet Radio tuners. Can you tell me what type of inputs are on the Onkyo? I know it has the black/red spring loaded wire inputs but are there other...

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.

I have an ONKYO TX-SR606 receiver and I am trying to listen to FM radio using more than just the center channels. I have gone through the setup screens for the tuner and only Analog choices are available....

In reality the correct way to listen to radio or any music source for that matter is in 2 channel stereo. What this means is that the front left and right will play and also the subwoofer. If you absolutely want all your speakers to play while listening to fm, than press the Multi channel button and set it to direct, or any other sound field that you may desire.
Good Luck

I have a new Onkyo TX-SR508 receiver. When listening to FM radio the audio cuts out repeatedly for anything from a few seconds to a minute. Power fluctuation is very unlikely to be the problem. Signal...

Does the display show "tuned" or "FM Stereo"? This would normally indicate a good reception. The tuner has a signal level threshold and if the signal gets to week, the receiver mutes to prevent noise in the speakers. Swithing to mono make reception less intolerant. Does the problem also occur, when you switch to mono?

Sound cutting out

sounds like the tape monitor may be turned on. First place to check anyways. If it is not the problem, I am happy to talk more about it with you and do some more diagnoses.
