Amp went into protective mode, I think

Still, the spec doesn't say max power, might try that article.

It does spec the maximum power transformer draw from the AC supply and that is 700 watts. So that means that the max power available to the speakers will be around 450 watts at most and actually likely a bit less, but 450 watts is a good number to round it off at, given the 700 watt max power draw.

Show me the word maximum....I didn't see it. Just says power consumption....

This from the spec. sheet.

Power Consumption in W	710
Power Consumption No-Sound (ECO on/off) in W	65 W / 110 W

In any spec. sheet on AC power draw, the idling and max power draws are quoted. If you know how to interpret a spec. sheet the lower number is the idling draw, and the higher number the maximum power draw.

As an aside that it also why these multichannel power amps, are also nonsense, as you can't get a big enough transformer in the case. If you want external power, and in any robust system, then you need to build it from two channel amps, or mono blocks.

...a picture frame leaning on a bookshelf slid down right in front of me and landed flat on it's back. Loud enough to shake the upstairs furniture...

Any local reports of an earthquake?

Wow! Talk about a earthquake with your set up huh. Never heard of something happen like that.

Maybe it was an actual EARTHQUAKE, which could cause transient ELECTRICAL problems.

I am sure it did go into protection. There are just too many amps in these modern receivers, powered by inadequate power supplies.

Members, you really need to look at specs and understand them and be much more careful about what you purchase.

Just take a look at this spec, copied from that receiver's manufacturers speck sheet.

Power Output (6 ohm, 1 kHz, 0.7% 2ch Drive)	165 W
Power Output (6 ohm, 1 kHz, 10% 1ch Drive)	235 W

There are NO specs quoted for more than two channels driven. You don't have to guess why, you know.
So that means that the power supply is so undersized as to be useless except at low to moderate volume. No specs are given for using more than two channels. But you can extrapolate that the receiver will be woefully deficient in power if four or more channels are used. So I can be certain this power supply was overloaded and went into protection. In any event the power supply has a maximum power draw of 700 watts. Of that at most 450 watts will be available to the speakers total, at the most, and may well be less.

It is totally dishonest to have a nine channel device and only quote a power spec. for two channels driven. Few will buy a receiver with 9 channels to power a 2 channel system. But honestly that is all that receiver is fit for.

In current program there is actually a lot of power going to speakers other then the front three, as the OP has found out. This was something discussed on a recent Audioholics video presentation.

That receiver is only fit for low spl. usage. I would never recommend anyone purchase a unit with that specification for high spl. levels at any time.

I have the 6011 (lower model), have had it plenty loud n lively and never ran out of power...

I also had all Ultra speakers at one time too. They're not a particularly hard speaker to drive. I say check all your connections and make sure you don't have some bare wires or stray strands.

No def not, unless the dual PB16's caused it, which I doubt.

Still, that's not a max power consumption spec, try that AH article as to how it works.

Hello machine and all. I have the sr7012 and my receiver did that to, out of the blue.
Oh yeah manic I did . Went and got a fan and and Panamax for the power. But only for a few days later when it just came on for 10 - 20 seconds and shut down over and over again .
So started to disconnect one piece at a time trying to find the problem till there was nothing connected except the power cord and still won’t stay on.
boxed it last night to ship for repair ( sending out today ).
when I get the news. Bad or good. More than glad to fill you in Shaking in my boots

I had a friend over this morning and decided to throw in fury on 4k so he could experience the set up.

Had both PB16s running at -3dB and the SR7012 set to 75, which 75 is the highest I have ever pushed it in the past, as it is all I can take. About 20 mins in to the movie crazy amounts of sub bass and loud explosions were going off and the amp shut down and the power light was blinking red. I waited a few seconds, turned on the power button, lowered the volume to 69.5 and it was fine for the rest of the time. The amp was barely warm, and the front three are powered by external amps.

Any idea what may have caused this? First time it has ever happened, but I have only had the system running at this volume level maybe 10 times in my life, and never with sub bass extension like this movie has. Picture frames that were leaning against walls in the room and upstairs were knocked over during the movie.

I stand by my earlier comments. If you are in for the long haul, and putting together your for ever system, then do not buy a receiver. The number of power amps in one case and driven from one power supply, has now reached the absurd. In addition, if you go the pre/pro route, you will be well positioned for when active speakers are the rule. If everyone would see the light on this, then pre/pros will gather economies of scale and the prices drop, so they are cheaper then AVRs, which they should be.

You shouldn't make such an assumption. Take a look of Yamaha's specs such as the one for the RX-A6A:

Power Consumption 500 W

Maximum Power Consumption (All ch driven 10% THD) ( [Asia, Brazil, Central and South America and General models] 1160 W

So Yamaha's is being more specific as you can see the word "maximum", but still vague, or even theoretically incorrect to specify it that way. Any knowledgeable EE will tell you amp power consumption spec that does not specify the conditions under which the measurements were taken is not very useful at all. You can more or less specify maximum consumption for a bank of resistors, or an electric fan at the maximum speed but not a power amp that amplifies music signals, and even if the amp's load is resistor with fix resistance such as 8 ohms, the consumption will be vary with the input voltage and volume setting, so what the heck is "maximum". I suppose it could be at the point the protection scheme will shut it down, but then how about the duration. Thermal overload protection typically is not just load dependent but also time dependent.

As I mentioned many times, the power consumption specs audio amp, avr manufacturers use are a mess, no one knows exactly how the numbers were derived, except the manufacturers themselves. And to get an answer from the manufacturer, I wouldn't rely on the response from their level 1 customer support rep either.
