Relative scale, yes.Isn't volume scale adjusted after calibration? On my LX305 switching depends on signal level too.

don't think OP specified exactly what measurement device he's using.Agreed, that's the way it should have been designed, "latched" would not make sense unless it was triggered by a fault event such as thermal overload and that's probably what was experienced during the test. Still, the OP has not posted more info about how he obtained that chart, such as, was it from some sort of the so called kill-a-watt meter, or a better meter that actually measure power consumption in terms of average, peak, etc.., and the load condition, was it just idling with different volume settings or actally playing music? Sorry if answer to my question about the measurements have been given by the op, I have only quickly browsed through the post once from beginning to end, so might have missed something.
don't think OP specified exactly what measurement device he's using.
I don't think it matters too much, though.
The device clearly shows that the Receiver switches (relay clicking) to a lower voltage rail after 25 minutes of low power draw. (I can confirm the switching, but not with measurements of my own)
OP has shown that the power drawn by the system gets roughly cut in half.
And they also stated that the power draw goes back up when the volume is turned up to -15dB (because the receiver switches back to the higher voltage rail)
No "power cycling" is needed here.
Presumably measured from the wall, where the change in amplifier draw from dynamic content is going to be minimal relative to the HDMI section, etc.Thanks, I just want to know under what conditions his metering (whatever device) was measuring, and regardless, the fact that the "power" was so constant, it would have to be either a) averaged over a long period, i.e. many seconds and/or b) playing contents that are highly compressed, without much dynamic fluctuations.
It's just bad data. The OP has provided no timeline of his procedure -- when he was changing volume, changing input sources, how did he measure the result, etc. It's completely worthless data.Guys, I am in agreement, but those graphs shows something very different that seems inexplicabe but obviously there are reasons.
What is inexplicable? All looks quite normal for me.
To be fair, though, those data are only "bad" for people who are perhaps being too curious.It's just bad data. The OP has provided no timeline of his procedure -- when he was changing volume, changing input sources, how did he measure the result, etc. It's completely worthless data.
Search for: smart socket power monitoring. Something like this:It doesn't latch into the low output mode.. as far as we know, when you crank up the volume, it will switch back to high output mode.
(I really need one of those fancy measurement thingies that OP has..)
Smart socket with power monitoring via phone app. It was basically live power consumption monitoring.Thanks, I just want to know under what conditions his metering (whatever device) was measuring, and regardless, the fact that the "power" was so constant, it would have to be either a) averaged over a long period, i.e. many seconds and/or b) playing contents that are highly compressed, without much dynamic fluctuations.

Worthless data? Nope. Everything is described exactly as I was testing it. Which part you don't understand?It's just bad data. The OP has provided no timeline of his procedure -- when he was changing volume, changing input sources, how did he measure the result, etc. It's completely worthless data.
This is sound of relay switching.After 25 minutes when watching movies there is that sound exactly as it is when you are powering on the AVR. I don't know how to call it.
No. It is not % on Y axis. Y axis = W. Peak measured W was 75 (or maybe 99 that is why it shows 99 but I do not remember ). I do not have the data on the app anymore but I can check it later today.Just one more question if you don't mind repeating (if you did provided the info before), is the number on the Y axis %? and what's that 75 W referred to, 100%? is it something you input into the app or the app select that automatically?
Why?If it is actually measured power, it is not possible for it to be so consistent regardless what you were listening to.
The measurement is power drawn from mains socket. Voltage is constant 120V (or 230V) and there is no way to include 8 Ohm for any calculationthe displayed "power" is probably/likely not actually measured "power" but voltage and then the app might just calculate power based on a fixed resistance, likely 8 ohms
