Wondering if anyone has any ideas as to why my AVR power consumption seems to be fluctuating...
I have been using a cheap plug in power meter to check the power consumption of my various bits of audio hardware, and my AVR consumption appears to have two different levels!
When I first plugged it into the power meter the consumption was generally between 76 and 82 Watts. I thought that this was rather high, at idle particularly, as it is a Pioneer SC-LX86 which utilises Class D amplification, and it is only powering the center, wide and surround back channels. (I am using additional power amps for the L/R and surround wide channels.)
Anyway, after a couple of weeks I moved the meter to check something else. When I reconnected the power meter to the AVR about a week later it was only using between 12 to 13 Watts! (This was actually what I had expected it to be using when playing stereo or 2.1.) Anyway, this was the average draw for several weeks of use. Then after using the meter to check something else for a while, when I reconnected it to the AVR it was back up to it's original draw of between ~76 - 82 Watts! I have been using it for about three weeks since and this appears to be the average draw again. This is when playing stereo or surround formats at various volumes. Volume level and channels used does not seem to affect the power use significantly. Very weird.
I am really confused by this as ~80 Watts seems like a very high draw at idle however I am not sure what it should be to be honest!
Anyway, any insights or advice most welcome...
Have attached the manual for the power meter.
Thanks in advance!
