You can’t and we did that for a reason. Phase tuning is, for the most part, something we encourage people to stay away from. It is there and useful only for the rare occasion when the phase of the incoming AC is so far off from what’s expected that our PLL
can’t lock on it. That’s super rare. For the most part, 99.9% of people will not need it, so adding it to the remote would be a mistake.
I get clearly the best “Improvement Factor-curve” when I use the Phase Tuning in the “Negative area”, minus you know, and I wonder if it’s possible to get the best “Improvement Factor-curve” with the Phase Tuning on either - or + when your AC is perfect and don’t need any Phase Tuning?
I’m thinking of that I must use -3 on the Phase Tuning to get as good “Improvement Factor-curve” as possible so according to that my AC shouldn’t bee in perfect phase.
I wonder about this to learn more about the Phase Tuning, if it’s something that we should use to get the very best “Improvement Factor-curve” we can out of our P15/P20’s or if the “Improvement Factor-curve” is not that important and that we shouldn’t care that much about it or do anything we can just to get att better “Improvement Factor-curve” and that we should only use it if we REALLY know what we are doing, like very few of us normal people are since we don’t have any instruments or knowledge about how to check our AC’s phase.
I use phase adjustment +10 as it results in the lowest output THD. If I set phase adj. to 0 or less then +8 I get dramatically worse values, values that can be greater than the reported input THD.
I have a P10, my current incoming THD 2.7%, with PT set to +10 output is 0.1 or 0.2%. With PT set to 0, output THD is 0.5% and PT set to -10 output THD is 2.2%
Likewise, output voltage is 120v with PT set at +10 (configured P10 at 119v). With PT set to -10 I get 111v output!
I’ve been running MW6 and +10 PT for over a year for what it’s worth, no harm to any device.
Am I in the super rare group with messed up power phase?
If the phase adjustment gives you lower THD then it’s fine to use it though yes, I would suggest you’re in a rare group with some pretty messed up power, Thank goodness you have a Power Plant.

That is my experience too. At “0”, P10 output THD is worse than what’s coming from the outlet. At 9, THD is always 0,1

I always (almost anyway since I’ve seen a THD of 0,2 one time) get a THD of 0,1 but I still get a clearly better Improvement Factor-curve with my Phase Tuning on -3?
Do you care most about the THD from your Power Plants and not that much about how your Improvement Factor-curve looks like?
I’m the other way around, I look most on my Improvement Factor-curve even if it gives me a THD of 0,2 instead of 0,1
Is there a meter or value for Improvement Factor-curve on the P15?
Or are you referring to the oscilloscope view?
I mean the one that has the “name” Improvement and on the top of that meter you have the text “Factor”
That “VU-meter” only exist in one place so if you find anything with the text “Factor” on it you have found it.
I have a P10 so I was not familiar, thanks

Yikes- you should not be using any Phase Tune! Your incoming THD is not bad, around the same as mine.
It’s not about tweaking the settings so the numbers on the screen look best. Listen (and watch) with your ears (and eyes) and check for differences in quality!
I think you’ll find you’ve degraded your system’s performance with Phase Tune set to 10!
I get lower THD out, from 0.8% to 0.2-0.3% by adjusting phase to +3 on my P10. Incoming is 2.8%-3.2%.
Is the power company compelled to provide power in phase? Meaning, can I call my local utility and they’ll know what I’m talking about and investigate/repair the cause or will they look at me funny like when I asked them to measure the DC on the line?
I also find that MW/SW affects the reported incoming THD %. Why would adjusting the output parameters affect the incoming power? Seems fishy to me.
In my case thd varies from 2-5% moment to moment and have used auto tune to
optimize the phase setting for incoming power…
For me the multi wave level 2-3 setting gives me the best blend between sine wave
sound quality and multiwave.
On my P15 seems best

I’m a bit late to the Multiwave game, having had PS Audio regenerators for about 10 years, and currently own a P5 (which I may upgrade to a P12).
My experience with MW on level 6 is:
-
improved image quality from my Sony laser projector: the video is a bit brighter, sharper, and “cleaner”.
-
reduced AC line noise coming from said projector. There is a slight buzz if you put your ear up to the speakers when the projector is gone. This is almost gone with MV 6.
-
however, it’s not all rosy - the audio has changed - treble seems to be significantly reduced, so voices sound odd
I’m using very revealing tube gear and a Denon AVR…
Experimenting now with MW < 6…

Tubes love well regulated voltage, me thinks!

Hey nikolay…
What you experienced at mw 6 is exactly what I experienced…as well as
loss of detail in on notes fading away in space, attack decay and presence
are sacrificed at levels above 3 for my system.
For thin sounding tracks have discovered that mw levels 1-3 are best at giving
body as while maintaining the qualities of sound listed above. Choosing mw
1-3 has given me very good results.
It is a matter of exploring to find which best suits your tastes.
My preference overall is sine wave.
Best wishes,
Merry Christmas

So what does that imply re: sine vs multi wave?
Thanks for your comments.
I may use sine for music listening and MW 1-3 for movies.
I also noticed that with MW on THD in decreases, as does THD out. Why would THD in decrease? Also, power consumption decreases with MW on.
I also have to set output voltage to 121 to get 120.3. Why wouldn’t it be more accurate- in that setting voltage to 120 gives you 120, rather than 119?

nikolay…that is a very question to which I have’nt an answer as to why with mw
thd in decreases…
Does this happen each and every time you use me? My thinking might be that an
outside of your P5 such as power demands created outside your P5’s environment
such as ac or furnace that "just so happened to kick in at those moments.
But really idk.
" also have to set output voltage to 121 to get 120.3. Why wouldn’t it be more accurate- in that setting voltage to 120 gives you 120, rather than 119? "
With this statement…I’m thinking it may be best to shut down your P5 un plug from wall
wait a few seconds plug back in then re-boot so that the chip that controls the P5
can reload the software afresh…this often times resolves a lot of unusual issues…
This has worked for mine as well…give it a try if you haven’t already done so.
Beyond that try and reach out to jamesh our whizkid he will know what to do for sure.
Please do get back to us with your results.
Best wishes and
Merry Christmas

By sine vs mw what is meant is the quality of sound using sine
vs the quality of sound using multi wave.
Yes, thanks. Sorry, I was referring to @Serhan’s post about tube voltage…
