Latest P5/P10 variable MultiWave code version 29


#1

The latest P5/P10 code is at :

http://updates.psaudio.com/Regenerator/11-056-01-X-FMC-29.zip



Fixes:

1. Fixed MD=VD to work on demand

2. Fixed CleanWave/Multiwave reset to 0 issue.

Thanks Dennis. I think this is actually firmware version 39 rather than 29. Why are the zip file numbers different from the firmware version number?


#3

No it is 29. The version numbers are different because the the main code is at 39 but the firmware release is at 29.


#4

Installation went OK. I wasn’t sure when it was finished as I had to turn it on at the front panel after it installed.


#5

Installation went ok for me too. As per any P10 firmware I’ve done, all of them have come up with all five zones off. Enabled these as required.

A quick listen seemed to confirm that none of the sonic improvements, mainly timing, have been lost with this new version.


#6

The installation went fine. All programming and settings came through intact.


#7

With a Multiwave setting of 6 , my Pass amp now rarely goes out of Class A . So it does increase the amplifier power as promised.


#8

Fascinating. Thanks!


#9

@papaned good to hear, thank you! BTW how do you know it’s not going into AB and rather staying in the A class?


#10

Interesting about power output my NC400 show less load on the P-5 while at idle only 10% where it use to be 11%


#11

If you’ve ever wondered what that meter is doing on the front panel of every Class A Pass amp, it indicates when the amp is driven into Class AB-past the 12:00 position. Very analog, but very effective in showing it’s headroom at any time .


#12

@johno@datacom.co.nz with MW 6 my P10 show about 15-20% lower power usage and therefore also lower load.



I’m just not sure if it’s only P10s metering, or if I will also get lower electricity bill at the end :))


#13

Perhaps we may here from PS Audio on this seems the units are operating more efficiently if so that could attribute to improving SQ


#14

I just upgraded the firmware of both my P10s to 29, one on the stereo and the other in my home theater system. I am listening to my stereo now. I might be imagining it, but it seems to sound a bit better :)>-



BTW, I have a tubed preamp. Is use of the new MW have any negative effects on tubes longevity?



Thanks,



Bob


#15

The current version of multi-wave is perfectly fine for tubes. It can make some transformers a bit louder than usual.



Try it and see what you think.


#16

Another interesting thing that I noticed is that MW level 6 shows less load and power consumption in my 2 channel stereo system, 43% in Sinewave vs 36% in MW 6. I wonder how accurate that these figures are though? However my P10 does appear to get a bit warmer with MW though. I have not used the new firmware in my home theater system yet. It will be interesting if I get similar effects there?


#17

What effects if any does multi wave have on switching psu ,s ??

As this type of psu does not stay in a steady state as does others

#18

I would think that MultiWave would be good for switching power supplies. More energy available for more of the cycle should make switching PS job easier. I am not sure if there would be any interaction with switching PS that have power factor correction.

Hi, specking from personal experience the SMP600 with the NCORE, I experienced a significant improvement in SQ after updating my P-5.


#20

Well all rity then. I am good. I would like to use it for my CPU .

What settings are you using ?

Thanks
