PS Audio Noise Harvester

[Paulhoff]

It's more like a short-circuit between the headsets!

Circuit would imply that there was something complex there..............

Aren't you interested to know why it happened?

Here are some possibilities:

1) The cable I used to power the Harvesters was like an antenna that picked up noise. The noise entered the AC outlet.

2) The connector of the cable was poorly shielded and noise entered the AC outlet.

3) Turning the Harvesters so they were facing the wall made less EMI enter the audio system. EMI comes out from Harvesters.

4) Turning the back of JuiceBar facing the radio broadcast towers helped pick up more RFI because it is little open at the back. Harvesters removed some of that noise instead of letting all of the RFI go into my audio system. Similar to Shakti stones (I haven't tried).

5) Harvesters pick up noise from the air and remove it.

6) Heavier cable plugged into wall pressed the AC outlet tighter sideways. Radio towers are pointing directly at the AC outlet.

7) AC noise from within the cable goes out from it and into the air.

8) Statement power cable has 4 shields and keeps the AC noise inside before entering the Harvesters.

9) Statement has a shielded connector plugged into the wall.


Everything in my system is shielded except for the cable powering the Harvesters.

Here is a picture, you see the AC outlet, I have wrapped it in ERS Paper and the only way in is through the unshielded AC connector.

Here is a video also: http://www.youtube.com/watch?v=6KAz5vLV2_E
In the video you can also see the Harvesters blinking when using CleanWave of Premier Power Plant.

Here's another possibility:
You have a good imagination, and not much actual knowledge.

I didn't like Harvester before because it showed problems in my system.

In my first setup 1 Harvester made bass too big, but then I found the problem. The rubber bands of my isolation foot under the amp were too stretched, so I replaced it with stiffer rubber bands and it made bass stronger. Too loose rubber bands gives a too loose and slow sound. Stiffer rubber bands gives a tighter and faster sound. Read my first impressions, I didn't like it at first: http://www.head-fi.org/forums/showthread.php?t=218209

The Solid-tech Feet of Silence gave exaggerated bass, it wasn't neutral. It also made the highs appear whiter because the low end was so loose. It gave fake transparency and dynamics. When I replaced the Feet of Silence with Magix levitation feet the problem was solved: http://www.youtube.com/watch?v=0dKBIWDKVE8
I got longer attack and decay, it gave true dynamics. Bass was clean instead of muddy. The edgy whiteness was gone and there was more detail.

And now in my 2nd setup the problem was RFI entering the AC outlet through the cable plugged into JuiceBar + Harvesters.

Aren't you interested to know why it happened?

Why, of course!

Here are some possibilities:

1) The cable I used to power the Harvesters was like an antenna that picked up noise. The noise entered the AC outlet.

But, wouldn't the harvesters take care of that?

2) The connector of the cable was poorly shielded and noise entered the AC outlet.

The AC connector? Nah, the amount of noise that it can pick up is minute.

3) Turning the Harvesters so they were facing the wall made less EMI enter the audio system. EMI comes out from Harvesters.

Yes, they are absolutely radiating it. In the form of light, of course, but still you can never know what those pesky photons might do to music.

4) Turning the back of JuiceBar facing the radio broadcast towers helped pick up more RFI because it is little open at the back. Harvesters removed some of that noise instead of letting all of the RFI go into my audio system. Similar to Shakti stones (I haven't tried).

Are they in a straight line between the broadcast towers and your equipment?

5) Harvesters pick up noise from the air and remove it.

Not even according to the producer. And you just surmised they might be transmitting noise. Say, you are just making wild guesses now, right?

6) Heavier cable plugged into wall pressed the AC outlet tighter sideways. Radio towers are pointing directly at the AC outlet.

Uhh, generally, radio towers transmit in all directions. That is what they are there for. Also, what kind of radio towers are we talking about? Most have wavelenghts that are longer than the size of your outlet.

7) AC noise from within the cable goes out from it and into the air.

It does, yes.

8) Statement power cable has 4 shields and keeps the AC noise inside before entering the Harvesters.

Only, this is only a short way of the path of the noise. Also, the Harvester only harvests differential noise, and that is not sensitive to shielding.

9) Statement has a shielded connector plugged into the wall.

Again, differential noise.

Everything in my system is shielded except for the cable powering the Harvesters.

Shielded how? You are aware that all that shielding paper stuff you have pasted all over it has close to zero effect, the way you have placed it?

Ahh, hehe, who wrote the transscript of your soundtrack? .. Nevermind.

Anyhow, I think I have located the source of your troubles. In the video, it is clearly seen that you have an unshielded telephone wall-socket sitting right in the middle of the whole setup. With all the digital transmissions these days, telephone lines are a major source of EMI.

I think you need to shield that socket, or better still, connect a Harvester to it.

Where's the "spluttering and coke pouring out of my nostrils" smiley?

 

[Mr. Scott]

I already live in a poor house with holes in windows and stuff.

Well, think of the neat audio gear you could buy with the million dollars you'd surely win if you are right that you can hear the difference between three and four noise harvesters. You could fix up the holes in your windows and stuff, too.

What? I'm just taking his own logic to it's full consequence. If he believes what he writes, then that phone outlet is a major issue.

[Harlequin]

Shouldn't the headphones also be covered in ERS paper?

Hans

Is phone line connected to AC line? Is the phone line powered by AC?

If it isn't connected to the AC wiring then it's better that it's open. Then it captures some of the RFI from the radio towers.

What has AC to do with it? It is carrying EMF noise into your room and is radiating it.

You can't capture RFI and thus remove it from another place. Radio waves propagate in straight lines.

But the waves can reflect from objects right? So if RFI goes inside the phone outlet it keeps reflecting inside the wiring. If the outlet wasn't there the RFI would keep reflecting to other objects and into the audio system.

What makes you think it will do that?

If you think so, then why do you think AC outlets should be screened?

ES, an antenna works both ways. It transmits just as well as it receives. IF your phone plug can receive EMI signals and lead them away in the wiring, then it also means that any EMI that is borne by the wires will be emitted by it.

What waves are you talking about, water waves, we're having a heat wave, what waves................

This is a chase were no knowledge is much worse then a little knowledge!!!!!

 

[Paulhoff]

By the way, the metal cases of the equipment shield many magnitudes more then that ERS paper that you are getting ripped off on.

Paul



It is like putting that paper on an US Army M1A1 Abrams Main Battle Tank to protect it.
