Physics 101 
Energy can neither be created nor destroyed.  Unless we choose to ignore it, we only have two choices: It can be rerouted or it can be converted to another form of energy.  It cannot be destroyed as some marketing materials might suggest.

So let’s assume we definitely want to eliminate the noise, not just hide it somewhere where it can still cause trouble. All we can do is convert the unwanted noise to another form of energy: heat, light, or movement, but we cannot destroy it.  

There are several ways to convert it but most have problems: movement makes sound, so we can’t do that.  Heat allows the dissipating device’s properties to continually shift, so it’s not predictable in its effect. What we really want is a totally predictable elimination of a totally random destructive event – AC line noise.

Physics defied? 
PS Audio’s Noise Harvester™ does, in fact, eliminate a measurable amount of power line noise from your home.  But, we don’t do it by defying the laws of physics.  We do it by taking advantage of them.

The Noise Harvester™ is a plug in module that can be placed on any AC receptacle.  Once connected, the Noise Harvester begins to harvest and redirect the AC line noise into a storage tank and then converts it to light. 

Plug the Noise Harvester in and watch it go to work.  Each blink of the Harvester LED is power line noise gone forever.  It’s been converted to light. 

But is it measurable? 
You bet!  You can count on PS Power to provide real power solutions that are both measurable and audible. 
If we want to measure the results of the Harvester™ we first need to make sure there’s a steady source of line noise to view on the ‘scope. 

There’s no better source of line noise than a simple light dimmer.  You know, the kind you probably have in your home that makes everything buzz?

This first ‘scope photo shows what dimmer noise actually looks like if you were to ‘freeze’ it. The ‘noise event’ is being shown both in time and level on the ‘scope.  See how jagged and nasty looking it is?

What you want is less of this nasty waveform, or even better, just a straight horizontal line with nothing vertical at all.  The loudness of the nasty buzzing noise is represented here by the vertical information. 
 
This second photo shows the same noise, but notice how much smaller it is.  Why?  Because a single Noise Harvester was added to the line, permanently removing almost half the noise created by the dimmer.  

While it’s doing this, the Harvester is blinking like crazy!  

When more is better 
So, if one Harvester is reducing line noise, what happens when you add multiple Harvesters?  Improved noise reduction.  

Harvesters work in parallel, each removing 8 to 10 watts of line noise each day.  The more you have connected, the more wattage converted and the lower the noise on your power line.

In our sound room we have a small extension strip with 5 outlets. We’ve plugged in five Harvesters, plugged the strip into the wall, and the background noise of the system has gone down dramatically.

So not only is the effect addictive, it’s also additive.

Here are the facts
Typical power line filters either redirect the AC noise from hot to neutral or place a resistance between the AC source and theconnected gear. 
 
The more common Series Filters like those from Monster Cable, Panamax and even our own pas sive filters add resistance at noise frequencies between the AC outlet and the equipment, thus building a partial barrier between the noise and the gear. 

They work well to block some portion of noise from the equipment, but they don’t lower noise on the AC line.  Power line noise is not actually eliminated on the power line itself, it is simply redirected away from the equipment and this is far less effective than actually eliminating it. 

Only the Noise Harvester collects the noise, removes it from the house power line and then converts it to light.  So you can see noise being eliminated. 

Works great as a measurement tool 
Harvesters work great as a noise measurement tool as well.  Plug the Harvester in at various outlets in your home to discover which are noisier than others.  By narrowing down the noise culprits, you can then decide where to place the Harvesters for best benefit.

So, does it replace my power conditioner? 
No, it supplements it.  Power conditioners, Power Plants or any type of power line noise filters reduce line noise by a certain amount depending on their design.

The less noise you have on the line in the first place, the better your power conditioner will work.  So, the Harvester is your first line of defense against noise.  

Use as many Harvesters as you can to lower the overall line noise in your home.  They can be placed anywhere in the home to do their job and the more the better.

Once the line noise has been harvested, then you use your power conditioners, Power Plants or other noise filtration systems to feed your equipment.

Think of the Noise Harvester like a water filter.  Water filters don’t produce pure water.  They produce cleaner water than what went into the filter in the first place.  So, the cleaner the power line is to start with, the cleaner the power going into your equipment is. 

The bottom line?
With any audio system, no matter what brand of power conditioner you’re using now, you’ll hear the improvement. Plug in just one Noise Harvester and the improvement will be both immediate and obvious.

However, as we’ve said, the more Harvesters you add to the room, the lower the noise level on the line. 

Which is cool, since they’re incredibly small and affordable devices.  They make an immediate sonic and visual improvement. 
 
Buy a 5-pack and save 
You can by Harvesters individually but a much better deal is to get a 5 pack. 

Harvesters work great for lowering noise as well as act like a noise measurement tool to discover noise.  Your system will benefit greatly from the addition of this revolutionary new device.
