Convert powerline noise into harmless light. The Noise Harvester reduces unwanted noise and helps clean your AC power.

Get noise right at the source. The Noise Harvester is the world’s only device that actually eliminates line noise from the home’s power lines. Filters and conditioners either shuffle the line noise away or provide some isolation for equipment, but they do NOT eliminate or remove power line noise. Only the Noise Harvester removes line noise and converts it to another form of energy, light! Give your power conditioner a fighting chance by lowering the noise floor of the power line in the first place. The more Harvesters you add, the lower your noise floor. The Harvester makes a significant improvement in sound quality.


Energy can neither be created nor destroyed. Unless we choose to ignore it, we only have two choices: reroute it or converted it to another form of energy. That's exactly what PS Audio’s Noise Harvester™ does—not by defying the laws of physics, but by taking advantage of them. Typical power line filters either redirect the AC noise from hot to neutral or place a resistance between the AC source and the connected gear. They work well to block some portion of noise from the equipment, but they don’t lower noise on the AC line itself. Only the Noise Harvester collects the noise, removes it from the house power line and then converts it to light.


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. 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.



Power line noise: it’s everywhere. It comes from light dimmers, computers, cell phones, TV’s, even stereo and video equipment in your home as well as those of your neighbors. Your equipment doesn’t want these power line noises because they can cause a hard and bright sound as well as muddy up the colors of video. To battle them, we place filters between the equipment and the AC line. While these help reduce noise feeding into the equipment, they do not eliminate it. But now there’s a solution that works. The PS Power Noise Harvester™ is the world’s first true power line noise converter that actually eliminates power line noise – instead of shuffling it off somewhere else.

Measuring Noise

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. 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. 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.

Used as a 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. If you have an existing power conditioner or Power Plant, place the Harvesters before the device to clean power before entering the device. 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.
