## Overview

The WAudio W-3900 AC Power Filter is a premium power conditioner designed to deliver clean, filtered electricity by reducing electromagnetic interference and protecting connected devices with surge and overload safeguards.

## Description

Clean electricity to improve the performance of your audio-video system. The electricity network in our homes or workplaces is exposed to different interferences for instance electromagnetic interference (EMI) generated by appliances connected to the same network (refrigerators, air conditioners, computers etc.). These interferences are not only produced inside your house or office but by all appliances in your building or even outside it and can differ on the time of day or week when the traffic on the electrical network changes. All these interferences which we call noises can get into your AC power and interfere with your system. This “dirty” electricity can have a negative effect on performance of your audio-video system. WAudio power noise filter is a great way to limit the negative noises from your electricity and to isolate your system from the contaminated power and has a feature to indicate the correct power phase.Thanks to the W-3900 you will be able to enjoy a better quality of your audio and video equipment.The contaminated electricity has also a negative impact on internal circuits and power supplies of your equipment and because the W-3900 works as a buffer between the wall socket and your gear it will help to increase the longevity of connected components.Removable IEC type power cord gives an option to upgrade your system with a premium audiophile power cable in any time.Specification:Max Spike Volt: 3000VMax Surge Current (8x20s): 1000AMas Clamping Volt (8x20s): 470VNoise Filter: >-10dB (2~100MHz)AC Power Rating: 110~125V 50/60HzKit Contents:W-3900 power filter x 1 power cord x 1

Review: Works but could use even a little documentation! - Little to no info online, so I'll share what I've found. Quality construction and does what it says on the tin. Once I worked out some kinks (see below) I noticed a significantly lower noise floor between mic, interface, and cans. That being said, it had some weeeeiiiird kinks, and I had to try about 4 different combinations of how I plugged in my computer, USB hubs, audio interface, lamp, and external HDD enclosure. Before I got it right, really strange things were happening to my audio. I've no idea why. Nothing in my prior experience or knowledge explains why the sound would start to smear out over time, like jam spread slowly over toast. The lower noise floor I cannot scientifically attribute to the unit alone, as I took the opportunity to re-route all my power cables away from all my audio and video cables, whereas before they all disappeared down the same hole in my desk. Cable management is SO satisfying when done well, is it not? Anyhow, ymmv. I also don't know how the phase indicator is supposed to work. Mine is lit, but it looks half-lit, so my gut tells me that means it's getting a signal that's both in and out of phase, but moving things around didn't change that. I probably should've mounted it the other way round, or not so close to the underside of the desk, but until I know for sure I'll stick with what's working. I think a clue I found on the Asian version is to make sure to use enough of the filtered outlets. At first I thought I'd save them for something special, but usb3 generates a lot of noise (look it up) and I'm still repairing my hafler so no hifi review at this time.
Review: Una buena compra - Se nota una diferencia notable en la calidad del audio, la compré más como protección que como acondicionador de sonido, pero logró darle más claridad a las frecuencias altas, ampliar el escenario sonoro y la imagen estéreo. Las frecuencias bajas suenan más definidas. Lo uso con Cambridge Audio y bocinas Focal.

## Questions & Answers

**Q: Where is the waudio ac power purifier with surge protector made?**
A: China

**Q: Does this protect against brownouts / under current as well, or just surge and spikes?**
A: No. You'd need a UPS for that.

**Q: Will this help clean harmonic distortion put into the line from a generator?**
A: This filter is very simple, it will clean some types of RF noise and that kind of thing, but it sounds like you are looking for something to re-shape the 60 Hz sine wave. This will not do that.

**Q: since this is also a surge protector, what is the joules rating?**
A: 1875 joules rating.

### ⭐⭐⭐⭐⭐ Just buy it!
*by A***. on 13 January 2020*

After reading and watching good reviews on this power conditioner I decided to take a chance and buy it (also bought a 1m w audio power cable to go from this to the wall) I am replacing a Monster HDP 2500 power conditioner. The difference is night and day. The W-3900 just changed my whole system it is smother much more dynamic and the bass is absolutely incredible now. Iam using Kef Ls50's and I was considering buying a subwoofer to pair with them but it is not needed anymore. I also have SVS ultra towers and everything got boosted mid, highs and bass. My system sounds good all the time now, where before with the monster there would be peak times of the day it would sound good and then just terrible where I would have to shut off my system. The build quality is also very good anything you plug into it is very tight. For $250 it is a great upgrade.
