Featuring automatic phase detection, hospital-grade filtered outlets, and a rugged aluminum chassis, it enhances audio-video performance and extends equipment lifespan, making it an essential upgrade for discerning professionals and audiophiles. ## 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: J’ai essayé ça sans avoir d’attentes sur mon Naim Mu-so 2 ans et ça a beaucoup amélioré le son. Une plus grande séparation, plus de basse et de clarté. Je le recommande pour le prix. Aussi bon qu’un modèle beaucoup plus dispendieux. Review: 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. ## Features - ❤️ PHASE DETECT - Phase and the ground wire connection of AC source can be detected automatically. - ❤️ OVERLOAD PROTECTION - The sockets will be powered off when total current over 15A, press RESET button to restore power supply. - ❤️ VOLTAGE PROTECTION - Its circuit detects dangerous voltage irregularities and provides the highest level of surge & spike protection. - ❤️ HEAVY DUTY DESIGN - Metal casin with thickness aluminum plates, come with 6pcs hospital grade filtered outlets and 4pcs industrial grade direct outlets. - ❤️ POWER CLEAN - It ensures that all devices connected to W-3900 receive clean & filtered power, which reduces noise and ensures better sound and picture quality from amplifier, DJ equipment, home recording, projector, TV, computer, and other electronics. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00XWL2VVK | | Amperage | 15 Amps | | Brand | WAudio | | Color | Silver | | Connector Type Used on Cable | Barrel Connector | | Customer Reviews | 4.2 4.2 out of 5 stars (537) | | Enclosure Material | Aluminum | | Form Factor | Rectangular | | Input Voltage | 125 Volts | | Item Dimensions | 45 x 14 x 9 centimeters | | Item Weight | 2.6 Kilograms | | Manufacturer | Mistral Audio | | Mfr Part Number | W-3900 | | Model Number | W-3900 | | Output Current | 1000 Amps | | Output Voltage | 125 Volts | | UPC | 889743019780 | | Unit Count | 1 Count | ## Product Details - **Brand:** WAudio - **Colour:** Silver - **Connector type:** Barrel Connector - **Item weight:** 2.6 Kilograms - **Material:** Aluminum ## Images ![AC Power Filter Power Conditioner - AC Power Purifier with Surge Protector - Image 1](https://m.media-amazon.com/images/I/61A1hPHyxoL.jpg) ## Available Options This product comes in different **Color** options. ## 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.

If you are on the fence about this product don’t be. The quality is fantastic. This power conditioner and good cables enhance the audio in your system. It is not snake oil! Filtered AC does in fact make an improvement. I would put this up against any conditioner I have seen up to and perhaps beyond the $1000.00 mark. For me it added clarity, widened the stereo field and made the silence pitch black. I ended up buying three of these. One for my headphone setup upstairs and two for my stereo in the living room. This is of great value for the money. I also added an upgraded power cable to connect it to the wall but when compared to the one that comes with this I heard no difference.
