iFi PowerStation

iFi Audio - PowerStation - Award-winning power rail with active noise reduction

All Hi-Fi systems are affected by the power quality from the socket, which is degraded by the many household appliances, routers, TV boxes connected to our mains and the large amount of RFI/EMI around us. All this noise significantly degrades the sound quality, and this is where the PowerStation comes into play. This power rail is the first product from iFi Audio to feature their proprietary active noise cancellation in a six power outlet rail, and the result is so significant it might be the best money you've ever spent. At least that's what Head-Fi thinks:

" Both the PowerStation and the DC blocker are highly recommended without any reservations and honestly everyone should start improving from the mains power as this is the driving force of every music system. Best money ever spent. " - Head-Fi, Laskis Petrros 2021.

Highlights:

• Improves clarity and definition
• More controlled and defined bass
• Finer articulation
• Better dynamics
• Active Noise Cancellation II actively removes all incoming noise
• PurCopper provides superior conductivity
• Polarity and ground detector
• Intelligent Ground system, which is only activated if the system needs it.
• Wireless Purfication System reduces line noise without negative side effects.
• Over-voltage Surge Protection protects the system against overvoltage.

Intelligent technology to tackle a universal problem

Most power strips are based on a passive noise reduction that takes place through a combination of filters and regulators. But this technology has some inherent disadvantages that iFi's active system does not have. The iFi PowerStation uses a reversed noise current (opposite phase) which cancels noise in the current, and this technology has a lot in common with the way it works with the one used for noise suppression in headphones.

Another disadvantage of many passive solutions is that the noise in the mains supply is different depending on the frequency, and this makes them ineffective in the area that is most important - the lower and audible frequencies. The passive ones work best in the upper frequencies that are outside the audible range, and at the same time they need large capacitors to be really effective, which makes them both expensive and large.

Active Noise Cancellation II - technology from the military

iFi's solution, on the other hand, is a technology they call Active Noise Cancellation II, and it reduces effective noise by approx. -40db over the ENTIRE frequency range. This is therefore a significant improvement compared to the passive solutions, but the PowerStation goes one step further. They have coupled a passive filtering on each power outlet, which eliminates the noise at the very highest frequencies typically caused by wireless transmission systems. The result is a power rail that delivers a measurable and audible reduction of both the network noise caused by conventional switch-mode power supplies and noise in general such as interference from Wi-Fi and Bluetooth.

The PowerStation is so effective at reducing the noise from the mains that it didn't take long for the entire Hi-Fi world to notice the rail's qualities. Within a short time it has been voted Product of the Year in tests, received the best recommendations and much more.
