Whole-System, Eight-Outlet AC Power Solution with Active Noise Cancellation
Every audio system can be tainted by poor AC power quality – a problem that affects many of us, especially those living in towns and cities. The quality of our household AC power is further eroded by the abundance of cheap switch-mode power supplies in typical household appliances and the sea of RFI/EMI in which we are constantly bathed. The signals that move loudspeaker drive units are electrical. If the ‘unrefined fuel’ from which these signals are formed – the power we feed our systems – is corrupted, the negative impact on sound quality is inevitable.

iFi manufactures a number of highly effective products that reduce ‘noise’ (distortion) in incoming electrical power – both directly from the mains or via USB ports. But the PowerStation is the first to offer iFi's proprietary Active Noise Cancellation in a whole-system, eight-outlet AC power solution.

Actively Cancels Noise
The iFi PowerStation actively cancels all noise. This means it is able to cancel far more noise across the whole frequency range than a passive product, even across the lower frequencies. Additional passive filters have been added on each outlet to eradicate noise from the very highest frequencies. Each outlet is independently isolated in its own chamber to prevent differential mode cross contamination with the addition of strategically placed EVA (Ethylene Vinyl Acetate) to damp vibrations.

The iFi PowerStation also uses Solid PurCopper™ Bus-Bars for power transfer, high performance PurCopper™ outlets, and heavy OFHC Continuous Cast Copper internal wiring.

Smart Diagnostics and Intelligent Ground
The PowerStation’s smart diagnostics system helps to avoid potential issues by indicating both correct polarity and whether the system has a ground/earth in place. The lack of an effective ground can cause an audible buzz or hum through the speakers, resulting from amplified low-level mains noise. This can be rectified by attaching an optional ground cable into Power Station’s ground jack. iFi calls this circuit Intelligent Ground, because it will not create a ground loop (a common cause of buzz or hum) even if the system is already grounded.

Spike and Surge Protection
The PowerStation not only enhances the performance of every connected audio/AV component, it also guards the connected equipment from spikes and surges in the mains supply. Instantaneous and repeatable protection ensures that damage will not occur as a result of power fluctuations, providing valuable peace of mind. If the protection circuit is triggered, the PowerStation will only reboot once it is absolutely safe to do so.

Actively Goes Where No Power Block Has Gone Before
The PowerStation’s core performance –enhancing technology is Active Noise Cancellation II. It is an Active and not a passive product. This enables it to achieve a far more comprehensive termination of noise across the frequency spectrum. Most power ‘conditioning’ products engage passive noise reduction through a selection of filters and regulators. While this can be effective, it has inherent disadvantages compared to our active system, which uses inverse noise current to cancel out the noise in the mains signal. The way this works is not unlike the technology in noise-cancelling headphones.

Noise in the AC supply occurs at different frequencies, depending on the cause. Passive noise reduction systems are effective at the top end of the frequency spectrum but tend to be less so at lower frequencies. In addition, passive systems need large capacitors to be truly effective, which make the best such products bulky and expensive.

The iFi Active Noise Cancellation II technology is effective in reducing noise consistently across the entire frequency spectrum, by approximately -40dB. This is coupled to additional passive filtering on each outlet to eradicate noise at the very highest frequencies – typically caused by wireless transmission systems. The result is a mains block that delivers highly effective reduction of both differential mode noise (caused by conventional switch-mode power supplies, for example) and common mode noise (including interference caused by Wi-Fi and Bluetooth).
