- iFi Power Station
- We say: We have been bombarded by false claims on power supply capabilities for years. This is a breath of fresh air. It is high time a product with real engineering dedicated to Hi-Fi - at a realistic price - has become available. This product is light years ahead of the competition. Read the following, it is informative, fact-based
- Every audio system can be tainted by poor power quality – a problem that affects many of us, especially those living in towns and cities. The quality of our mains 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.
- The Power Station is constructed with advanced technology and materials. Active Noise Cancellation II coupled with additional passive filtering on each outlet eradicates noise at the highest frequencies. The result is a mains bar that delivers highly effective reduction from unwanted noise and provides a cleaner crisper picture for OLED, LED, Smart Televisions, and Projectors.
- Sonic improvements delivered by the PowerStation include greater clarity and definition, plus enhanced dynamic and spatial qualities, avoiding the apparent softening of leading edges, timing, and dynamics that can occur with lesser mains filtering products.
The PowerStation’s case is solidly constructed from dark anodised aluminium, as befits a high-quality audio/AV component. Inside, each of the six/eight mains outlets 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.
Noise in the mains 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. iFi’s Active Noise Cancellation II is effective in reducing noise consistently across the entire frequency spectrum, by approximately -40dB.
PurCopper – a form of 99.9999 per cent pure OFHC (Oxygen-Free High-Conductivity) continuous-cast copper – is used extensively for its superior conductivity. This includes heavy-gauge internal wiring with multi-layered polymer insulation, solid PurCopper busbars and the conductive elements of the AC outlets themselves. It all adds up to a level of functionality and performance that users will not obtain from other whole-system clean-power solutions without spending considerably more.
Active Noise Cancellation II
The PowerStation’s core performance–enhancing technology is Active Noise Cancellation II – the latest version of iFi’s proprietary noise-busting tech. Most power ‘conditioning’ products engage passive noise reduction through a selection of filters and regulators. Whilst this can be effective, it has inherent disadvantages compared to iFi’s active system, which uses inverse noise current to cancel out the noise in the mains signal.
The PowerStation guards the connected equipment against 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.
The PowerStation’s smart diagnostics system helps to avoid potential issues by indicating both correct polarities and whether the system has a ground/earth in place. The lack of an effective earth 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 PowerStation’s earth socket.
It only actively provides an earth/ground connection if your system needs one. iFi calls this smart diagnostic tool Intelligent Ground because it will not create a ground loop (a common cause of buzz or hum) even if the system is already earthed.
When adding extra AC iPurifiers you are taking extra steps to remove any mains noise including those added back in from the audio components. Thereby making the PowerStation setup even more effective. This gives you the best possible main platform for your system.
"PowerStation added more depth to the music, with a bigger soundstage, space between the instruments, and a clearer vocal line"
