iFi Audio have consolidated their brilliant mains power technology from the iPower and iPurifier ranges into the new Power Station mains distribution block. Each piece of the Power Station is meticulously built for quality and performance. Active Noise Cancellation II technology effectively reduces noise by approximately -40dB, while the high purity PurCopper outlets and OFHC Continuous Cast Copper internal wiring ensure maximum signal/current transfer throughout the unit and it’s connected cables.
iFi’s new Power Station mains bar uses Active Noise Cancellation to deliver a class-leading, whole-system clean-power solution for high-performance audio/AV systems.
The Power Station is the latest addition to iFi’s collection of performance-enhancing audio essentials – a six/eight-way mains block (depending on region) that ensures any audio or AV system is supplied with clean, consistent electricity to unleash its full potential.
Every audio system can be tainted by poor mains quality – a problem that affects most of us, especially those living in towns and cities. The quality of our mains power is further affected by the abundance of cheap switch-mode power supplies in regular 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 raw material from which these signals are formed – the power we feed our systems – is corrupted, the negative impact on sound quality is unavoidable.
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 Power Station is the first to offer the company’s proprietary Active Noise Cancellation in a whole-system, six/eight-outlet mains solution.

Intelligent technology to tackle a universal problem
The Power Station’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 single. The way this works is not unlike the technology in noise-cancelling headphones.
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 right across the frequency spectrum, consistently reducing noise 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 an affordable mains bar that delivers a highly effective reduction of both differential mode noise (caused, for example, by typical switch-mode power supplies) and common mode noise (including interference caused by Wi-Fi and Bluetooth) from an affordable mains conditioning block.
Smart features to enhance and protect
The Power Station’s smart diagnostics system helps to avoid potential issues by indicating correct polarity and whether the system has a ground/earth in place. The lack of 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 the optional ground cable (supplied) into Power Station’s earth socket. iFi calls this circuit Intelligent Ground – this is because it will not create a ground loop (a common cause of buzz or hum) even if the system is already earthed.
The Power Station not only enhances the performance of every connected audio/AV component, but it also guards the connected equipment against spikes and surges in the mains supply. Instantaneous and repeatable protection at the highest level ensures that damage will never occur as a result of power fluctuations, providing valuable peace of mind. If the protection circuit is triggered, the Power Station will only reboot once it is absolutely safe to do so.
Specialised construction for optimum performance
The Power Station’s case is solidly constructed from aluminium, as befits a high-quality audio/AV component. Inside, each of the six/eight outlets is independently isolated within its own chamber, preventing differential mode cross-contamination.
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, solid busbars and the conductive elements of the outlets themselves. It all adds up to a level of functional performance that no other mains conditioning block under £500 can muster.
Sonic improvements delivered by the Power Station 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 products. Available from August with a choice of UK, EU and USA outlet types, it significantly raises the performance level of every connected component – a whole-system upgrade that delivers excellent value for money.
