iFi Audio - AC iPurifier - AC Power Noise Reducer

iFi Audio - AC iPurifier - AC Power Noise Reducer

The mains power supply is the ‘gasoline’ that fuels an audio system. And, whether it is clean or contaminated, it has a material impact upon the quality/enjoyment of playback.

The AC iPurifier is the latest iFi product from the ‘power products’ stable to clean-up noisy mains supplies.

It is no ordinary mains purification product. Technologically advanced, it’s an active, not a passive product so it goes above and beyond and cancels far more noise across the frequency range than other passive devices.

Latest purification product to benefit from ANC technology
Since developing Active Noise Cancellation (ANC) in-house, we have utilized it in all the relevant products from the iPower all the way up to the micro iUSB3.0.

The AC iPurifier is the latest product to have onboard ANC. As its name suggests, it ACTIVELY cancels the noise which makes it one of the power accessories, if not the only one, that actively cancels noise.

Wireless Purification System
The Wireless Purification System (WPS) is a complex circuit that reduces power line noise without audible or measured side-effects. This is important because such solutions, while attempting to curb noise, also hamper dynamics. This is not the case with the AC iPurifier.

Modular design to suppress noise
With many modern audio systems, there are typically a plethora of mains plugs. All of these add their own unwanted noise issues and pollute the local mains supply.

The design of the AC iPurifier is such that it is even more effective if several are used to ‘contain’ the same type of noisy sources.

You can insert into the AC mains wall outlet that supplies the audio system OR insert into the mains extension block for the audio system. Try both locations to discover which has the greatest impact on improved sonics.

Intelligent Ground connection
There are more than a few AC clean-up devices that add an extra Ground/Earth but only the AC iPurifier has ‘Intelligent Ground’. You can buy the optional extra 4mm ground cable to give the audio system the best possible Ground/Earth but it will ONLY actively provide a Ground/Earth (if it detects the lack of one*. It will not create a ground loop).

‘Smart Polarity and Earth’ detection
When it comes to mains AC, there are two common errors which people can make when setting up a system. The first has to do with polarity and the incorrect orientation of USA and EU type mains pins.

Intelligent Polarity automatically informs you of incorrect orientation by changing to a red LED.

The second error is the lack of a Ground/Earth.

In a system where there may or may not be a lack of a Ground/Earth, simply insert the AC iPurifier into the system and it will tell you one way or the other.

When the two LEDs light up green everything is in order!

Overvoltage Surge Protection
Last but not least, for the rare instances where there is an overvoltage spike (from a mains electricity surge or lightning strike for example), the AC iPurifier will automatically shut off and stop electricity from passing through your system. This should protect your valuable and highly-sensitive mains equipment from harm.
