iFi Audio AC iPurifier Active Noise Filter

iFi Audio AC iPurifier Active Noise Filter

PLEASE NOTE: For UK customers, this item is shipped with an adapter for use with UK 3 pin sockets.

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.

This chart compares the AC iPurifier (green line), which is ACTIVE, versus generic mains filters (red line) which are typically passive.

The effective noise reduction difference is as different as night and day.

• MUCH better at -40dB
• Effective across the frequency range. A passive purifier filters only in the very top-end of the frequency range.

Every audio system benefits

The AC iPurifier was designed to be used in ANY mains powered audio system. It is particularly effective at dealing with modern audio systems that have an abundance of generic and varied power supplies (see next section for a more detailed, technical explanation).

Where extension blocks are used, the AC iPurifier can be used to isolate certain types of power supplies for the maximum noise reduction.

Features

• Active Noise Cancellation (ANC) - Military technology, most advanced noise-cancellation available.
• Wireless Purification System - Complex circuit that significantly reduces power-line noise without audible or visible side-effects.
• Ground/Earth connection diagnostic - Detection of missing Ground/Earth.
• Polarity connection diagnostic - Detection of polarity fault.
• Audio Earth connection - This adds a solid Ground/Earth with ground-loop prevention circuit built-in.
• Overvoltage Surge Protection - Auto-recovery.

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 supress 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 a 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 (below) 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.
