iFi AC iPurifier Noise Isolator

iFi

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.

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.

i.     MUCH better at -40dB and
ii.    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.
