IFi AC iPurifier

Smart’ thinking.

Our Intelligent Ground system ensures the AC iPurifier will not introduce a ground loop when one isn’t needed.

• Ground LoopsIn an electrical system, a Ground or Earth loop occurs when two points of an audio system both have a ground reference which causes a ‘potential voltage difference’ between them. Ground loops are a major cause of the noise, hum, and interference in audio, video, and computer systems.

No ground loops mean no annoying hum or buzz. Now, that’s music to our ears.

Many hands may light work…

And the same can be said for AC iPurifiers… The more you use, the cleaner the power.

And, you can also add them to your power strip. Why not separate your digital and analogue devices to lessen noise contamination even further?

Over-voltage Surge Protection (OSP)

The AC iPurifier has a ‘quad stack’ of Bit-Perfect DSD and DXD DACs by Burr-Brown. The ‘interleaved’ configuration means up to 8 pairs of differential signals can be used and mixed, equal to 4 pairs of signals per channel.

show Polarity and Earth detection

The LED indicators show Polarity and Earth detection. As usual, green is good, red signifies an issue.

There are four possible combinations and these can be found in a brief table in the User Manual. This tells you what the issue is and suggests how to remedy it.

This is an active not a passive product

This is an active not a passive product. As can be seen from the graph, it cancels far more noise across the frequency range than a passive product.

Active filtration is MUCH better in the lower frequencies, at -40dB. Passive filtration is only truly effective in the very top-end of the frequency range.
