Model: 306019 UPC: 5060738783205 Item: 177291

Product Information

The multi-talented power conditioner will clean up your dirty mains power and make your music sound clearer.

Active aggression

The AC iPurifier benefits from an Active Noise Cancellation (ANC) system, developed in-house and now used across the entire iPower range from the iFi iPower to the micro iUSB3.0. It ACTIVELY cancels noise making it one of the, if not the only, power accessory to have ACTIVE rather than passive noise cancellation.

No side effects

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

Intelligent Polarity detector

When used with USA and EU type mains plugs, its Intelligent Polarity feature will automatically tell you whether you’ve got them plugged in the right way for whichever country you’re in. A green LED indicates that you have; a red LED means you haven’t.

Intelligent Ground/Earth

If you’re not sure if your audio set up has a Ground/Earth, simply plug the AC iPurifier into the system and it will tell you one way or the other. A green LED means 'Yes'; a red one means 'No'. The AC iPurifier will ONLY actively provide a Ground/Earth if it detects the lack of one. This avoids creating a ground loop. Always look for two green LEDs to know everything is in order!

Stay safe from surges

For the rare instances where there is an overvoltage spike (eg a mains electricity surge or lightning strike), 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.
