Whatever your set-up, digital, analogue or both, the PowerStation will ensure your system receives super quiet mains.
The iFi PowerStation is for everyone who likes their audio interference free.
It comes in 4 variatons – UK, EU and AU with 6 individual sockets and USA/JAPAN with 8.
Put a stop to RFI or EMI noise and enjoy pain-free audio – all from one solid, snazzy dark anodised aluminium power block.
The PowerStation uses iFi’s Active Noise Cancelation II to ACTIVELY eliminates noise across the frequency range, even across the lower frequencies.
Each outlet has added passive filters to also eradicate noise from the very highest frequencies.
Each outlet is independently isolated in its own chamber to prevent cross-contamination, with the addition of vibration-damping EVA (ethylene-vinyl acetate).
We use PurCopper – a form of 99.9999 per cent pure OFHC (oxygen-free high-conductivity) continuous-cast copper – for its superior conductivity.
The PowerStation has inbuilt earth/ground and polarity detection.
No earth/ground can lead to annoying buzzes and hums – the scourge of audio.
We’ve added a 4mm banana socket to the PowerStation so a grounding cable can be used to create a ground/earth when one isn’t present.
Bingo, the sound is gone.
And the PowerStation is smart. The supplementary ground/earth connection will NOT introduce a ground loop EVEN if the system is already earthed.
More than one earth would also create a ground loop leading to more buzzing and humming and we don’t want that.
Polarity detection is vital if you don’t want to hamper the quality of your audio mains. With the PowerStation, this is built-in.
And never fear, max. 30,000A @ 1,000V/10uS surge protection is also here. If it detects a power surge or a mains short, the PowerStation will shut down, protecting your downstream equipment from peril.
The PowerStation doesn’t forget where it came from – the original AC iPurifier.
You can still use your original AC iPurifier with the PowerStation – use them to separate your digital and analogue devices for even less noise contamination.
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.

PurCopper – a form of 99.9999 per cent pure OFHC (oxygen-free high-conductivity) continuous-cast copper – is used extensively for its superior conductivity.
This includes 13 AWG, heavy-gauge internal wiring with multi-layered polymer insulation, solid PurCopper busbars and the conductive elements of the outlets themselves.
Our Wireless Purification System (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.
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.
The Over-voltage Surge Protection (OSP) is an auto detection and cut-off circuit.
Should it detect an excessive power surge or short in the mains electricity it will automatically cut off. If this issue persists, it will not reboot and will protect your equipment from harm.
It is effective to max. 30,000A @ 1,000V/10uS.
Our Intelligent Ground is a smart diagnostic tool. It will only actively provide an earth/ground connection if your system needs one. It will NOT create a ground loop if the system is already earthed/grounded.
You can use AC iPurifiers in the PowerStation.
The more AC iPurifiers you use, the cleaner the overall power. If the AC iPurifier is placed in the middle of the PowerStation it will also act as a noise shield. Noise is reduced, isolated and confined to the respective left/right sections of the AC iPurifier.
Use it to separate your analogue and digital devices.
Based on military tech, our improved Active Noise Cancellation II® actively cancels all incoming noise.
It does this in a similar way to active noise-cancelling headphones – it generates a signal identical to that of the incoming electrical noise but in the opposite phase, actively cancelling it out. This is highly effective at removing low- and mid-frequency noise, while passive insulating filters deal with higher frequency interference. This combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.

“The PowerStation is solidly built! It has Active Noise Cancellation! It’s also going to protect your system investment, for the price of this device, all the benefits it has, it’s amazing!
The PowerStation provides tremendous silence that my system has never given me before!”
Thanks to Fernando for this review of the PowerStation. Glad you loved it.
The iFi PowerStation aided by an iFi DC blocker is an excellent and really effective solution to kill mains noise and greatly improve your listening experience.
Product is truly perfect. sound is greatly improved, while balance is not changed. with powercord it is fine. no noise. sublime.
“iFi produce some lovely kit, and the PowerStation is no exception. Normally ‘conditioners’ add to the sound; after all, they are basically a tone control. The PowerStation was different. It left me engaging in more of the music, with noticeably tighter bass, greater definition and dynamic control.”
Thorsten Lösch, the busy developer of iFi Audio, surprises us again and again with ingenious solutions on the subject of HiFi. And because more and more electronic users put more and more loads on the power grid, it would be a miracle if Lösch didn’t have some ideas ready here too. One of them is the iFi PowerStation power strip, which of course is anything but a “normal” power strip …

Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.
Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.
A busbar is simply a conductor through which current flows.
EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.
In simple terms, polarity refers to the way a signal flows.
Audio signals generally flow one way, like DC current, and have positive polarity. Inverting the polarity can have a negative impact on sound and equipment.
Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.
Top tip: just don’t add water.
