To quieter and beyond.

Come on, heal the noise!

Got underlying noise in your system? An irritating noise that you can’t explain? Sonics grainy? It could be as simple as your power supply.

Upgrade to the iFi iPower2 to feed your system’s circuits with ultra-quiet, ultra-clean audiophile-grade power.

Noise-Cancellation culture.

The new iPower2 boasts improved components and a thicker gauge of wiring to deliver improved output/input noise suppression.

And with Active Noise Cancellation II to cancel out all incoming EMI and RFI noise, you’ll never feel powerless against noise and graininess again.

It is more than 10 times quieter than most audiophile power supplies.

iPower2 the people!

It comes in 5V, 9V, 12V or 15V. Each voltage is individually available for your particular region and includes a reverse polarity adapter for centre pin negative products.

Add the iPower2 into your system to bring life back to your music. Discover lost detail today.

Ifi Audio iPower Plug

Plug in, turn on, and chill out.

iPower2 comes with a set of 5 five differently-sized adapters to suit some 73% of DC plugs including a reverse polarity (white plug) for professional audio products that require a centre negative feed.

Flashdance?

If you’re into photography the iPower2 can also solve the annoying issue of flickering LED lights.

With a constant current and voltage, the iPower2 will ensure that the power supplied to your LED system will remain stable no matter what fluctuations occur in the AC feed from your wall socket.

iPower2 can be used in conjunction with DC iPurifier2

Dream Team.

iFi products are modular. The iPower2 & DC iPurifier2 is like Batman and Robin — a barnstorming combo that enables the customer to try throughout the system to see where they improve the sound the most.

It’s official. It’s highly recommended by iFi!

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.

It works with virtually any DC powered device and comes in 5, 9, 12 and 15 volts.

Just check the correct voltage and away you go. Clean, audiophile grade power.

Reviews

Excellent low noise power supply.

Excellent product. Perfect for high quality audio equipment. No hum at all as expected. A little expensive but worth it.

EMI (Electromagnetic Interference)

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.

RFI (Radio-frequency interference)

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.

Switch Mode Power Supplies (SMPS)

A switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. It transfers power from a DC or AC source to DC loads, such as a personal computer, while converting voltage and current characteristics.

Switch-mode power supplies are widely used because of the advantages they offer in terms of size, weight, cost, efficiency and overall performance. They are in themselves noisy and were not designed with audio in mind.

Active Noise Cancellation

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.
