With trickle-down technology from Abbingdon Music Research (AMR), the very latest product from iFi is the DC iPurifier; a noise-cancellation product aimed to enhance the existing, ubiquitous Switch Mode Power Supply (SMPS).

Generic SMPS designs are very noisy because they were never intended for audiophile applications.

The DC iPurifier sits in-between the SMPS and the device such as; router, DAC, set top box, media streamer, laptop or desk mixer. And with the latest Active Noise Cancellation® technology, from 5 volts all the way up to 24 volts (up to 3.5 amps) the DC iPurifier sharply reduces noise to improve the quality of the device.

Got SMPS? Just add the DC iPurifier

Generic Switch Mode Power Supply designs are noisy – but they were only intended for mainstream use so noise was never a consideration. Just insert the DC iPurifier between the existing noisy power supply and the source; noise is reduced by a factor of 316x to 100,000x.

Be it home or professional audio, this is the most simple and most effective way of improving audio performance from arguably, one of the most noisy sources in a computer audio system.

Active Noise Cancellation® derived from military radar technology

ANC-

Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation® (ANC®) audio power system.

ANC2

An enemy air defence radar will transmit at a certain frequency; when the enemy signal reaches the aircraft,
a receiver on board the aircraft will pick up the signal and a computer will analyse its base
frequency/modulations and produce an identical, but out-of-phase signal to cancel the enemy radar signal.

By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC® is the perfect ‘antidote’ for power supply noise, the bane of all audio systems.

CHARTS - DC iPurifier

Across the audible range, measured noise is improved by 316x to 100,000x or by 50dB to 100dB respectively.

Sonically, the background and inner resolution to recordings is brought to the fore and no longer hidden. Sonics are much smoother, just like how good analogue should be. Nothing comes close.


1hz to 5ghz_logo

Ultra wide-band design, effective from 1Hz to above 5GHz

iFi leaves no stone unturned; the DC iPurifier is a ground-up, ultra-wide band design.

Effective from 1Hz all the way up to 5GHz. Crucially the strongest performance is in the audible range of 20Hz to 20KHz.

Red protection LED will be lit if the input polarity is reversed (If reversed polarity, please correct).


Compatible with all power supply designs 5V-24V/3.5A/84W

The DC iPurifier handles 5v through to 24V. Takes up to 3.5A or 84W. For different types of DC barrel connectors, the DC iPurifier works with 5.5 x 2.1mm but also ships with adapters for 5.5×2.5mm and 3.5×1.35mm. These three fittings cover the gamut of DC barrel connectors.

Professional audio applications typically require a ‘centre negative’ power supply. To lower noise with the DC iPurifier, use a ‘centre positive’ power supply at the input and use a special white ‘inverter’ at the output.

iFi Audio – DC iPurifier & iUSB3.0 nano is a must see says Miyaji-Gakki!

20160326-1

The following review from Miyajj-gakki includes recording which the iFi products was involved with!

“The products which have already hit the listener of the audio system, but it is at once the beginning of the experiment in to say that than can also be used in the recording if you are variously overcome the weakness of the USB signal!……This is useful items that sound just gets better connect with would say quite roughly!……Music used in the demo is a sound source of three-piece, which was a one-shot-recording at the time……This time, the overall grain of sound is improved resolution by refreshing, it also increases the left and right of the spread or the phase has improved.”

Thank you Miyaji-Gakki and Top Wing Coporation (iFi:Japan)!

Don’t Stop Believin’ in the DC iPurifier!

20160326

“How to use iPurifier DC is easy, just connect between the DC power supply equipment and power supply adapter. This alone caused the signal of the noise signal and the reverse phase for us to remove the noise…….Husky voice of Steve Perry in the “Don’t Stop Believin” becomes smooth disappear incidental sound, will improve the overall roughness. “Waltz for Debby” is obviously an increase in the number of environmental sound echoing in the concert hall, the better the separation of each instrument. In particular, drum and base of the left channel is now divided to listen properly to bass.”

DC iPurifier: “the sound image of each instrument becomes more realistic.” says Hisaaki of Phileweb!

20160314-1

“USB-DAC, USB hub, network hub, router, such as NAS, recently, has increased audio products and peripherals that use the adapter to the power supply. In fact, I think that the fact that you are using the adapter of the switching system that most of them are always issues a huge noise, many also already you know…….iPurifier DC of iFI audio to introduce this time…….This machine, it can be said that the breakthrough product that solves the switching adapter specific problem. If used in the form sandwiched between the adapter and the equipment you are using now, because changing the appearance to the usual power adapter is “audio grade”…….Here also raise the S / N of audibility, the sound image of each instrument becomes more realistic.”

Thank you Hisaaki Hijikata and Phileweb!

Liam of Computeraudiophile.com taken back by the DC iPurifier!

“For those unfamiliar with the Acoustic Revive RR-888 it is a Schumann Resonance generator. It is not connected physically to the equipment, merely plugged in within the room. Image below…..Using a linear PSU is a well known/accepted way to improve it’s performance…..I was curious to try and establish if it was the beefier nature of the Keces and/or that it was simply cleaner than the suppliedsmps was responsible for the benefit, and the DC iPurifier was just the job for that…..I was quite taken aback at the affect putting the DC iPurifier in the line from the Keces PSU had. For example, listening to Greek Orthodox Russian chant the bass lead’s voice became fuller. Now he was singing from his chest with an open mouth, a big strong sonorous voice, rather than previously with a more closed mouth and more like from the back of his throat. The texture, harmony and body of the choir was much improved. The guitar on Nils Lofgren’s live album became sweeter on the opening track. Listening to piano the transformation was quite startling. The notes were richer, and the whole sound was fuller. The dynamic power of the piano was more evident. Bass extension is improved overall.”

Thanks Liam!

Phileweb blogs about the DC iPurifier!

2016219-12

iFI-Audio “iPurifier DC” get back in the ranking. mini item called iFI-Audio “iPurifier DC” is, raise the power from the switching type DC adapter to the audio grade. That so-called “switching system compact power adapter” by sandwiching it between the equipment body, something that is possible to reduce the power supply noise. The “Active Noise Cancellation” in the case he military radar technology has been diverted, somehow terrible likely.”

Thank you Phileweb!
