ifi Audio DC iPurifier 2 Filter AC Adapter 5V-24V / 3.5A / 84W

iFi Audio DC iPurifier2

active noise suppressor for switching power supply (SMPS)

This accessory is placed between an electronic device and a DC adapter. Its role is to clean the sound naturally present in the overall electrical system to eliminate much of the audible preventable errors in the final sound reproduction. It can be mounted on any type of electronic device powered by SMPS in the string, be it a digital player, DAC or an amplifier. All equipment and all the elements that follow will benefit from a more defined signal. A great improvement for reducing the noise and gain precision in order to highlight the qualities of an audio system.

Second generation of noise canceling iFi Audio

This is the second version of iPurifier by iFi Audio. This second model further refines the machine's hardware capabilities to offer ever more effective removal of unwanted noise.

Its function is to smooth and filter the sound artifacts generated by the modulation of pulse length produced by switching power supplies. It is expected to apply a reduction factor of 316 times to 100 000 times. This core application induces a significant improvement in his at all levels of the chain using a SMPS (Switch). Whether naturally a critical element that DAC, a digital / CD / network or amplifier,

As with its first generation, the design incorporates iPurifier ANC technology (Supression active noise), directly inspired by the radar technology - especially the Spectra system of Thales.

Precision electronic components

To operate a specific filtering supply noise, the iPurifier operates a wide range of electronic components of high quality and carefully selected for this application:
there are capacitors Panasonic SP-Cap Polymer Aluminum, high-precision MELF resistors, custom AOP high-speed / ultra-low noise.

There is also a shield designed from a copper alloy developed to block the best Electromagnetic interference specific for this use.

The housing itself is designed in a shielded alumunium aircraft grade so that the signal does not recapte new interference once filtered.

Active filtering precision

Removal is made possible by the identification of noise and applying a reverse phase signal.

If iPurifier filter any unwanted frequencies over a wide band 1Hz - 5GHZ, the deletion is of course centered on 20Hz-20Khz band to purify as much as possible the audible frequencies and improve the sound quality on all power supply devices SMPS.

surprenant et efficace
monté sur une boc upc et un modem wifi upc. j ai gardé les alim a découpage d origine car les remplacer aurais couté cher. Deux de ses petit purifier ont eu d excellent résultats .image plus dynamique précise et le bruit a bc reculé. Le son que je récupère sur un bloc HDMI extracteur audio a gagner en précision dynamique et clarté, grave plus propre et ample.. l autre monté sur le modem a apporté les mêmes résultats avec une bande passante plus large vus les améliorations d écoute sur mon streamer.. pour le prix sais du bon rqp. conseillé vivement avant l achet d alimentations dédiées .
