  • iFi Audio DC iPurifier2

    Is underlying system noise polluting your enjoyment of music? The iFi Audio DC iPurifier2 will reduce interference in your system, often caused by noisy power supplies. Your everyday Switch Mode Power Supplies (SMPS) are very noisy. They were never really intended for audio use. The DC iPurifier2, just like its predecessor, combats unwanted noise coming from SMPS to ensure the pure sound of your audio wins through.

    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 combination is measurably more effective at eradicating noise corrupting the USB signal than devices relying solely on passive filtering.

    Noise Alchemy.

    Handles anything

    Simply place the DC iPurifier2 between the SMPS and the device you want to use. Your device could be anything from a DAC (digital-to-analogue converter) to a DAW (digital audio workstation). The DC iPurifier2 will halt unnecessary noise in its tracks.

    Super effective. Super cool.

    It’s an ultra-wide band design that is effective from 1Hz all the way up to 5GHz. Its strongest performance is in the audible range of 20Hz to 20KHz. The DC iPurifier2 handles five volts right through to 24, and comes with a variety of adapter sizes making it compatible with all power supplies – 5.5 x 2.1mm, 5 x 2.5mm, and 3.5 x 1.35mm.

    So, what’s new?

    The DC iPurifier2 uses iFi’s optimised Active Noise Cancelation2 technology based on the ingenious Thales Spectra military radar defence technology used in jet fighters. In the immortal words of Maverick from Top Gun, “Maverick going supersonic. Be there in 30 seconds!”

    The devil is in the detail

    Only top notch components are used in our tech. The details speak for themselves. Adding the DC iPurifier2 into your system will not only reduce background noise, it will bring out more definition, detail and warmth in your music.
