The iPurifier3 delivers a comprehensive USB signal quality solution. From common electrical, protocol, data to EMI/RFI issues, the iPurifier3 solves them all, in one, thumb-sized design.

The iPurifier3 re-equalises unbalanced USB signals for an improved audio data stream and re-clocks, re-generates and repeates the USB audio data stream. The iPurifier3 simultaneously reduces the USB power supply noise by more than 100 times.

Features

• REclock, REgenerate repeats the USB signal, eliminates USB jitter, frame and packet noise and restores USB signal integrity
• REbalance corrects USB signal balance and impedance mismatch
• Upgraded Active Noise Cancellation (ANC) military-grade circuit, which now has a wider operation band and reduces USB port audio band noise even further
• New OS-CON and Tantalum capacitors for extra power filtering and smoothing
• New high-precision MELF resistors for improved accuracy and stability
• New gold-plated copper-alloy shielding to reduce EMI interference
• USB Audio Class 2.0 (supports all formats)

Active Noise Cancellation® drawn from military radar technology

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. It is now a cornerstone of the ever-improving iFi USB audio technology, looking for new products to feature ANCand ANC+. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an on board system to cancel out 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 USB audio. ANC measured, noise drops by 100 times or 40dB in comparison to the Common Noise Filter. Sonically, the background and inner resolution to recordings is enhanced several levels.

REclock reclock/regenerate/repeat the signal

Re-clocking is beneficial to audio. REclock is a 3-in-1 feature that re-clocks/re-generates/repeats USB audio datastream. For any and every downstream DAC, REclock technology eliminates jitter. Music flows better, is cleaner, deeper and tauter, just like the real thing.

REbalance rectify the unbalanced signal

A core element of the original iPurifiers success was REbalance which has naturally been carried over to the iPurifier 2. By removing the DC offset and re-balancing the USB audio signal, it is now perfectly balanced. As it purifies the USB audio data stream, this means noise is significantly reduced:
