Reduce noise in your USB audio playback with the iFi AUDIO iPurifier3 USB Type-B Purifier. This device uses active noise cancellation to help reduce the noise from the power supply to enhance sound quality. It also employs iFi's REclock, REbalance, and REgenerate technology to minimize jitter and balance the USB data stream. It has a USB 3.1 Gen. 1 Type-B input and a USB Type-B 2.0 output.

Active Noise Cancellation2

The iPurifier3 is designed to identify noise frequency, then generate identical but opposite frequencies to help actively cancel all the incoming noise.

Three-in-One Re-Clocking

Designed for use with all downstream DACs, REclock is a three-in-one feature engineered to re-clock, regenerate, and repeat the USB audio data streaming, helping to eliminate jitter for enhanced music flow. REbalance is designed to remove the DC offset in a USB audio signal to "re-balance" it to decrease the threshold of background noise and help achieve an overall noise reduction of 40 dB on the input signal and a leveling from 100 to 5 mV on the audio band through the USB signal.

OS-CON Capacitors

These capacitors are engineered to have a low Equivalent Series Resistance (ESR), augmented noise reduction capability, enhanced frequency characteristics, and a long lifespan.

Tantalum Capacitors

These polarized electrolytic capacitors are designed to have superior frequency and stability characteristics to help provide a high volumetric efficiency.

MELF Resistors

MELF (metal electrode leadless face) resistors are engineered for enhanced accuracy, stability, reliability, and pulse load capability.

Copper-Alloy Shielding

The EMI shielding is designed to isolate devices and cables to help block RF electromagnetic radiation.

Multi-Format Support

The iPurifier3 supports PCM, DSD, and DXD audio formats.
