Ever dedicated to giving listeners simple and elegant tools to perfect their setup, the USB iPurifier Pro unites the features of three legendary products – the iGalvanic3.0, iSilencer, and iDefender – and forges a single, powerful new solution for combatting USB noise. Compact, comprehensive, and uncomplicated, the USB iPurifier Pro is your personal guardian against USB noise, ensuring a purer connection between you and your music.

Features

• Active Noise Cancellation
• Galvanic Isolation
• IsoGround Technology

Galvanic Guardian

Standard USB cables and devices are designed for cheap, simple transmission of power and data, but this also allows the transmission of stray currents that cause noise and jitter. Like the iGalvanic3.0 that inspired it, the USB iPurifier Pro uses digital isolator to galvanically decouple the input and output circuitry, eliminating the problematic stray currents while allowing the audio signal to pass through.

Noise, Cancelled

USB power circuitry can all too often become a lightning-rod for high frequency EMI and RFI, raising the noise floor and disrupting the clarity of the audio signal across all frequencies. Following the lead from iFi’s wildly popular iSilencer range, the USB iPurifier Pro incorporates their Active Noise Cancellation (ANC) technology into the USB power circuitry. Much like ANC headphones, the USB iPurifier Pro duplicates the unwanted noise and inverts the phase. The two signals cancel one another, leaving you with clean, noise-free USB power feeding into your audio system.

For the most dedicated purists, they have also included an external USB-C power input, allowing users to connect a low-noise 5V external power supply. When the dedicated port is in use, the circuitry receiving USB power from the source device is disabled, and only data is received, while power to both USB output ports is handled by the external power supply.

Ground Control

Modern audio setups include a wide range of devices, often powered and grounded separately. This makes it easy to introduce ground loops, and hard to identify and remove them. Drawing from iFi’s experience with the award-winning iDefender range, the USB iPurifier Pro utilises the latest iteration of their proprietary IsoGround technology to eliminate excess earth connections.

For those who need to add a ground to their setup instead, the USB iPurifier Pro also includes a 4mm grounding port, compatible with iFi’s Groundhog+ - no matter the issue, the USB iPurifier Pro has everything you need to bury ground noise for good.

Speed Without Compromise

While iFi’s focus has been to provide a wide range of noise-reducing features, they were also determined to ensure the USB iPurifier Pro never compromises on speed. The USB iPurifier Pro boasts 10 Gigabit per second data transfer speeds, ensuring that transfer and playback of even the highest resolution audio files is never impaired, and maximizing compatibility with anything you wish to connect.
