Any mention of “us,” “we,” “our,” etc is by iFi Audio, not AV One.
An All-In-One Trinity of Noise Reduction.
We’ve long been at the tip of the spear in developing ways to silence USB noise – one of our earliest successes in the field was the iGalvanic3.0, and among enthusiasts it has remained one of our most pined-for legacy products.
The USB iPurifier Pro is our spiritual successor to the iGalvanic3.0, but it’s also so much more. 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.
Key Features Explained
Galvanic Isolation
The USB iPurifier Pro galvanically isolates the input and output circuitry, eliminating the stray currents that cause noise and jitter.
Active Noise Cancellation
The USB iPurifier Pro uses Active Noise Cancellation technology to eliminate EMI and RFI, purifying noisy power.
IsoGround Technology
The USB iPurifier Pro uses IsoGround technology to intelligently and safely remove excess earth connections.
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 our wildly popular iSilencer range, the USB iPurifier Pro incorporates our 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, we also include 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 our experience with the award-winning iDefender range, the USB iPurifier Pro utilises the latest iteration of our 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 our Groundhog+ – no matter the issue, the USB iPurifier Pro has everything you need to bury ground noise for good.
Speed without Compromise
While our focus has been to provide a wide range of noise-reducing features, we 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 maximising compatibility with anything you wish to connect.
