SilentPower USB iPurifier Pro
Description
The SilentPower USB iPurifier Pro is an all-in-one USB noise-reduction solution designed to provide a cleaner connection between computers, streamers, DACs, and other USB audio equipment. It combines galvanic isolation, Active Noise Cancellation, and IsoGround technology to address electrical noise, EMI/RFI, stray currents, and unwanted ground connections within a USB system.
Galvanic isolation electrically separates the input and output circuitry while allowing USB data to pass through, helping prevent stray currents from traveling between connected components. Active Noise Cancellation targets high-frequency EMI and RFI within the USB power circuitry, while IsoGround helps eliminate excess earth connections that can contribute to ground-loop noise.
With USB-C and USB-B 3.0 inputs, USB-A power/data and power-only outputs, and data speeds up to 10Gbps, the USB iPurifier Pro is designed to reduce USB-related noise without compromising high-speed data transmission. An external USB-C power input also allows the unit to be powered by a compatible low-noise 5V power supply.

Galvanic Isolation
Digital isolation galvanically separates the USB input and output circuitry, helping prevent stray electrical currents from passing between connected devices while maintaining USB data transmission.
Active Noise Cancellation
Active Noise Cancellation targets high-frequency EMI and RFI within the USB power circuitry by generating an inverted noise signal designed to cancel unwanted electrical interference.
IsoGround Technology
IsoGround technology is designed to identify and remove excess earth connections that can contribute to ground-loop noise. A dedicated 4mm grounding port also allows connection to a compatible grounding solution when an additional ground is required.
High-Speed USB Performance
The USB iPurifier Pro supports data transfer speeds up to 10Gbps, allowing it to provide its noise-reduction functions without restricting the high-speed USB connection required by compatible audio and digital equipment.
