SilentPower USB iPurifier Pro

Galvanically Isolated USB Signal Purifier with Active Noise Cancellation
Sale price$249

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.

SilentPower USB iPurifier Pro USB Noise Isolator

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.

Frequently Asked Questions

What does the SilentPower USB iPurifier Pro do?
It combines galvanic isolation, Active Noise Cancellation, and IsoGround technology to help reduce electrical noise, EMI/RFI, stray currents, and unwanted grounding issues within compatible USB connections.
Does the USB iPurifier Pro limit USB data speed?
It supports data transfer speeds up to 10Gbps, allowing high-speed USB transmission while applying its noise-reduction technologies.
Can I use an external power supply with the USB iPurifier Pro?
Yes. A dedicated USB-C 5V power input allows a compatible low-noise external power supply to power the output circuitry. When external power is used, the source device's USB power is disabled while USB data continues to pass through.
What is the power-only USB output for?
The second USB-A 3.0 output provides power without data, allowing compatible USB equipment to receive power separately from the primary power-and-data connection.
Can the USB iPurifier Pro help with ground-loop noise?
IsoGround technology is specifically designed to remove excess earth connections that can contribute to ground-loop noise, and the unit also provides a dedicated 4mm grounding port.
