SilentPower LAN iPurifier Pro – Ethernet Noise Filter with Optical Galvanic Isolation

The SilentPower LAN iPurifier Pro is designed for audiophiles and professional AV installers looking to eliminate network-transmitted noise, jitter and interference. By sitting between your router or switch and media streamer, DAC or network audio device, it uses optical galvanic isolation and signal regeneration to deliver a cleaner, more stable data stream with improved timing and reduced noise.

Key Features

• Optical galvanic isolation: Converts incoming LAN signals into optical light, isolating the output electrically and preventing noise from the LAN system entering your audio chain.
• Signal regeneration and jitter elimination: Actively corrects errors and restores the digital signal to minimize timing errors in the downstream audio device.
• Gigabit Ethernet support: Supports 1000/100/10 Mbps speeds and IEEE 802.3x standard for transparent data throughput.
• Ultra-low noise DC-DC power supply: Designed for clean power delivery to the unit to maintain high signal integrity.
• Plug-and-play simplicity: One RJ45 input, one RJ45 output, powered via USB-C 5 V/1 A — no complex installation required.

Customer Benefits

Even in high-end audio systems, network noise or jitter can degrade digital stream integrity before it reaches your DAC or streamer. The LAN iPurifier Pro acts as a “cleaner” link by removing interference from the network zone and restoring signal accuracy. Whether you’re streaming hi-res music or working with a dedicated streamer, it helps maintain clarity, timing accuracy and dynamic fidelity in your system.
