iFi LAN iPURIFIER PRO Optical Isolation Ethernet Noise Filter

iFi LAN iPurifier Pro — Optical Isolation Ethernet Noise Filter

Optical Galvanic Isolation brings even greater silence to your network-connected audio system.

The iFi LAN iPurifier Pro is an ethernet noise filter with optical isolation designed for music streamers, 4K media boxes, and media streaming PCs. It helps your network device perform exactly as it was designed to—free from interference originating from routers and network switches—so you can enjoy a quieter background, improved timing, and purer sound.

Optical Isolation Brings Even Greater Silence

The LAN iPurifier Pro utilises Optical Galvanic Isolation technology to effectively isolate and eliminate electrical noise and interference emanating from the router or network switch, helping to maintain absolute silence and purity for your network-connected audio system.

How It Works

• Optical Galvanic Isolation: Converts incoming LAN signals into optical (light) signals and back again, creating complete electrical isolation between input and output.
• Jitter Elimination: Because input and output are fully isolated electrically, unwanted noise from the LAN system is stopped from passing through into the stream or DAC.
• Signal Regeneration: After isolation, active circuitry regenerates the signal by reconstructing the binary data stream, further reducing jitter and improving system timing.

Isolation, Regeneration and Elimination

Increased system noise can amplify a streamer’s jitter, reducing performance and leading to a more digitised sound that lacks richness and authenticity. The LAN iPurifier Pro helps by isolating electrical noise and interference, reducing system noise and errors from the router or network switch. By converting LAN data to optical and back again, it achieves Signal Regeneration and Jitter Elimination in one compact device.

Plug and Purify

Simple and elegant to use—no complex network setup required. With a standard LAN input and an optically isolated LAN output, connect the LAN iPurifier Pro between your router and your network device, placing it as close to the network device as possible for best results.

Maximise Performance with iPower

The LAN iPurifier Pro is powered via USB-C, leaving room for easy power upgrades. You can upgrade to iPower2 or iPowerX to enhance overall performance. iFi’s iPower2 is an ultra-quiet, ultra-clean audiophile-grade power supply featuring Active Noise Cancellation II to cancel incoming EMI and RFI, helping reduce noise and graininess. It is stated to be more than 10× quieter than most audiophile power supplies.

How Do I Use It?

• Plug the LAN iPurifier Pro between your network router/switch and your streamer or DAC/network device to help prevent jitter and EMI from reducing music quality.
• For best results, position it as close to the network device as possible.
