LHY Audio AS8 Pro is a reference audiophile Ethernet switch that separates high-speed network traffic from an isolated audio zone. Dual linear power paths, SC-Cut OCXO clocking, optical isolation and 10MHz clock input/output make it a central network and timing hub for complex digital audio systems. Why it stands out Two purpose-built network zones A 10G/2.5G main zone handles servers and storage while an optically isolated Gigabit zone feeds sensitive audio endpoints. Reference clock integration 10MHz BNC input and output allow the switch to receive or distribute a compatible system clock. Extensive low-noise power design Dual toroidal transformers and multiple dedicated linear regulator stages isolate critical clock and network circuits. Flexible grounding control A dedicated grounding terminal and float/ground switch help match the switch to different system grounding strategies. Best for Reference streaming systems with NAS or Roon servers Systems requiring both 2.5GbE and isolated Gigabit audio links Installations using fiber between network zones Systems sharing a compatible 10MHz master clock Not ideal for Simple single-streamer systems with basic Gigabit needs Users needing router, Wi-Fi or managed-switch software Compact desktop setups with limited equipment space EMiUZEK Buying Notes AS8 Pro is an unmanaged switch and clock hub; it does not replace a router, streamer or DAC. The isolated audio zone is Gigabit-class; connect high-bandwidth servers and NAS devices to the main zone. Clock input and output must match the receiving equipment's 10MHz requirements. Frequently asked questions Which ports should feed my streamer? Use the isolated audio-zone RJ45 or SFP port. Can it connect to a NAS at 2.5GbE? Yes, the main zone provides four 2.5GbE RJ45 ports. Does it support 10Gb fiber? The main zone includes a 10Gbps SFP/SFP+ port; the isolated SFP zone is lower speed. Is an external clock required? No. Its internal SC-Cut OCXO operates independently. Can it send its clock to another device? Yes, it includes a 10MHz BNC output for compatible equipment. Is it a managed switch? No. It is plug-and-play rather than an enterprise managed switch.

Reclaim the Purity of Your Digital Audio The LHY Audio UIP is not just a USB isolator; it is a comprehensive signal conditioning hub for serious digital audiophiles. By combining cutting-edge galvanic isolation, high-precision clocking, and laboratory-grade linear power, the UIP eliminates the digital glare, hiss, and timing errors (jitter) inherent in standard USB outputs from PCs and streamers. Key Technical Highlights: True Galvanic Isolation: Utilizing the advanced ADI ADuM4165 chip, the UIP provides up to 5700Vrms of isolation. This physically breaks the ground loop and electrical connection between your noisy computer and your sensitive DAC. OCXO + PLL Reclocking: Features a built-in SC-CUT Oven Controlled Crystal Oscillator (OCXO). Unlike standard filters, the UIP reconstructs the USB data stream with femtosecond-level precision, drastically reducing jitter for a more natural, analog-like sound. Integrated Multi-Stage Linear Power: No external "wall-wart" needed. The UIP houses a custom Talema toroidal transformer and multiple LT3042 + PNP ultra-low noise regulators ($<1\mu V$) to independently power the isolation chip, the clock, and the USB output. High-Speed Compatibility: Supports USB 2.0 High-Speed (480Mbps), ensuring seamless playback for high-resolution formats up to PCM 768kHz and Native DSD512. Master Clock Input: For the ultimate setup, the UIP includes a 10MHz BNC input, allowing you to sync it with an external master clock (like the LHY OCK-2).
