LHY Audio AS8 Pro

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.

Comparison: Which Reference Network Switch Is Right for You?

AS8 Pro is the choice for multi-zone networking and system-clock distribution; AS6 suits a smaller Gigabit chain, while English Electric 16Switch focuses on additional copper ports without fiber zones or clock integration.
