LHY AS8-Pro Audio-grade Network Switch

The LHY Audio AS8-Pro is a flagship-grade network switch specifically designed by LHY Audio for streaming audio scenarios. Unlike traditional network switches, this product is meticulously engineered to meet the requirements of Hi-End audio systems. It includes ultra-low noise linear power supply, reference clock system, 10G/2.5G data zone, 1G audio isolated zone, all focused on delivering the cleanest possible signal to your music streamers, music core or bridge, NAS, Media Servers and Smart TV, simultaneously optimising the performance of each device.

The internal single-mode fiber with optoelectronic isolation links the 2.5G main and 1G audio zones, ensuring an exceptionally pure digital streaming network. It boasts an SC-cut OCXO (-110dBc close-in phase noise) paired with a PLL clock chip, delivering highly accurate synchronous clocking across both zones. Clock I/O ports are included for future enhancements. Power is supplied by dual 50VA Talema toroidal transformers alongside multi-channel μV-level linear DC supplies. The unit is CNC-machined from solid aviation aluminum to minimize resonance and strengthen structural integrity, with circuit isolation to eliminate interference.
