LHY Audio offers us their AS8 Pro network switch. The switch includes 6 RJ45 Ethernet ports, 2 SFP fibre optic ports and an input and output connected to the 10MHz OCXO clock. Everything is housed in an elegant anodised aluminium case machined from a single piece of material to limit resonance, and designed to separate data processing, audio signal processing, the internal clock and the power supply stage.
The AS8 Pro deploys two 50VA transformers for a regulated linear power supply coupled with an RFI suppression filter. Once transformed, the current passes through a low-drop multi-stage voltage regulator and voltage rectifier to ensure the cleanest possible power supply.
In terms of signal processing, the LHY Audio AS8 Pro offers 6 RJ45 ports, two of which are digitally isolated, and two optical SFP ports, one of which is also digitally isolated. But that's not all: the AS8 Pro has a 10MHz OCXO clock at its heart, itself connected to a BNC input and output. You can use this network switch as a master clock to synchronise other external sources or simply resynchronise the input signal. Finally, the OCXO clock is coupled to a PLL phase-locked loop.
