The LHY Audio OCK-2S is a high-precision master clock with ultra-low phase noise, designed to minimize sampling errors on high-resolution streams. This clock features six independent 10MHz 50/75Ω outputs on BNC connectors, including three sine-wave and three square-wave outputs. Based on a high-performance OCXO oscillator, it significantly improves the performance of any Hi-Fi system.
Inside, you'll find quality components, including a linear power supply delivering a clean, pure signal with EMI filter, Talema 15VA transformer and high-speed rectification filter. The crystal oscillator is powered by three LT3042 + PNP voltage regulators, guaranteeing a high level of precision.
