SMSL G1 External Master Clock – OCXO Precision Timing for HiFi Audio

The SMSL G1 is SMSL’s first external master clock, designed to bring “time back to music.” With its SC-Cut OCXO crystal oscillator, quad-channel buffered outputs, and precision power supply, the G1 delivers professional studio-level time synchronization for DACs, CD transports, and amplifiers. Built with meticulous design, the G1 ensures ultra-low jitter, nanosecond synchronization, and a stable, pure signal chain that unlocks the full acoustic potential of your HiFi system.

10 MHz Master Clock SC-Cut OCXO ±3 ppb Accuracy Phase Noise -105 dBc/Hz Quad-Channel Buffered Outputs Constant-Temperature Chamber Linear Power Supply

Key Features

  • SC-Cut OCXO Crystal Oscillator: Phase noise is -105 dBc/Hz at 1 Hz, with accuracy better than ±3 ppb—equivalent to only one second deviation every 10 years.
  • Constant-Temperature Protective Chamber: Specially designed to shield the oscillator from external heat and stabilize internal micro-temperature differences, ensuring absolute timing consistency.
  • Quad-Channel Drive: Four independent buffered 10 MHz outputs via BNC connectors, ensuring stable impedance, strong drive capability, and lossless synchronization.
  • Precision Power Supply: Imported toroidal transformer + automatic voltage switching circuit, with triple suppression and multi-stage regulation. Provides ultra-low 6 μV noise environment for OCXO and LDO circuits.
  • Compact, Minimalist Design: CNC-machined aluminum alloy chassis, heat-dissipating structure, and minimalist footprint for effortless integration into your system.
  • Perfect System Integration: Seamlessly pairs with SMSL’s flagship stack (T2 CD Transport, D2R DAC, P2 Amp) or the 200 Family Concerto system (PL200T + D200 + PA200).
