Built around an ultra-precision OCXO (Oven-Controlled Crystal Oscillator) and SMSL's proprietary CK-03 clock processing circuit, the G1 delivers a 10 MHz reference signal with exceptionally low phase noise, transforming the timing accuracy — and consequently the soundstage depth, image focus, and high-frequency clarity — of any compatible digital component.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eOCXO: The Gold Standard in Clock Stability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAt the heart of the G1 is a laboratory-grade OCXO module. Unlike standard TCXO (Temperature-Compensated) clocks, an oven-controlled oscillator maintains its crystal at a constant elevated temperature inside a miniature oven, virtually eliminating frequency drift caused by ambient temperature fluctuations. The result is short-term and long-term frequency stability that no conventional clock can match — critical for preserving the precise timing relationships that define stereo imaging and transient accuracy.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCK-03 Clock Processing Circuit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSMSL's self-developed CK-03 circuit provides ultra-low-jitter clock distribution with multiple galvanically isolated output stages. By slashing phase noise and preventing ground-loop contamination between connected devices, the CK-03 ensures that the pristine 10 MHz reference generated by the OCXO reaches your DAC or CD transport completely intact.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQuad 10 MHz Outputs with Independent Isolation\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe G1 features two 50-ohm BNC clock outputs, each galvanically isolated from one another. This allows you to simultaneously clock up to four separate devices — for example, a DAC and a CD transport — without cross-contamination. Both outputs deliver a clean 10 MHz sine wave with industry-standard 50-ohm impedance, making the G1 compatible with a wide range of high-end digital components from SMSL and other manufacturers.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCNC-Unibody chassis with Advanced Vibration Control\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe G1 is housed in a precision CNC-machined aluminum unibody that minimizes internal resonance while providing effective EMI shielding. A suspension-based internal mounting system combined with silicone damping feet further isolates the sensitive OCXO module from environmental vibration — because at this level of timing precision, even microphonic interference matters.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIntuitive Status Display\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA clear front-panel display shows real-time clock status, output activity, and warm-up progress.
