Description
The Heartbeat of Your High-End Digital Audio System
The LHY Audio OCK-2S represents the pinnacle of timing precision. In a digital audio system, "jitter" (timing errors) is the primary enemy of sound quality. The OCK-2S provides an incredibly stable 10.000000MHz reference signal, allowing your DACs, network switches, and streamers to synchronize with femtosecond accuracy. The result is a dramatic improvement in soundstage depth, instrumental separation, and tonal realism.
Key Technical Advancements:
-
Premium SC-CUT OCXO: The "S" version features an upgraded, hand-selected SC-CUT Oven Controlled Crystal Oscillator. Compared to standard clocks, it offers significantly lower phase noise and superior thermal stability.
-
Three Independent Outputs: Equipped with 3 BNC outputs, the OCK-2S can drive multiple devices simultaneously. Each output can be toggled between Sine Wave and Square Wave to match the requirements of your specific gear.
-
Ultra-Low Noise Power Supply: Power is everything. The OCK-2S utilizes a custom Talema transformer and a multi-stage LT3042 + PNP linear regulation system, achieving a noise floor near the theoretical limit ($<1\mu V$).
-
Flexible Impedance Matching: Each output supports independent switching between 50 Ohms and 75 Ohms, ensuring perfect compatibility with all high-end audio brands (e.g., Esoteric, TEAC, Gustard, Mutec).
-
Vibration Damping Chassis: The heavy, CNC-machined aluminum enclosure is designed to suppress mechanical micro-vibrations, which is critical for maintaining clock stability.

Discover the Highlights
-110dBc @1Hz Offset
Ultra-Low Phase Noise
The OCK-2S utilizes a custom-selected SC-cut OCXO with optimized circuitry, significantly enhancing both low-frequency saturation and high-frequency clarity. This delivers refined, detailed sound quality and a transformative auditory experience for your speaker system.
Solid. Silent. Precise.
CNC-Machined Thickened Unibody Chassis
The OCK-2S separates compartments for components with different functions to reduce interference and mechanical resonance, effectively blocking vibrations and external noise
Powerful High-Speed Rectification & Filtering
This system integrates an EMI AC filter, a UK-made Talema transformer, and High-speed rectification filtering to suppress noise and interference in the AC power supply, significantly enhancing power purity. Even during intense bass pulses, it ensures your audio system delivers powerful, precise, stable, and clean music reproduction without any compression effect.
Three-channel 3042 pure linear power supply with μV-level power output, noise close to zero.
It significantly outperforms ordinary linear power supplies, offering superior performance and delivering a DC regulated power supply with near-zero noise. High-quality power solutions of this caliber are typically considered premium in the market.
Six independent ground control switches and six independent isolation transformers.
All six output signals (square wave and sine wave) feature transformer isolation. The output GND switch can be set to either connect to or isolate from the clock’s GND, allowing precise adaptation to the complex GND handling requirements of different audio systems.
