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.
