Description
Precision Redefined: The Reference Timing Standard
The LHY Audio OCK-2P is a professional-grade 10MHz master clock generator engineered to provide the absolute reference frequency for the world's most demanding digital audio systems. By replacing the internal clocks of your DACs, CD players, and network switches with the OCK-2P’s ultra-stable signal, you eliminate the "digital grit" and restore the natural, fluid harmonics of the original recording.
Why the OCK-2P is Essential:
-
Professional Grade SC-CUT OCXO: The OCK-2P uses a hand-picked, high-specification SC-CUT Oven Controlled Crystal Oscillator. This core provides superior long-term stability and extremely low phase noise, ensuring your digital audio components operate in perfect synchronicity.
-
Triple Independent Outputs: Featuring 3 BNC outputs, the OCK-2P can synchronize three devices at once. Each output is physically isolated to prevent cross-interference.
-
Universal Compatibility: Each of the 3 outputs features its own independent toggle for 50 $\Omega$ / 75 $\Omega$ impedance and Sine Wave / Square Wave selection. This makes it compatible with everything from consumer Hi-Fi to professional studio equipment.
-
Silent Power Foundation: Noise is the enemy of precision. The OCK-2P features a high-performance Talema transformer and a multi-stage LT3042 + PNP linear regulator circuit ($<1\mu V$ noise), ensuring the OCXO operates in a perfectly clean electrical environment.
-
Premium Thermal Management: The heavy CNC aluminum chassis isn't just for shielding; it provides a stable thermal mass to help the internal oven maintain a constant temperature for the crystal, minimizing frequency drift.

Fully Upgraded Power Supply: Stronger.Cleaner.More Stable .
Two-Stage Regulation: LM350T + LT3041
The two-stage linear regulation topology further reduces noise and improves PSRR compared to the single-stage design of OCK-2S.
This ensures a cleaner and more stable power foundation for both the OCXO and the distribution circuitry.
30VA Toroidal Transformer
OCK-2P features a Multicomp 30VA transformer, doubling the power headroom compared to the 15VA design used in OCK-2S.
Greater power reserve results in:
- Improved transient response
- Lower supply impedance
- Enhanced overall stability
Ultra-Low Additive Phase Noise Clock Distribution
OCK-2P upgrades its clock distribution amplifier to an ultra-low additive phase noise design, maintaining exceptional signal integrity even with multiple outputs.
Selectable Grounding for System Optimization
OCK-2P features a dedicated grounding terminal with a selectable ground switch, allowing users to choose grounded or floating operation to best match your system.
