LHY OCK-2P Platinum Edition Reference Master Clock Generator
Taxes & Shipping Included
The LHY OCK-2P Platinum Edition elevates master clock technology through meticulous engineering advances that surpass its predecessor. This reference-grade generator delivers superior time-base precision, refined power delivery, and optimized mechanical construction to enhance micro-dynamics and spatial imaging. Experience redefined performance standards in external audio clock design, where every refinement contributes to deeper musical resolution and acoustic clarity.
Ultra-Low Phase Noise Performance
OCK-2P employs a carefully selected, high-grade OCXO, delivering a significant improvement in critical close-in phase noise performance:
- –115 dBc @1Hz
- –140 dBc @10Hz
- More stable soundstage
- Improved image focus
- Enhanced micro-detail retrieval
- Darker, more controlled background
Fully Upgraded Power Supply
- 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 and Enhanced overall stability
Features
- Machined from a single block of aluminum, the chassis adopts a refined five-chamber isolation architecture.
- Each compartment is physically separated to minimize electromagnetic and mechanical interference, ensuring a cleaner power environment and a more stable signal path.
- OCK-2P introduces an Independent Thermos Chamber, providing a more stable and controlled thermal environment for the OCXO.
- An integrated OCXO warm-up status LED visually indicates when the oscillator has reached optimal operating conditions.
- Three sine wave and three square wave outputs (50Ω/75Ω BNC connectors) for versatile connectivity
- Fully Upgraded Power Supply with 30VA Toroidal Transformer
- OCK-2P upgrades its clock distribution amplifier to an ultra-low additive phase noise design, maintaining exceptional signal integrity even with multiple outputs.
- 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.
