Where the OCK-1S Sits in the LHY Clock Range

The OCK-1S is designed as the entry point into precision master clocking, delivering a stable 10MHz reference that significantly improves timing accuracy over standard internal clocks.

It introduces the core benefits of external clocking—lower jitter, improved coherence, and cleaner signal reproduction—without the complexity of higher-end systems.

As systems become more resolving, higher-tier models build on this foundation with improved phase noise performance, more advanced power design, and greater system-wide synchronisation.

Is the OCK-1S Right for Your System?

The OCK-1S is ideal if you are entering the world of external clocking and want a clear, immediate improvement in timing, clarity, and overall musical flow.

If your system includes multiple clock-capable components or you are aiming for reference-level performance, stepping up to the OCK-2S or OCK-2P will deliver further gains in precision, stability, and system-wide coherence.
