LHY Audio OCK-2P — Decision Profile
L2 Decision Profile · documentation + editorial assessment
Quick verdict
A reference-clock distributor for exact 10 MHz-compatible receivers
Avoid if: Arbitrary word-clock frequencies, waveform switching on every socket or guaranteed audible improvement
Evidence checked: 2026-10-17. Manufacturer documentation; no independent SoundPath Lab listening, measurement, compatibility or firmware retest.
System conditions
Match output waveform, impedance, receiver level limits and mains SKU; keep specified protective earth and avoid improvised ground lifting
Documented specifications
| Item | Specification and conditions |
|---|---|
| Outputs | 10 MHz OCXO, six BNC outputs: three sine and three square |
| Impedance/level | Each waveform group defaults to two50-ohm and one75-ohm outputs; vendor50-ohm sine2.8 Vpp/square2 Vpp claims |
| Warmup/power | 15 min basic/60 min full warmup claimed;110–120 or220–240 V SKU, about5 W stabilized |
Limits and source qualifications
Phase-noise, stability, receiver lock and audible gains untested; keep stated vendor units/conditions
Alternatives by need
C18 uses four square-wave outputs in configurable groups; a receiving U18 still requires correct REF/input setup
Keep or upgrade
Keep a working system that already meets these requirements. Consider a change only when the documented connection, control or system role solves a specific unmet need; no measured sound-quality upgrade is claimed.
Evidence, support and reassessment
Review scope
Exact-model primary specification and connection sections cited below were reviewed. Source claims and editorial system-fit reasoning are distinct from independent listening, measurement, compatibility or firmware tests; none were added.
Actual sound, under-load output, room/ear fit, latency and long-term reliability remain untested. Existing scores, Builder qualification and owner/test records were not reassessed.
Firmware and regional support
Local stock, authorized sales, transaction prices and long-term support duration are not established by this documentation review. Dated regional announcements apply only to their stated territory and terms. Existing dated price and owner evidence is retained.
No installed firmware version or issue resolution was retested. Follow the exact-model official support workflow.
Reassess when evidence changes
Reassess on verified hardware or firmware changes, clarification of a source conflict, material support/compatibility changes, or accepted independent testing.
No new six-month ownership evidence was added; existing owner and issue records remain unchanged.
