Description
Total Galvanic Isolation for Your Audio Network
The LHY Audio FMC is a professional-grade Fiber Media Converter designed specifically for high-end audio streaming. While standard IT-grade converters are powered by noisy switching supplies and imprecise clocks, the LHY FMC re-engineers the process to ensure your digital music remains free from electrical interference and jitter inherent in copper Ethernet cables.
Key Benefits
-
Ultimate Noise Isolation: The optical fiber interface physically blocks electrical noise from routers and power supplies, preventing interference from entering your sensitive audio chain.
-
Pristine Signal Integrity: By eliminating high-frequency noise, the FMC provides a much cleaner and more stable digital signal to your DAC.
-
Audible Sound Improvement: Experience a blacker background, reduced digital harshness, and significantly enhanced micro-detail in your music.
Key Technical Highlights
SC-CUT OCXO Reclocking
The LHY FMC features a high-quality SC-CUT Oven Controlled Crystal Oscillator supported by ultra-low noise PLL circuitry. This system re-clocks the Ethernet data stream with laboratory precision, drastically reducing jitter for improved rhythmic timing and soundstage focus.
Master-Grade Linear Power Supply
Power purity is paramount. The FMC is built with a high-quality encapsulated Talema transformer, UK RIFA RFI suppression capacitors, and a high-speed rectifier. The multi-stage uV-class linear regulator provides power with a noise floor close to zero.
Professional Connectivity & External Clocking
Equipped with one isolated Gigabit RJ-45 port and one SFP port. For the ultimate performance, the 10MHz BNC input allows you to synchronize the conversion process with an external master clock (like the LHY OCK series).
Premium CNC Construction
Housed in a solid CNC aluminum block chassis, the unit provides superior EMI/RFI shielding and excellent thermal stability for the internal OCXO.

Why Use LHY FMC?
In a typical Hi-Fi system, the router and home network are significant sources of high-frequency noise. By using a pair of FMCs (or one FMC and one SFP-equipped switch), you convert the electrical signal into light. Since light cannot carry electrical noise, your streamer receives a 100% isolated data stream, dramatically improving clarity and background silence.
