    REFLink Asynchronous USB Converter Features

    Asynchronous USB
    With a true Asynchronous interface our Ultra Low Noise Femtosecond Master Clocks control the output jitter from the computer source. This provides the lowest noise digital source for the system DAC and unprecedented sonic transparency from any source file.

    3 stage Galvanic Isolation
    The REFLink ensures complete isolation USB born computer noise by the use of 3 stages of galvanic isolation. This insures that your audio DAC is never effected by computer based USB born noise keeping the entire dynamic range intact.

    Hybrid Distributed Power Supply
    Ensures that the Ultra Low Noise Master Clocks perform to their potential with power supply isolation and local low noise regulation right where it is needed.
