    Product Highlights

    The Alpha USB is an asynchronous High Speed USB Audio 2.0 to digital audio interface designed to provide the highest possible audio quality from computer and music server audio sources.

     

    The Alpha USB has a USB Audio 2.0 Standard input and switch selected digital audio output signal type, either coaxial SPDIF using a BNC connector or balanced AES using an XLR connector. Sampling rates up to 192 kHz and word lengths up to 24 bit are supported.  

     

    Great care was taken in the design of the Alpha USB to isolate the noisy computer/USB environment from the digital audio output. The USB receiver and processing are powered by the computer, while the output master clocks and line drivers are powered by a separate isolated linear power supply. There is no DC connection and also a high degree of capacitive and inductive isolation between the USB input and the digital audio output.

     

    Two key factors combine to achieve the excellent audio performance of the Alpha USB; the unprecedented degree of electrical isolation between the USB input connection and the digital audio output and the very low noise/low jitter performance of the individually tested audio output master clocks.
