Berkeley Audio Design Alpha USB Interface

The Alpha USB acts as a bridge between your computer or music streamer and your DAC. It takes the noisy, jitter-prone USB signal from your source and converts it into a clean, high-precision AES/EBU or S/PDIF signal, which helps your DAC perform at its absolute best.

Yes, it is compatible with Apple, Windows, and Linux operating systems. Since it uses a standard USB 2.0 asynchronous connection, it should integrate seamlessly with any standard audio streamer or computer acting as a music server.

It does. The Alpha USB supports high-resolution audio playback up to 192 kHz and 24-bit depth, ensuring you can play your high-fidelity music files without downsampling or loss of quality.

No, you must select one output at a time. The device features selectable outputs, allowing you to choose between the balanced AES/EBU (XLR) or the coaxial S/PDIF (BNC) connection depending on what your DAC requires.

The enhanced mass and vibration isolation of the enclosure are critical for reducing mechanical interference. By minimizing external vibrations, the unit maintains better time-domain coherence, which results in a more stable, realistic, and immersive soundstage.

While it utilizes the USB connection, it is designed to work with an external power supply to ensure the cleanest possible signal path. This separation of power helps isolate the sensitive audio circuitry from the electrical noise typically found on computer USB buses.
