Common questions about manuals, registration, and support for this brand.
Many FX-AUDIO DACs are plug-and-play for Windows 10/11 and macOS. However, for older operating systems or specific high-resolution playback, you may need to download XMOS drivers from the manufacturer's website.
Ensure the device is powered off and the tubes have cooled down. Gently rock the tube back and forth while pulling upward to remove it. Align the pins of the replacement tube (commonly 6J1 or 5654) carefully with the socket and press down firmly.
Always use the power adapter provided with your unit or a replacement with the exact matching voltage and amperage (commonly 12V DC). Using an incorrect voltage can damage the internal components.
Check that the input selector switch is set to the correct source (USB, Optical, or Coaxial) and that your computer's audio output settings are configured to use the external DAC device.
