How to use

Connect the adapter to a computer USB port; the operating system should recognize it as a USB Audio Class 2.0 device. Select the adapter as the audio output device in the computer’s audio settings. Use the appropriate cable to connect the adapter’s digital coaxial, Toslink, or I2S output to the input of an external DAC, receiver, or audio interface. Ensure the external device is configured to accept the chosen digital input and set the sample rate in the player or system to match the desired 24-bit/192 kHz output.

Recommendations

For best performance, use high-quality coaxial or Toslink cables and set the playback software or system audio sample rate to match the target device. Verify compatibility of the receiving device with I2S if using that interface.
