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.
