8. How to Use the USB DAC Function on the DISC (USB Sound Card)？

The USB DAC function allows the DISC to decode audio signals from a computer or mobile phone.

Follow the steps below:

1.Go to Settings, select Working Mode, and then choose USB DAC Mode.

2.Connect the DISC to your computer using a USB data cable or to your phone using an OTG cable. The connection is successful when the DISC's USB DAC interface displays "Connected".

3.Once connected, simply play audio normally on your computer or phone to use the function.

4.If the USB connection is not recognized properly, try unplugging and re-plugging the USB cable. Alternatively, exit USB DAC Mode on the DISC, then re-enter the mode and reconnect the USB cable.

Note: Some mobile phones require you to enable the OTG function in their settings before it can be used. Connecting in USB DAC Mode will charge the DISC, consuming power from the computer or phone. Some phones may have insufficient power supply capability and may not work properly with this function.
