8. USB DAC mode

USB DAC Mode Guide

USB DAC mode description

When the player works in USB DAC mode, the player can be regarded as a USB HD decoding receiver or as a USB sound card.
The player working in USB DAC mode supports the USB Audio Class 2.0 (UAC2) protocol, but does not support USB Audio Class 1.0 (UAC1), so the host needs to also support USB Audio Class 2.0 (UAC2).

How to enter USB DAC mode

1. From the top of the player, pull down the notification bar, select [Working Mode], and then select [USB DAC Mode].

2. Enter [Settings]->[Working Mode]->Select [USB DAC Mode] from the desktop icon.

Different host systems will have different power supply, so the USB DAC provides two working modes:

USB DAC working mode

1. USB DAC mode (charging)
   After selecting this mode, the current provided by the host is not only used to operate the player, but also charges the player. Therefore, it is recommended to select this mode in scenarios where the host power supply current is large, such as when the host is a computer.

2. USB DAC mode (not charging)
   After selecting this mode, the current provided by the host is only used for the player's operation. Therefore, it is recommended to choose this mode when the host power supply current is small, for example, when the host is a mobile phone, select this mode.

Different host systems have certain differences in their support for USB Audio Class 2.0 (UAC2). Please confirm the support status according to the corresponding system. For details, please jumphere, the following provides a brief reference:

Support status of different hosts

1. Windows
   Windows (Win7/Win8/Win10 versions before 1703) does not support the USB Audio Class 2.0 (UAC2) protocol, so you need to install the driver to use it. For driver installation, please refer tohere。
   Windows (Win10 1703 or later) begins to support the USB Audio Class 2.0 (UAC2) protocol, plug and play.
   When the computer is powered by an external power supply, it is recommended to use the USB DAC mode (charging).
   When the computer is powered by battery, it is recommended to use USB DAC mode (without charging).

2. MacOS
   MacOS itself already comes with a driver. You can use it by connecting the player to a MacOS computer via a USB cable.
   When the computer is powered by an external power supply, it is recommended to use the USB DAC mode (charging).
   When the computer is powered by battery, it is recommended to use USB DAC mode (without charging).

3. Linux distribution
   Linux's support for USB DAC is determined by the kernel. Whether the kernel of different distributions turns on the USB sound card function is uncertain. For Linux distributions that do not support USB DAC, you can compile the kernel yourself to implement the USB sound card function. Or find a third-party application to support USB DAC function.
   When the computer is powered by an external power supply, it is recommended to use the USB DAC mode (charging).
   When the computer is powered by battery, it is recommended to use USB DAC mode (without charging).

4. Android
   The Android side distinguishes between exclusive methods and non-exclusive methods.
