8. USB DAC mode

USB DAC Mode Guidelines

USB DAC mode description

When the player is working in USB DAC mode, you can think of the player as a USB HD decoding receiver or as a USB sound card. The player works 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 side also needs to support USB Audio Class 2.0 (UAC2).

How to enter USB DAC mode

1. From the top of the player, drop down on the notification bar, select [Work Mode], and then select [USB DAC Mode].

2. From the desktop icon to enter [Settings]-》[Work Mode]-》Select [USB DAC Mode].

Different host systems will have different power supply, so USB DACs offer 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 work and use the player, but also to charge the player. Therefore, it is recommended to choose 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 charged) After selecting this mode, the current provided by the host is only used to work for the player. Therefore, it is recommended to select this mode in scenarios where the host power supply current is small. For example, when the host is a mobile phone, select this mode.

There are certain differences in the support of USB Audio Class 2.0 (UAC2) for different host systems. Please confirm the support according to the corresponding system. Please jump to the details.Here, the following provides a brief reference:

Support situation of different hosts

1. Windows Windows (Win7/Win8/Win10 1703 previous version) does not support the USB Audio Class 2.0 (UAC2) protocol, so drivers are required to be installed to use. Please refer to the driver installation.Here。
   Windows (Win10 1703 later) begins to support USB Audio Class 2.0 (UAC2) protocol, plug and play. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

2. MacOS MacOS itself already comes with a driver, and you can connect the player to the MacOS computer via a USB cable. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

3. Linux distribution Linux's USB DAC support is determined by the kernel. Whether the kernel of different distributions is turned on USB sound card functions is uncertain. For Linux distributions of unsupported USB DACs, you can compile the kernel to implement USB sound card functions by yourself. Or find a third-party app to support USB DAC functionality. When the computer uses an external power supply, it is recommended to use USB DAC mode (charging). When the computer is powered by a battery, it is recommended to use USB DAC mode (not charged).

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

Android non-exclusive Just plug the USB decoder (such as HiBy FC4/HiBy FC6) into the USB port of your phone and use it. If you insert it, you can download HiBy Music and try the exclusive mode of HiBy Music. Otherwise, the phone will not support it. Please contact the mobile phone manufacturer to confirm.

Exclusive Android use Download, install HiByMusic. Enter HiByMusic. Swipe right to open the settings options -> Settings -> Click HiByMusic exclusive USB output, open the exclusive output. Insert the USB decoder (such as HiBy FC4/HiBy FC6) directly into the phone. The phone will pop up "Allow SeaByMusic to access HiBy FC4" and click Allow.

It is recommended to use USB DAC mode (not charged) to save battery power on your phone or tablet.

1. iOS iOS itself already comes with a driver, and you can connect the player to iPhone/iPad via a USB cable. It is recommended to use USB DAC mode (not charged) to save battery power on your phone or tablet.

2. Game console So far, XBOX/PS/Switch and other game consoles only support USB Audio Class 1.0 (UAC1), so the player's USB DAC function cannot be used through the game console.

9. Bluetooth Receive Mode

Bluetooth Receive Mode Guide

Bluetooth Receive Mode Description
