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:

HiBy R4 User Manual | HiBy WiKi
https://guide.hiby.com/en/docs/products/audio_player/hiby_r4/guide
17/20
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).

18/20
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.

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
When the player is working in Bluetooth reception mode, you can think of the player
as a Bluetooth HD decoding receiver or as a Bluetooth headset (after connecting the
headset). The player supports decoders such as LDAC/AAC/SBC, so the host side
also needs to support encoders such as LDAC/AAC/SBC. Android phones generally
