Precautions When Using the Product
The Astell&Kern USB-C DUAL DAC Cable is compatible with most Android-based smartphones and tablet PCs, computers running Windows 10 and macOS. iOS-based devices, such as iPhones and iPads are currently not supported. Some Android devices may require adjusting certain settings to function correctly.
Due to hardware, software, and system limitations of certain supported devices, not all functions may work correctly or be available for use.
When connected to a Windows PC, the device is automatically recognized and the correct driver will be installed. A separate USB DAC Driver installation may be required for high-quality sound playback, and can be downloaded from the Support-Download section of the Astell&Kern global website.
To play DSD and high-quality PCM sound sources on a smartphone, a separate free/paid app that supports high-resolution audio playback must be installed. (When using the smartphone's own built-in player, audio may be down-sampled)
When connecting to a playback device (Android-based smartphone, tablet PC, and PC), be sure to check the volume level before connecting earphones and headphones. Some devices may automatically set the output level to maximum volume when the USB-C DUAL DAC Cable is connected. Listening to headphones or earphones at maximum volume may damage your hearing. Please verify the volume level before each use.
When connecting the USB-C DUAL DAC Cable to an Astell&Kern player and using the cable as an external DAC, the output volume will be fixed at the maximum volume setting. It is not possible to adjust the volume through the Astell&Kern player. Listening at maximum or a high volume setting may cause serious damage to your hearing. Astell&Kern, its affiliates and agencies, cannot be held liable for any damage or injuries from negligent or inappropriate use. We do not recommend using the USB-C DUAL DAC Cable with Astell&Kern players.
Firmware updates may be released periodically for stability improvements. For more information on firmware updates and to check if a firmware update is available, please visit the Support-Download section of the Astell&Kern global website.
