From Smartphone to Computer: UAC2.0 USB Soundcard

The DC01 uses a USB-C connector and utilizes the standard UAC2.0 USB receiver. It is compatible with most Android Smartphones and tablets on the market. It can also be connected to the Mac and Windows computers via the high-quality supplied C to A converter. This allows it to work as a USB Soundcard. With the DC01 using the standard UAC2.0 sound card chipset, Mac and Win10 computers are plug-and-play. For WinXP, Win7, and Win8 systems, please download the driver from iBasso's website. Once properly installed, it can be used as a USB soundcard.

With a Dedicated App, the DC01 Achieves 64-Step Hardware Volume

Windows 10 and Android 5.0 and above support the UAC2.0 protocol by default. However, for compatibility reasons, Android Smartphone manufacturers still use SRC on audio output. When DC01 is connected, the maximum volume is achieved by default, the software algorithm of the device is used to reduce the volume. The software algorithm can reduce the volume but cannot reduce the noise floor. Therefore, iBasso developed a UAC2.0 volume controller app to achieve 64-step hardware volume control, effectively reducing the noise floor while achieving a better audio performance.
