AK4493S: The DX1 uses newest sub-filagship AK4493S chips of AKM'S VELVET Sound technology. AK4493S is an upgraded version of the previous AK4493. Plug and play: turn your PC into a HIFI source DX1 has a wide range of compatibility: Windows 10, Windows 11, MAC, Linux, I0S, Android can be plug and play. Only for Windows ASIO applications, you need to install the driver and set it up. The USB hardware is based on XMOS XU208 and Thesycon custom driver (applicable to Windows, other systems are free of driver), which is stable and reliable. No adapter required: Like other USB device, the DX1 does not require an additional adapter for power supply. Only one USB cable can complete the power supply and data transmission. Powerful output in a small hummingbird size : In such a tiny size, DX1 can provide a maximum output of 280mW x2 without additional power supply. Excellent enough for serving as a pure DAC: DX1 has Line out with fixed volume, which can be used as a pure DAC with headphone amplifiers, power amplifiers and other equipment.
