Special Features

  • 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.
  • Discrete LNRD: How to solve the noise problem from USB power? The DX1's answer is the Discrete LNRD circuit (low noise reference driver). The Discrete LNRD circuit filters out the noise and interference of USB 5V power and provides stable and clean power supply of ultra-low noise reference level for DX1. With this technology, the noise of DAC part is lower than 2.0uV, and the noise of AMP part is lower than1 .0uV. Even high sensitive IEMs will not bothered by noise.
  • 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.
