    Yinlvmei W1 windows10 player dual AK4499 USB DAC AK4499*2 HIFI player


    W1 innovatively runs the windows10 system, the advanced instruction set of the intel processor, cooperates with professional playback software, and uses the ASIO audio channel to obtain the best sound quality. This is one of the main reasons for using win, and the 7-inch screen size In order to take into account the touch experience and the design of replaceable batteries, the dual 4499 full firepower requires a larger volume to achieve. The system part and the decoding amp part are separately powered, and each is powered by a separate battery, and the charging uses one Charging interface, W1 has 3 charging modes, direct Type-C body charging, independent charging from the battery (C port supports 3A, DC port supports 6A charging), base charging. W1 has reserved a base extension. In the future, it can be used with a base to extend a desktop amp or power amplifier. In addition, the body is equipped with 3 TF card slots, each of which supports 1TB expansion, and 2 full-size USB ports for more Multiple rich peripheral expansion.
