FA4 took two years of continuous research and development to try a new software architecture and hardware platform, plus a unique headphone driver circuit PCB6-layer immersion gold 40Z copper thickness process, which is composed of two ES9038Q2M + 7 op amps + 4 high-precision amp drivers. Balanced output CPU main frequency up to 1GHZ, MCLK clock asynchronous working mode It is well known that ES chips have high clock requirements FA4 clock signal 908.304MHZ output supports up to DSD1024, PCM32BIT/768KHZ without losing lockHZ且不失鎖,
The technology that desktop decoding may not be able to achieve is enough to prove the powerful hardware and software operation. In addition to the conventional operation settings, many practical functions have been added, such as high-speed file reading 200G file scanning only 20 seconds. Different memory Card speed compatible setting UTF8, ASCII file list sorting seamless switching Direct reading SACD/IS0, CUE files, etc. Sound details and sound field performance are better than previous models The overall operation is simple, user-friendly, easy to use and worth playing單,人性化,易用,實用,值得一玩
