Using Hi-End Concept to Build USB Bluetooth Digital Audio Player
Using pure battery power supply, greatly reducing interference, a set of advanced audio system, the final and most important link is the power supply, the best power supply is the battery, which converts the alternating current into direct current and provides pure power, which is the best solution Program. The battery power supply provides enough clean power for each device, solves the problem that the sound of traditional AC power is greatly affected by the environment, and makes the sound more stable and quieter.
There are various interfaces, the output is AES / RCA coaxial / optical / HDMI(i2s), and the input method is Bluetooth / usb. AES/coaxial is independently output through digital isolation, and i2s is independently output through LVDs chip to reduce interference and make the output signal more pure. Among them, there is an i2s DIP switch on the device, you can adjust the corresponding i2s line sequence according to your own device, and you can also provide information to adjust it before leaving the factory.
Version 5.1 of QCC5125 Bluetooth reception is more stable than the previous generation CSR8675, supports LDAC, APTX-HD high-standard reception, uses high-speed buffer reception, and switches chips to ensure high-purity signal transmission. (All Android phones with Androic version higher than 8.0 can support LDAC technology, but Apple phones do not support LDAC).
The usb interface adopts the domestic Italian interface. If you have high requirements, you can contact the customer service to make up the difference and replace the original Italian interface..
