Consumer grade XR1075BBE audio enhancement function

The XR1075 operates with a minimum operating voltage of 6V and a typical value of 12V. Connecting the preamp will improve the sound quality, so it is not suitable for use as a headphone amplifier, nor can it be installed behind the power amplifier for tuning (the tone must be installed in front of the power amplifier). The separate chip only gains the sound field effect and tuning function. Without amplification output. If you want to bring an amp, you need to add a booster level!

This is my first time painting this type of board, so it’s a little imperfect!

I started soldering, but I didn't expect to run into a little problem. The power of the soldering iron is small, and the large solder joints on this type of board are a bit troublesome when the heating is not done. I will need to buy a better high-power soldering iron or air gun in the future!

After welding, here's a close-up photo.

测试视频在附件，还行。现场听比录像视频回放好多了一些细节视频中没能体现。
