I hope its okay to ask a question in english. I will also use google translate to translate it to chinese, hopefully you can understand.
我希望可以用英语提问。 我也将使用谷歌翻译将其翻译成中文，希望你能理解。

The line-input is not the same volume as the Bluetooth volume (bluetooth is much louder). I want to match these, so I must increase the gain of the analog input.
线路输入与蓝牙音量不同（蓝牙声音更大）。 我想匹配这些，所以我必须增加模拟输入的增益。

These are the important settings:
这些是重要的设置：



How can you change this? The configuration tool only shows 'Gain for line' (analog gain?). If I increase it to 12dB it starts to clip, 9dB is still okay.
You cant change the settings of the pre-amplifier, only 'on' or 'off'.
你怎么能改变这个？ 配置工具仅显示“线路增益”（模拟增益？）。 如果我将它增加到12dB它开始剪辑，9dB仍然没问题。
您无法更改前置放大器的设置，只能“打开”或“关闭”。

Just because I do not speak your language, does not mean I have bad intentions.
I am a student and want to start my own company. I designed a circuit board but I had a problem.
I asked it in two languages and provided pictures, is there anything wrong?

仅仅因为我不会说你的语言，并不代表我有不好的意图。
我是一名学生，想要创办自己的公司。 我设计了一块电路板，但我遇到了问题。
我用两种语言问它并提供图片，有什么不对吗？
