That mic gain adjustment is in fact a post scaling by above factors (x0.5, x1.0, x1.5, x2.0) , of each captured mic voice data . Then ,that adjustment should be only used,to make mic gain fine tuning of the non distorted voice . But if the captured data is already distorted , due to too much mic sensitivity , or to close mic-mouth distance, or too loud voice , the ADC saturation , should be addressed by other means (ALC or Boost adjustment (*1) , or increasing mic-mounth cms distance , or reducing the voice loudness.)

If you want to know the audio codec IC of your device , you do not need to dissassembly the boards, just go to the "debug" -> peripherals menu , and you will see which peripheral device, you can explore, looking its register map values. In the audio block icon , you will see the audio codec IC name , mounted on your Portapack board : AK4951 or WM8731.
