Can someone post a picture of their DM1801 calibration data? Or post the downloaded data?
I aquired my dm1801 without working audio out. If i blow into the mic I only hear a faint sound.
Not sure if its calibration data related.
Maybe the previous owner messed with the settings in this area after applying Opengd77.

In the menu I already set mic gain to max.

It is very unlikely that the calibration data is to blame.
Much more likely that you have a faulty microphone capsule.

Thanks for the reply and sorry for my delayed reaction.
I will consider it a hardware failure then :( and will look into it how to access the mic.capsule somehow.
