Geluid krakend en nauwelijks hoorbaar bij audio opname

I want to record an audio track in Logic Pro and I can hardly hear any sound, it comes from very far away and it cracks enormously, via monitoring and also in the final recording. All devices were tested separately: synths, microphone, mixing console, Scarlett Focusrite interface, they all work perfectly. I don't think it could be anything other than a setting in Logic Pro...

Can anyone help me with this?
