Ich verwende Acrobat XI Pro 11.0.23. In einem eingescannten PDF mit überwiegend schwarzer Schrift möchte ich den Kontrast erhöhen. Ich kann dazu in den verschíedenen Menupunkten nichts finden.

There's no such option in Acrobat, it's not an image editor. You will need to edit the file in Photoshop or something like that and edit it there. You can do so directly via Tools - Content Editing - Edit Text & Images, then right-clicking the image and selecting Edit Using and then your image editor. After you edit the image and save it the PDF will automatically update with the new version.

OK. Sounds like a plan, however, it has to be done page by page, right ?

So is there some other version of Acrobat XI Pro, that is able to adjust the contrast for all pages in the document ?

No. What you can do is export all the image, batch edit them in Photoshop (for example), and then create a new PDF file from them.
