Questions about Denver MRD-51

With which function does this happen? Unfortunately, we have not found a solution to this problem in the operating instructions. denver.eu/media/27764/denver-mrd-51-im-en.pdf

Hi there, it works fine for me. Try changing the needle.

The Denver MRD-51 has an RCA output. If you want to connect external speakers, the speakers need a corresponding RCA input.
