Recently i brought D6C and managed to fix it... mostly. There is one last problem when I record through a mic onto a tape, it also records a wierd sound(like realy low quiet buzz) that is repeated every 2 or so seconds. Has any one experienced this problem? I know the mic and the tape is good.
It sounds like a power issue. Have you tried using the mains adaptor? Because the microphone is powered from the AAx4 it could be struggling to power the mic
