When I put my MZ-N1 in ManualREC to control the input volume manually, the volume numbers go up or down normally, but the volume bars indicate the volume actually didn't change.
And when testing by changing the volume in the middle of recording and listening to the result it's apparent the record volume didn't change. This happens with both the mic input and the line input. Auto REC still seems to work normally and the volume control still works normally for playback. Nothing got overvoltaged that I know of. Is it fixable? Thanks.
