Hello, good morning! I have a keyboard similar to this one, PA50 Floppy version. In my case, the volume on the left side is low, both on the outputs and on the speakers themselves. However, when I use the line inputs, the volume remains normal, with plenty of power and only the native sound of the instrument has the problem. Could you please help me?

Hi. I have the same keyboard and facing a similar issue. The output is extremely low while turning on but it increases after keeping the keyboard on for a few hours.
I've sent you an email regarding this. Could you please check it. Thanks!
