no headphone jack. but i did listen through headphones and had the same
problem.


How did you listen via headphones w/o a jack? Didja hook 'em up to the line
level outs?
Might help to know the model unit we're talking about. Most analog
keyboards I'm familiar with don't have built-in speaker drivers, but yours
could.
