I got a Zoom H4n a few months ago and absolutely love it for recording jams. However, I recently tried using it as a recording interface, and ran into a problem. Plugging straight in, like you're supposed to be able to do, peaks the circuit to the point of slightly distorting the signal. I tried adjusting the input gain as you would during a live recording, but as far as I can tell, you cannot do this while using it as an audio interface. I've tried with a passive strat guitar, passive Yamaha Attitude and active EBMM Sub 5 string. In ever case it seems to have this problem. Anybody know what I'm doing wrong?
