I've been using my 55-02 for quite a few years now, and mostly in active mode. However, I've come to prefer the sound of passive basses, and I like the way my lakland sounds in passive mode. The problem is that the volume decreases by about 50% in passive mode. I understand that active mode is supposed to be a little louder, but such a large difference doesn't seem right and forces me to make large adjustmens on all my levels. Does anyone know how I can make the passive mode louder?
