hey all, I just got this box about 2 hrs ago and have a few questions.. 1st thing I noticed is that the knob for "level controller" doesn't have the same resistance as the others, it spins for eternity and kind of clicks... is this normal? 2nd thing, I also had a problem with plugging in an instrument/ mic and having it hard panned to one side... I fixed it by opening the control panel and changing the panning on analog L and R to center, is this the correct way? and lastly, has anyone else noticed that the overall headphone output is a bit on the low side? Thanks a lot.
