Oops, I meant to say that when you use the XLR (or 1/4 " balanced) in on channels 1 and 2, the insert's return is after the pre w/ the send after the pre. The effects in in your comp needs a line level signal. Another use for the inserts is to completely bypass the pres and eq for tracking if you use an external pre (which I recommend anyway). Just take the TS cable from the pre-amp out and only push it in util you hear the first "click" Now the out from your pre bypasses the recorder's pres for a more pure sound...
