Emax

Still trying to get my emax to sample!

I'd been having problems with the machine not getting an input signal (or a very weak one.) Before shipping it off for repair I pulled each of the chips inside, dusted the board and reseated them. Not too technical, but I now have a visible signal when sampling...it seems to have worked. 

When sampling I can however only see the signal in the vu mode...I can't heard anything. Should I be able to hear the audio passing from my turntable, through the emax, prior to sampling? I can only hear the signal after I've sampled, which obviously makes picking an exact spot on the record to sample a bit tricky! 

Not sure if there is a setting I've disabled, if this is yet another problem with my board, or something else.

 Any insight, as always, is appreciated greatly.
