hi, i've just signed up to the forum after a quick google search on this very problem and i was wondering if it got solved? i have exactly the same desk and the same problem (i think). when recording from my mix outputs the signal is extremely low, however its fine if i record from my auxillaries jack outputs the problem seems to be the XLR group outputs and my main Mix L/R XLR outputs.if someone could help me out that'd be great!
cheers
