Hi everyone. I own the md20 and love it  I currently am sending the FOH from the mixer to a driverack pa + and from the DBX to EV ELX 115ps and the QSC subs   I am seriously considering the Lm speaker and utilizing the L6 link capability. How would I set up my system with the Lm's being the tops and the QSC s as the subs?  Would I have to not use the driverack and go out via the L6 link from the M20D to the Lm line 6 link inputs and the go signal out to the subs and then set the cross over button on the Lm to match the same fixed cross over of the QSC?  I there a way to utilize he DBXat all with this set up?
