My point was if you're prepared, nothing fails. (Obviously not true.) Anyway, I carried a spare when I started gigging with the DL1608 and also when I updated the software. So far, no issues affecting a gig with the Mackie. I still have my MixWiz that's for sale. (Not expecting to ever need the additional channels from that. It has always been a solid mixer.) I'm selling two of my QSC amps today. (Going towards powered speakers from now on.) Just more stuff that has never failed me. I've got some large speakers that need a new home. If I can't sell them the way they are, I'm pulling the drivers and putting them in my Kustom 250 guitar amp that I use for piano. (RCF speakers. Quite nice.)
