My lockup problem has been extremely rare.... just sucks that this time cost me a valuable recording. At least the show didn’t stop.
I always check power where my bass amp and rack with dl32r is, using a cheap three prong tester for ground conditions, and then with my very old but trusty fluke for volts. I have used an ups, but only for shows with generators, as I have had more things blown up by crappy power.
I spent hours looking at options for a better mixer - even though the dl32r could use a refresh in general, and more love from the dev team (android/windows support, Little things like simple ability to change the time/date, etc) - it’s hard to beat the thing for features, size, and all.
I just can’t justify changing platforms at this time, so, I guess I will buy a new dl32r and hope they don’t release a new one after I make my purchase...
