Absolute Turd I have owned many columns from EV and Bose, all with their own control app. Needless to say I was amazed that the app from QSC would not connect with either of my IPhones, and wouldn’t connect with neither Macs or IPad. After trying to pair devices with the speaker multiple times, I finally pulled out an old mixer to save the day. I will be returning my QSCs before the next gig
