I bought a Qu SB a few weeks ago and tested it in my Studio enviroment. Unfortunately without testing the main LR Outs. Now we tried the mixer in our band and the Signal out of LR Main had a Phase Problem too (thin Sound, no bass). I will try the new Firmware but it is very dissapointing, that a new mixer has this bug. I hope that the new Firmware fix this. I got now the feeling that I bought a Smartphone…
