I am satisfied with the sound and build quality. The functionality for channels 1-4 is great and very versatile, compare to cheaper counterparts.
What dissapointed me was the lack of "mono" input feaure on channels 5/6 and 7/8. If I have channel 1-4 full and have another mono source I can only plug it to channel 9/10, which has one of the two jacks "mono" so basically splitting the mono signal to both left and right. The problem is that the 9/10 is shared with USB in/out so if I want to plug in PC or phone for recording or backing track/click track playback via USB, I cannnot use this channel anymore. I have created mono splitter so I can plug in to channels 5/6 or 7/8, but it is extra effort in both creating the cable (found difficult to find ready to use one) and keeping it at hand....only because the manufacturer omitted such a basic function that even cheaper mixers have.
I am dissapointed that the 5/6, 7/8 and 9/10 are unbalanced connections - again some cheaper mixers have such functions.
The main switch could have been on the top, rather than at the back, which makes it sometimes tricky to find, especially if placed in some sort of shelf with limited access to the back of the device.
