Thinking about getting another digital mixer.
Only real reason that I got rid of the last one was pretty much poor connection between the tablet and the mixer on a friend's unit but I recently bought a router that has better connection than the onboard router of the mixer and that is why I think that they had bad connections. The mixers worked fine for my friend when connected via ethernet to their computers but interfered with the player every time they went to play a song because they definitely used the tap delay every song.
As I said I never experienced their issues because I only used a tablet for one show and the rest of the shows I used an old laptop for my mixer. It does mean that three of my mic inputs have to be converted from xlr to quarter inch since I only have 4 xlr inputs on the mixer and the rest of the inputs are quater inch.
