I used this solution in big events, when there was a large drum set, 5 other percussions, bass guitar, choir, 3 singers, 4 keyboards, 2 violins 1 flute, 1 oboe, 2 sitars, 1 derbuka, etc. on stage, and I needed 40 channels. On the digital stage box I patched MIX5-6, 7-8, and 9-10 from the QU-24 to the 3 stereo inputs of QU-16, so I could make 3 groups for the 11 channel drum set, the other percussions, and the choir. The others were connected to QU-16, so I could use all the MIXes of the QU-16 for monitor mixing. The main L-R went to the sound processors and L-RAY systems.
On the screens of the four 10″ tablets on the flight case show the signals of the channels (QU-YOU software), the 12″ tablets on the sides runs the Mixing Station QU android software, one for the QU-24, one for the QU-16, and the a real time sound spectrum analyzer, named Spectroid.
I am happy to help, just ask, and I try to answer.
