Thank you for the suggestion, would that mean that I am going from Microphone Level out of the external preamp and into a Line Level input? I’m not sure that this would work in terms of signal / gain staging? I know the SQ is designed as a Live mixer first and foremost, but I use it as my studio interface with an AB168 stage box, so I have TONS of inputs and outputs, but I also want to use my external preamp (Focusrite ISA Two) and external compressor (ART Pro VLA II). But the SQ does not have 1/4″ INSERTS for external analog gear, only XLR mic preamps and 2 Line Level inputs for keyboards etc..
If there no way to do this.. that’s fine, I just need to know conclusively.
