I am trying to use my iPhone to play backing tracks in to my QC (for practice at home, not for live performance)
In order to do this I am using a Lightning to USB OTG cable.
When this is connected I can hear the iPhone audio through the headphone out on the QC, or if I plug in to my FRFR using Out 1/2 (XLR) I can also hear the iPhone audio.
However I usually connect my QC to my FRFR using standard TS cables (the FRFR is a Powercab so has 2-way XLR / TS inout jacks)
When I do this however I get no iPhone sound from the QC.
Is it possible to get the USB audio via the Out 3/4, and if not can anyone explain why? I have looked at the ‘Info’ windows on the I/O USB settings page but don’t really understand what they’re telling me (for example this pic, below…)
