You can choose where the Qu-Drive records from as described in the user guide here – https://www.allen-heath.com/content/uploads/2023/06/Qu-Mixer-Reference-Guide-AP9372_10.pdf#page=54&zoom=auto,-214,844
If using insert send, you will record a completely clean signal from each channel. If using direct out, it will follow your direct out settings (see pg38 and refer to the block diagrams at the end of the guide).
The direct out can include some or all of the processing depending on your source point, FX returns (reverbs, delays and modulation) need to be patched separately if you want to record these alongside the individual channels.
