In order to be able to put six speakers: two RCA output plus two XLR output and two booth output, would this configuration be possible?
I can give it a try on Monday evening if you want and then report it back here.
I don't think you'll have any issues. IMO there's no reason to think it wouldn't be possible.
Yes, that should work. Never tried it with my S4MK3 but it definitely works with other Mixers.
Ok, thank you for responding so quickly, in the S4 MK3 manual it does not specify it, it says: xlr or rca but it does not say anything about it being a problem to use simultaneously, it is not in any diagram either, that's why my doubt.
