Hello,
I thank you for your answer,
On Reaper, I indicated channel 3 for the DI signal output but I have no sounds. I connected an XLR cable to Mix Output 3
I can’t find the solution to send the signal through Mix Output 3
You will see attached the photo of the cable connection and the routing on the QU16
Then I use the QU serial driver and it works well
Regards,
Valentin
