Today I set my PT10 to record from QU16 USB B, My surprise is that some channels preamp (3,6,7,8,9,10,12,13) have stopped working, without signal in Q16. I have reviewed the pach and are all local channels. I have turned off the QU16, USB cable unplugged and on again without connecting the USB B and those entries still doesn’t work. Never has given me problems the Q16! Really strange. I have not tried AR2412 sources
I do a reset? I have v1.7
need help soon. Thank you!
Sounds like you need the v1.7.1 firmware update.
There were some issues with channels not working after the v1.7 update.
It’s mentioned in quite a few posts on the forum

you are right! I readed that issue but I didn’t realize that fixed were v1.7.1, I thought that solution was in v1.7 because always I use by AR preamps, and never has a problem with v1.7
Thanks so much robbocurry!
