School PAC application: Have recently switched from a digital Soundcraft to a QU-32. I have booth monitors plugged into ALT out, and the setings in I/O patch/Surface set to derive signal from “PAFL”. Using headphones I can listen to the prefade input to the channels. I can not listen to channels pre-fade using the booth monitors, only post fade, after I bring them up in the mix. This “listen before adding” was a capability we used extensively on the Soundcraft for setup and troubleshooting. Besides an adaptor to run the self powered booth monitors from the headphone jack, is there a way to monitor the headphone feed using the ALT out ? Another selection on the surface menu " Headphones" would do it ! Thanks for considering ---

Check your PAFL settings. Page 61 of the PDF manual. ---

Thank you Dick for the suggestion. I have tried all the settings on the PAFL screen and can not get the desired effect. When I compare what I hear in the headphones to the ALT output, while PAFL’ing a channel, they are not the same. Based on the PAFL settings, I can listen to the pre-fade signal from a channel in the headphones before adding it to the L-R mix just like I want. This same “monitor before add” capability is not coming out the ALT jacks, and that is what I am looking to do. I am believing that it is just not supported in the software. I can do what I want by using a patch cord, and running the self powered booth monitors from the headphone jack rather than the ALT, but then I loose the headphone jack for other potential uses. Appreciate any suggestions. ---

OT… Have you turned up the Alt Out pot located right by the 'phones pot? I’ll dig out my desk later today or tomorrow and see if I can replicate your situation. ---

Just ran a check and mine works fine. Re-check your settings for luck. Otherwise, save any settings to your USB stick and do a hard reset of the desk. ---

There is something weird that goes on sometimes especially I find after taking changing show data and I always run my PAFL out through ALT OUT If your desk looks similar to this do what Dick says. Hes a master Grasshopper 😑 However your Settings should look something like this as attached… and I use these desks everyday Hope this helps ---

Also may want to check “safes”, re-load your scene or zero out and start fresh new scene.
