It would be great to have the option to choose pre or post fader for the headphone outputs. This is mainly so I can monitor the Main LR output in the headphones even when the fader is low or muted. I have the workaround which is to create a stereo mix that emulates the Main LR mix so that I’m able to have the Main LR master down or muted and be monitoring the Stereo mix but it means I have to sacrifice 2 of my output channels.
you can still use the listen button on the main LR, which should do the trick.. worth a try if that passes full signal even when the fader is down..
As far as I know (and judging by the block diagram), mixes can unfortunately generally only be listen after-fader, which is why the desire for a PFL option for mixes on the CQ has frequently been voiced here.
