SQ-Rack
Input (SLink) PAFL selected
Observed behavior:
PEQ changes were not audible in PAFL.
PAFL mode was not touched Post Delay / AMM.
Selecting PAFL Post PEQ made changes audible.
Switching back to Post Delay / AMM afterwards → changes still audible, correct behavior.
Pls fix.
Thank you!
I am not quite sure what you are asking to be ‘fixed’.
PFL has a ‘global’ setting (on input channels at least) where you can select the ‘tapping point’ to be monitored.
If this is set for (say) post-preamp, then the tapping point is before the HPF, GATE and PEQ processing blocks.
Setting to AFL includes the entire processing chain of course.
Have you checked the block diagram for the options available to you?
On an SQ-7 (I dont have an SQ-Rack), the page is Setup > Audio > PAFL tab and there are a whole load of options (the operation of some of these settings can cause confusion if ‘played with’).

You mean PAFL was preset to ‘Post Delay/AMM’ and you haven’t been able to hear any PEQ changes yet?
I can’t recreate that yet.
What do I have to do to create this state?
I’m a big fan of the block diagram, but unfortunately, it’s not without its share of errors.
In any case, it seems that, as I actually expected, you can choose also in AFL, for example, the ‘Post Preamp’ source point and thus listen an input channel without PEQ, while this signal still follows the fader and PAN.
Ok, it gets a little weird, but I can reproduce:
Setup → Mixer Config → Role→ Reset Mixer → Standard
Change Numbers of Auxes to 12 → Apply.
Select PAFL on an Input and PEQ changes are not audible in Headphones.
RTA is also not working.
Yes, thanks to your good description, I can now actually reproduce it this way. 
Perhaps you should also report it additional to A&H Support …
I see what you mean about the block diagram for the PAFL, PFL and AFL signal flow.
The global bus is marked PAFL but the tapping point appears to be common to both PFL and AFL. However, you run into a problem now when you come to the AFL signal.
I suppose I have not noticed the AFL issue because I have always used PFL.

Hi all,
Thank you for reporting this - I’ve reproduced it here. I’ll feed it into our software team for resolution in a future firmware update.
Here is not a specific AFL issue - it’s just the same as in PFL: Under certain conditions, an incorrect source point is used.
I was referring to the block diagram discrepancy with how the AFL potentially works with the PAFL tap point.
Looking at the above post (resetting the mixer to a ‘standard’ configuration) I am not at all surprised the the Global PAFL Source changed. I don’t think this is a ‘bug’ as such. I think the effect of the ‘reset’ is not documented as to what it will do. However, performing a desk reset like this, I would expect lots of things (documented or not) to change…
Dave
Yes, the block diagram is actually incorrect.
I think you’re still misunderstanding it a bit.
It’s not about the changing of the global PAFL source point due to a reset, but rather that there are situations, no matter how they occur, where a source point is selected as ‘Post Delay/AMM’, but ‘Post Preamp’ is used instead.
If it is changing and it shouldn’t change, that is clearly a bug.

I reported this bug here some times ago.
