Here is what I did today.
1 calibrated all mics and pres so that once balanced balanced I could start with all input faders at -5dB.
I did this for MixLR out and Mix7&8 out.
2. I then set a DCA on the iPad Qu-Pad. I named as “MASTER” and assigned it to Mix LR and Mix 7&8.
(This is NOT PERFECT but it works so far. But I think internal routing needs to be more in depth.
Note: If you think old school, you would just assign the same signal to more busses! Ha! 
3. Rung out the feedback points at both house locations. Parametric and Graphic are way cool here.
4. Set the delay for most natural and intelligible spoken word.
I would love to have a built-in Dugan automixer in this board as I have in the 3 Yamahas I use at work!
And…BTW, for the Yamaha upright piano I installed Helpinstill piano pickups…no feedback, no crosstalk from other nearby instruments, even sound. Out of production for years he again is selling direct-only from Texas. www.helpinstill.com Just add a little Qu EQ and it’s very cool!
I have an idea!
You can actually use the PAFL bus as a delay mix. You can delay and trim PAFL in the audio setup panel. You can also patch the Alt-Out or dSnake as PAFL and get the output from there. Just make sure you don’t press any PAFL key…
And you lose the ability to PAFL…
Does Funk city use an AR stage box?
If so I think I know a different or "similar way using main (FOH XLR ) outputs to feed ST1/2/3 in and send them to one of the stereo outputs.
Of course you would need to remove any direct to the outputs.
So you still get you PFL which is vital!
PS: I have never used the ‘tape outputs’ maybe that might work?
Otherwise a new TAB page like GC suggested is one answer.
No AR Stage box
ALT Routing
The idea was this:
Assign the ALT output to be LR Prefade
Patch ALT to Stereo input 2
Raise Stereo 2 fader in mix 3
Raise Stereo 2 fader in mix 4
(This MIGHT be a mono stereo lockout on AH Qu-16?)
But it works if I patch from 2T out instead of ALT out (albeit post-fader…grrr!)
The block diagram does NOT show a LR Prefade point ONLY a L&R pre/post in the User Guide.
Maybe I just answered my own question???
Maybe there is no LR pre?? as is selectable from the ALT routing menu??
I had to leave the church as the alarm was ready to sound!XVGSXGVVXVC%C$C!
ALT OUT VOLUME KNOB! Ha. Well?.. I knew that…not
The original plan should work but NOBODY can touch that knob
or back of the church, the vestibule and the outside speaker will be altered!
Whew! what a path!
ah, yes. Probably a removable knob - or stick a small box over it?
This is why I prefer the external processor…
what about “Y” splitting (balanced XLR to TRS) the main outputs of FOH and feed those back into ST2 ?
Assign the ST2 to what ever Outputs you want ‘EXCEPT’ FOH of course?
Matrix, Matrix, Matrix
I want Matrix on QU16…just one…
or the possibility to add the stereo mix to the mixes 5/6 to 9/10 as external bus input (as on iLive)
actually 2 track out is exactly that.
I am currently using ALT from LR Pre (I may switch to LR Post)
But best would be an internal routing capability.
Thinking about matrix on QU16 - is the issue relatively limited to this “extra processing for a second output” option?
Would a suitable feature request be to select either L&R prefade or L&R as the source for one (or more) of the stereo mixes - probably disabling any other inputs, but using the relevant output processing (accepting that this will introduce a mS or so of additional delay in that feed if you use L&R, since the output processing will be done twice).
hmm, I’m wondering if it makes sense to pick the signal even before EQ. When using the EQ in LR mix for correction of one speakersystem/room and feed this into the matrix, the matrix EQ may need to countermeasure that EQ and possibly add EQ for another room…
…or the ability to switch processing order in output section (Fader-EQ-Delay, for example), to obtain a post-fader but pre-EQ tap…
just thinking loud, no idea if this makes sense in practice… 
I’m assuming that the main fader level will be relevant to both (as a delay tower), since any alternate room cam use the alt out and ignore delay…
After mixing “lots” of long narrow marquees at low volume rather than rock volume, I use the rear delayed speakers as monitors.
So in that sense I want to hear an exact duplication of the main FOH speakers
So I would be in favour of "direct Post Main Fader with the “proposed delay tab or switch”
Of course the choice of either pre/post and EQ pre post would be good.
I have always used the ALT OUT as my engineers wedge at the backs of long rooms where you can hear only ‘just hear’ the FOH however I tested in my studio here using the head phone output socket by turning off all the boxs in the control Tab and that would work ok.
Of course this is only relating to the QU16
Thanks all…good points!
The extra routing functions would surely affect the time alignment/delay compensation of the whole mixer.
All these changes affect all.
It will be VERY interesting if and when the new software brings some of these requests.
As we’re looking to add delay anyway, it hardly matters that an extra 1ms (1 foot) of delay might be introduced in the desk.
The analogue loop is inaudible anyway (though I’m sure a few of them stacked together would be noticeable)…
Where delay compensation is important is when you sum different length signal paths.
Example: LR mix to alt to st2 in to mix78 then on mix 78 you raise input fader5 vocal to give a little more
vocal to the mix78 delayed mix now that vocal from st2 is a different length path from the direct fader 5 on the
78mix. If routing in the box is implemented part of the delay compensation scheme would be to line up the similar signals.
The Latest:
Assign the ALT output to be LR (POSTFADE) Now the MAIN LR Fader controls all Mix outputs.
Patch ALT out to Stereo 2 Input.
Raise Stereo 2 fader to zero in mix 3 (pull all input faders down off)
Raise Stereo 2 fader to zero in mix 4 (pull all input faders down off)
Raise Stereo 2 fader to zero in mix 78 (pull all input faders down off)
Send -18 tone to LR
Set ALT OUT Gain Knob for zero using Qu-Pad meters mix LR, 3,4, 78 to all be zero (-18)
Set additional delays on 3 and 4 for Vestibule and Outside respectively.
The Choir and Cantor and Guitarist rehearsed. I walked the house and tweaked a bit.
All is cool now and I can begin setting “Scenes”!
Maybe they can add these??
Scenes and Softkeys are NOT on the Qu-Pad. Boo!
The mixer’s Custom Layer is not on the Qu-Pad
The Qu-Pad Custom layers are only 8 wide (16 is preferred)
