Re: Uli Behringer of The Music Group Q&A
Hi Henning (& Antoon),
Thank you for your help on this! I've just finished documenting what worked and have posted on the two other forums where I had threads in progress, so I was just coming back here to update results and thank you both. 
We used the same AES50 connection approach that you had suggested, but were also able to get the 4-port assignment for FOH. I was helped with the routing by Paul Vannatto, one of the moderators on the Music Group forum. I've got exactly what I wanted, and we were able to get 12 MON output ports and 4 FOH output ports by using the Aux in Remap. Our approach also revealed a port shift in the mapping, which is described towards the end of this post - The solution that I found is also described.
This is a bit long, but might be useful to someone... and it certainly made me happy! Almost all of this was given to me by Paul, who was most helpful throughout.
M32Cs & DL32 AES50 Connections:
M32 FOH [AES50 B] <-> [AES50 A] M32 Mon [AES50 B] <-> [AES50 A] DL32
INPUT ROUTING:
M32 Mon, Routing, home (inputs from DL32)
* Inputs 1-8 -> AES50 B1-8
* Inputs 9-16 -> AES50 B9-16
* Inputs 17-24 -> AES50 B17-24
* Inputs 25-32 -> AES50 B25-32
M32 Mon, Routing, AES50-a (transfer DL32 inputs to FOH)
* Outputs 1-8 -> AES50 B1-8
* Outputs 9-16 -> AES50 B9-16
* Outputs 17-24 -> AES50 B17-24
* Outputs 25-32 -> AES50 B25-32
M32 FOH, Routing, home (inputs from DL32 via M32 Mon)
* Inputs 1-8 -> AES50 B1-8
* Inputs 9-16 -> AES50 B9-16
* Inputs 17-24 -> AES50 B17-24
* Inputs 25-32 -> AES50 B25-32
OUTPUT ROUTING:
(This routing contains a workaround of the bank of 8 routing limitation to get 12 IEM & 4 FOH outputs)
M32 FOH, Routing, Out 1-16 (output staging of FOH)
* Output 01 -> Matrix 1 (post fader)
* Output 02 -> Matrix 2 (post fader)
* Output 03 -> Main L (post fader)
* Output 04 -> Main R (post fader)
M32 FOH, Routing, AES50-b (outputs to DL32 via M32 Mon)
* Outputs 1-8 -> Out 1-8
M32 Mon, Routing, Out 1-16 (monitor outputs 1-8)
* Output 01 -> Mixbus 01 (post fader)
* Output 02 -> Mixbus 02 (post fader)
* Output 03 -> Mixbus 03 (post fader)
* Output 04 -> Mixbus 04 (post fader)
* Output 05 -> Mixbus 05 (post fader)
* Output 06 -> Mixbus 06 (post fader)
* Output 07 -> Mixbus 07 (post fader)
* Output 08 -> Mixbus 08 (post fader)
The FOH outputs now have to be brought into the M32 Mon as inputs, then staged (using the P16 bus) to be merged with the monitor outputs 9-12, then that bank of 8 is sent to the DL32.
M32 Mon, Routing, home
* Aux In Remap -> AES50 A1-4
M32 Mon, Routing, P16 Out INITIAL ROUTING:
* 01 -> Mixbus 09 (Post Fader)
* 02 -> Mixbus 10 (Post Fader)
* 03 -> Mixbus 11 (Post Fader)
* 04 -> Mixbus 12 (Post Fader)
* 05 -> DirOut Aux 1 (IN/LC)
* 06 -> DirOut Aux 2 (IN/LC)
* 07 -> DirOut Aux 3 (IN/LC)
* 08 -> DirOut Aux 4 (IN/LC)
When we did this, the resulting physical layout of outputs was offset by one pair (We don’t know why yet):
IEM 9/10 - DL32 15/16 (I thought this would be 9/10)
IEM 11/12 - DL32 9/10 (I thought this would be 11/12)
FOH
MATRIX 1 - DL32 11 (I thought this would be 13)
MATRIX 2 - DL32 12 (I thought this would be 14)
MAIN L - DL32 13 (I thought this would be 15)
MAIN R - DL32 14 (I thought this would be 16)
So, to get the one-to-one correspondence I wanted, I did the following:
M32 Mon, Routing, P16 Out
* 01 -> DirOut Aux 3 (IN/LC) MAIN L - DL32 15
* 02 -> DirOut Aux 4 (IN/LC) MAIN R - DL32 16
* 03 -> Mixbus 09 (Post Fader) IEM 9/10 - DL32 9/10
* 04 -> Mixbus 10 (Post Fader)
* 05 -> Mixbus 11 (Post Fader) IEM 11/12 - DL32 11/12
* 06 -> Mixbus 12 (Post Fader)
* 07 -> DirOut Aux 1 (IN/LC) MATRIX 1 - DL32 13
* 08 -> DirOut Aux 2 (IN/LC) MATRIX 2 - DL32 14
This gave me what I was after as far as physical location of outputs:
IEM 9/10 - DL 9/10
IEM 11/12 - DL 11/12
Matrix 1/Matrix 2 - DL 13/14
Main L/Main R - DL 15/16
M32 Mon, Routing, AES50-b (outputs to DL32)
* Outputs 1-8 -> Out 1-8 (monitor outputs 1-8)
* Outputs 9-16 -> P16 1-8 (monitor outputs 9-12, FOH outputs 13/14 & 15/16)
Thanks again for your help!
Best regards,
Bob Charest
