MTRX Studio Mic In's / Dolby Audio Bridge...

[creativecontrol]

You need to change nothing in your DADman monitor profile.

For your setup you should create a 2x INPUT paths in IO Setup which leverage AUX IO from Pro Tools Audio Bridge 32:

Speakers_9 = 7.1.2 path, to accommodate the 9 floor speaker channels + LFE
Speakers_Z = QUAD path, to accommodate the 4 height speaker channels

Outputs - same as above - but feeding out the MTRX / DigiLink outputs (to DADman) channels 1-14.

Yes, you will be able to do Speakers, Dolby Binaural and Apple Spatial all at the same time. Use a 7.1.4 Re-Render as shown in the screen grab to feed into Logic.

DAPS Input = Dolby Audio Bridge
DAPS Output = Pro Tools Audio Bridge 32
PT Output = MTRX / DigiLink
PT Monitor Input = Pro Tools Audio Bridge

Once we get wider busses in Pro Tools you won't need to make 2 paths = floor, ceilings.
