C24 talktack question

[Raggi]

HI.
I have a C24 with Pro-tools 12.4 (vanilla) and it's working great. Also using Focusrite Liquid Saffire 56 with two OctoPres MK2 Dynamic.
Also hooked up a Behringer Powerplay P-I (interface) og P-M (monitor) and this is working great too.
The Powerplay P-I are feed with 16 channels from the OctoPres and this is working fine.
NOW, how do I get the Talkback working on my C24 out to the P-I and P-M?
I saw that there was a Talkback Slate output, but I don't know what this does.
Could I take a line from this into one on the P-I ?

Yes, take the TB slate out of the C/24 and plug it right into channel 16 of the PI brain and use channel 16 as the dedicated TB for the personal mixers. I use this system and works great.

This worked perfect. I can't adjust the volume on the talkback via the volum knob, and that is really not needed cause I can adjust via the Powerplay.
How can I adjust it?

you are welcomed! You can adjust the output of the TB from the C/24 via a knob on the monitor section IIRC.
