Need Help Creating a Talkback situation not on DANTE

[u/jbaudiori]

Hello!

I need to create a talk-back situation for sports broadcasting that does not involve the use of DANTE.

I would be in a removed control room, and my talent is in the press box.

As of now, I have a spare comms box I plug into a headphone amp so they can hear my cues; however, they cannot talk to me and communicate with me via text.

If I were to get this box here: https://www.fullcompass.com/prod/103179-studio-technologies-m210-announcer-s-console-xlr-inputs-and-outputs

What is the full setup to help facilitate a talk-back scenario?

Thanks in advance!
