Audio/Video from Mixer/Switcher to AJA IOXT

In my production room, I want to get audio and video from my audio mixer and switcher to my AJA IOXT device. I will then feed that audio/video from the AJA IOXT, to my MacPro which will have the Wirecast software to stream to Facebook Live and Youtube Live.
Which BM device would you recommend to get the audio/video from my audio mixer/switcher to my AJA IOXT device?
BTW, I checked into the Web Presenter, but it appears there are some issues/limitations with that device.

If there is another workflow that would work, I'm open for suggestions.

Thanks.

which video mixer do you use? most bm mixers already have an analog or digital audio in. you probably don't need anything else.

The video production switcher is a Ross Carbonite 1-A. HD-SDI video output.

You need an SDI audio embedder of some kind.
