These cordless mics always have some base unit that collects all the mic inputs with controls for on/off (mute) and sometimes volume/gain. The output of that goes where you want.

Since this is custom you install it and then work out how to operate and if there's an issue you change setup, connections and sometimes the gear.

The biggest mistake is to try to make a system that does it all. For example if you need a video player I might not use the laptop. I might get some BluRay player to do that.
