First, for the readers, let’s clarrify that there is actually only one emitter being used. It has dual 3.5mm male plugs. I didn’t know these existed. I knew that elan used to make y cables for connecting two control systems to one emitter.

This seems like one of those cases of just because you can do something doesn’t mean you should. I don’t understand why you want a Xantech connecting block if you have a real control system. Disconnect the receiver on the connecting block. The receiver on the connecting block could be picking up IR and constantly flooding the emitter.
