I am needing to connect several sets of speakers (in several rooms) to my main receiver (6.1 by the way). I know I can get a multiroom tap which can take two inputs from the receiver with output up to 6 sets of speakers. I know this is easily done with a receiver that has A & B speakers outputs - you simply run your B speaker outputs to the multiroom tap. But what if the receiver doesn't have more than one set of speaker outputs (the B speakers)? Is there a way to do this?
