Don't you need additional wires to connect to the atmos modules to route the atmos channels from the receiver? Or do you somehow have connections from the front speakers to the add-on modules and the add-ones are able to extract the atmos channels? Are the front speakers also playing the atmos channels?
I was at Axpona and I thought the demo they had with triad speakers had an addition pair of wires to each add-on atmos speaker?
