I have a distributed speaker system throughout the house that uses Russound technology, and is fed by a Denon Receiver. Not sure if yours are the same, but my in-wall Russound volume controls also have small built in amplifiers, which amplify the signal without the requirement of an additonal amp. It just takes the signal as provided from the receiver outputs. Although I don't use my 990's Zone Two for this application (I feed speakers from my 7700), I believe it would work the same.
