Can the Home Theatre A/V Receiver also be used to provide music to the Whole House Audio speakers?
It can be done but is not recommended. You would not be able to watch a movie in the Theatre area and listen to music in another area of the home. Extreme care needs to be taken when purchasing the receiver. You have to make certain it is powerful enough and it has an extra set of speaker out-put terminals. Most homeowners use an old stereo receiver for the whole house audio and purchase a new up-to-date Dolby Digital Receiver for Home Theatre. Having two receivers makes operation far simpler.
