I have a Denon DRA-395 with a multi zone feature. In addition to the main "zone 1" it has zone 2 and zone 3 rca outputs. These zones allow the same or different program that is on in zone 1 to go to a different room. The advantage is the second and third room source, volume, etc. can be controlled from the single remote or main Denon unit. The manual says that a power amp is also needed in each room that you would feed either the zone 2 or zone 3 output signal into. I do not have a power amp but I have an extra Sony STR-DE315 that I am not using. Is there a way to use the Sony in place of the power amplifier in the second room? If so, which input of the Sony should the zone 2 outputs go to?
