I think I may have my problem solved and I don't know why this isn't used more often, but if you don't use the Multi Zones you can use the Multi Zone trigger with a good programable remote. I need this because I have two Panamax units one of which only needs to be on when I am using certain devices. The other Panamax is used anytime the 950 is on, which is most of the time. I wish the 950 had source triggers.
