Thanks SAAudio for the info. That was what I was using and it was turning on MA. I need it turn turn on MSA instead. I ended up using the SR7400 multi to turn it on and off. Now just trying to get the source selection to work for MSA and not MA.

Thanks for the info though. Might just have to get an RP6 to do what I want it to do but this is just a temp config until the complete Crestron system is up and running.
