C47 Passthru Function

[microbus13]

I made some changes so my system was down for a while. When I set everything back up I had problems with the Passthru function on my Mcintosh C47 which is connected to a Marantz SR7012. After working on this for most of the morning I finally got it to work. Passthru came on amplifiers came on but no audio. Finally got it to work by setting the Output 1 to unswitched. But now if I turn on the AVR first everything comes on but no audio. If I turn the C47 on first and then the AVR it works. It seams the Output 1 doesn't come on when I turn the AVR first. Don't remember if this is how it worked before or not.
