Marantz SR7400 Multi-Room with Sonamp 2120T MKII

Question

I have a multi-room (outdoor speaker set) hooked up to my Marantz SR7400 driven by a Sonamp 2120T MKII. I recently moved and re-installed everything, including my outdoor speakers. The day it was first installed, the outdoor speakers worked but the Multi-Room system on the Marantz stayed on all the time--causing it to heat up. I was able to turn off the Multi-Room, but now when I turn it back on, the Sonamp won't kick on as it should--and so therefore no outdoor speakers. I believe I pressed some buttons accidently on the Marantz or the remote--and now the Sonamp doesn't get the audio signal from the CD line out and won't kick on. Do you have any suggestions?

Thanks,
