Does anyone know for preouts on my 7013 what is the setting to get the same signal from main left and right to come out of surrounds? I have plugged them in and set the amp for surrounds in speaker set up but nothing comes out of them regardless of my playback mode. I’m doing something wrong and probably simple. But will this give me the same signal as left right mains or is it a surround signal? Sorry for being naive or stupid. I have read the manual over and over and it doesn’t give much detail and I can’t get Marantz on the phone since covid. They must have one person handing North America
