Hi All, I'm confused about how to drive my multi zone system. First here is what I have working backwards: Niles ceiling speakers Niles impedance matching wall volume dials Rotel rmb-1048 8 channel amp (with input level adjustments) Marantz SR5006 AVR with zone 2 I'm inexperienced with this type of set up because I've mostly used plug and play type devices. What I don't understand is exactly what is supposed to happen when connecting the receiver with the multizone amp. With the zone 2 out connected to the line in on the amp I got sound but the master volume on the receiver seems to have no effect on the volume coming out of the speakers. The input level adjustments certainly do but these are a real pain since you have to use a screwdriver to make the adjustment. Am I wrong to think the receiver should have an effect on the volume? I thought about just maxing the wall volume dials and input level adjustments and then turning down the wall dials but that doesn't make sense to not have a central volume control. What am I missing?
