If my reasoning is correct, would'nt the volume control for the multi-zone output act as a gain control for the headphone amp starting with a zero level and increasing to wherever I want it? Does'nt it work the same as the main volume control with zero resulting in no output to the speakers. After all the multi-zone is there to feed a second amp which in my case would be my headphone amp. Thanks for everyone's help by responding to my thread.
