I am about to wire my outdoor patio and hope you can answer this question. My patio has two distinct sitting areas that I hope to put 4 speakers (2 sets of 2) in, but my AVR only has 1 zone to work with. I plan to control the amp via my wifi network. i plan to simply fork each of the red and black at the amp and make runs to the respective patio areas. Hopefully that is simple enough. However, I was thinking about putting in a volume control at one of the patio areas (the less used area). is this ok to do? my rationale for this is that usually all 4 speakers would be on simultaneously, and could be controlled generally via my phone app. but in certain instances, i might want to lower the volume to the second patio area independently. Any thoughts?
