I use trigger output 1 of the 990 to turn on the switched outlets of my power center. Connected to the switched outlets are a 5 channel amp and subwoofer for my main room. I was expecting the trigger output to only be active when Zone 1 was active. Nope. I just hooked up Zone 2 and when only Zone 2 is on, my amp and subwoofer in the main room also kick on. Has anyone else encountered this issue and find it annoying?
