Can the Outlaw 2160 be used as a power amp for my fronts in a HT setup? Is there any guidance on the gain settings that I need to set? Also it does not appear to have a "trigger in" so any suggestions on how to switch on by connecting with my AVR? I understand a dedicated power amp will make most sense but wanted to give this a try since I moved to a 5.1 setup from a 2.1 and wanted to use by Outlaw along with my AVR.
