Thinking about adding an external amp to my Onkyo 797. It has a 12V trigger, but it says zone 2 on it, so I am confused, do you all turn your seprate amps on manually, walking over to it and turning it on? I noticed the 2802 and 3802 do not have 12V triggers, how do you turn your amps on? I guess I really don't have a choice unless I can figure out that zone 2 tigger on my 797 before I buy the amp. Any help...how do you do it?
