Is the AMP Out connection on back or the denon 5800 a 12V? If yes i think it use 1/8" mini plug, how can i connect or covert this plug to barewire 12V trigger in the on the amp (how to find about after covert to barewire which is positive and which is negative)? can i trigger two amp with just one ampout on the 5800? Any other methods that can trigger the amp to turn on when the 5800 is turn on? thanks for your help!
