I just got a Signature 2.1 off ebay & Im having a problem with it. I've got everything hooked up right it seems, rca's from my HK 230 to the amp & speaker wires. I dont think I have a 12v trigger on the back of my 230 but I still cant get the amp to get out of standby mode when I run it manualy. The "signature" logo doesnt light up & all I see is the amber led light when the button is pressed in & the red light when its off. Am I missing anything here? I dont believe there are any settings in the receiver that I need to set to use a external amp? Or maybe I just got a bad amp(probably it).
