I have a Denon AVR 1804 and a Mirage SUB. Both new. The sub will not "wake up" out of stanby mode. I am not sure if it is receiving the signal from the receiver. I have the cord going in the right direction(arrow towards the sub) and i am fairly confident i have it in the right slot. i have tried unpluging it and then plugging it in again, to see if it would recognize the signal then. it has only worked when i first turned the whole system on to make sure everything was connected before moving the furniture back.
