Hi. I cannot get the auto feature on the 409W digital subwoofer to work. When i set the 'Auto Feature' to the 'On' position (Down Position), the subwoofer will always stay on (the blue led on the sub is lit) even if the Denon Reciever is swithed off. Even if the Denon Reciever has been swtiched off over night, the blue led is still lit. When i set the 'Auto Feature' to the 'Off' position (UP Position), the subwoofer will turn off after a while or so, (the blue led on the sub is off), however, when i power on the Denon Reciever the sub will not power on untill i switch the 'Auto Feature' back to the 'On' position (Down Position). Please Help. I don't like leaving things on for no reason when it is not being used. Thanks In Advance.
