the Paradigm manual doesn't seem to address this, so thought I'd check and see if anyone who has one knows. the PDR-10 is supposed to have auto shut-off. when I turn off my amp, the amber LED on the front of the sub stays on. I didn't know if this light is supposed to indicate "power-on" or just that it's plugged into the wall. if it's the former, I'm guessing my sub isn't auto detecting when to shut itself off. thanks.
