I bought mine before self-powered subs had a signal sensing circuit. The switch to turn it on/off is in the back where you can't find it, so I have just left it on all these years.
Not really making any point, just that I was looking at its green LED and trying to figure out when I bought it, and realized that it had been on a really long time. Also, that I'm really lazy and won't search for the off switch.

LOL! Not that it matters now, but there are a couple ways to have it "switched".
1) You could either plug it into a switched outlet on your receiver (if it has one).
2) Use a "Monster Power" strip with delayed outlets on it.
3) There are other power strips with audio sensing capabilities in them.
Again - Not that it matters, now though....
