yes it is an active sub.
i talked with audiopluss services and they said not to use the tape out because, as folks above have indicated, you can't control the volume. they said to take the top off the amp (after unplugging and letting it sit over night) and then see if there are loose connections. if the preouts still don't work, i'll send it in for warranty repair.
