Why can’t I turn off power switch.

There is no power switch. We just turn off all the amps first, then power to the whole amp rack. Reverse order when powering up.

How good is this product?

Yes. I think this is a good product. I have it in a rack for my Karaoke and DJ shows. I have not had any issues with it.

Using the unit in 3 way stereo, does it still provide subwoofer output?

Yes, you set the crossover points between low and mids, as well as between mids & highs. You then have a left and right output each for subs, mids & tweeters. We're using it exactly this way with our stereo 3-way mains and very helpful for setting overall system frequency response before optimizing with a stereo 31-band eq.
