So, I still need to power it with AC adaptor? I did order it with the miniDSP that arrives Saturday. Do you leave it plugged in at all times? Does the automatic sub turn off still work?
Thanks!
Mine is powered all the time, and yes, my subs do turn off.

Jerry,
Could you have a look at post #3807 and see if I'm on the right track? Thanks again for all you help!

I just did the voltage gain test using a Fluke 114 True RMS voltmeter. I had audyssey enabled by mistake when doing measurements, does it really matter? With MV=0 (reference) SW trim was as follows:
-5.0 = .998V
-5.5 = .940V
-6.0 = .890V
So if I set trims for combined subs (75dB) at -6.0 I should be good?
Thanks!
Each sub gets .9v. You should be just fine.
