Help! Anthem STR preamp ARC sounds bad now compared to off


Last time I used ARC, it made an appreciable positive difference.  Smooth, clean, and bass was deep.

I redid it yesterday, using 10 positions, and two subs, and it sounds much better, not louder, better with it off.  ARC is cancelling out all my bass.  It inverted the subs polarity, when i switch it to normal, bass comes back and is powerful.

I wonder if using 10 positions did something strange. 

Note, I also used the phase testing portion of ARC too to ensure speakers and subs are in phase. 

Did I do something wrong? How could it mess up this bad when it seems to have done so good on my first try a few weeks ago?

Anyone wrestled around with best practices here?

Anyone know how to copy settings from Profile 1 to the others?  I can't figure it out and am probably missing something obvious.
I can't believe the phasing is only applied to profile 1, that's crazy.

I agree, and I consider it a bug. I was hoping that Anthem had fixed it by now.

My subs have their own phase controls, which I adjusted by another method; the result is that the STR doesn't move the phase adjustment from zero. That's neither better nor worse than letting the STR do it, but it does keep me from knowing whether Anthem has fixed that yet.
Thanks for the advice.. I might can try again tomorrow.  I can't believe the phasing is only applied to profile 1, that's crazy.
@dtximages - Yes, the phase adjustment is applied only to Profile 1. That is documented exactly nowhere, but I discovered it when I noticed Profiles 2-4 were deficient in bass. (I've reported it to Anthem as a bug.) As I mentioned, you can use the preamp's menu system to check the phase settings of Profile 1, then copy those to Profiles 2 through 4.
You might want to try measuring again, but I suggest you do move the mic around. To get best sound for a single listener, or if you are using a directional speaker, it may be best to move it less than Anthem suggests, but do move it a little. It's the spatial averaging that prevents effects that are strongly position-dependent from being "corrected".
yes i am young in my audio journey

arc means Audio Research Company to me... but i am a noob

don’t know much about anthem, i will admit that, stopped paying attention when sonic frontiers folded and chris j started partconnection

Wait what?  It only applies to Profile 1?  Well that changes things.

I actually think 10 locations might have been the problem too.  The first time I ran ARC, I used 5 locations, but never moved the mic from the first position. 
Hard to say, but if you post your PDF file, I’ll take a look. I have an STR preamp, also.

Are you aware, the phase adjustment
  1. should be made with the mic at the main listening position,
  2. should be made AFTER you have uploaded the corrections,
  3. and AFTER you have set speaker distances, and
  4. will be programmed ONLY into Profile 1 of the preamp?
You will need to copy the phase settings from Profile 1 to the other profiles, if you use them.

I have never used more than 7 positions for measuring, so if there is a bug with 10, I wouldn’t have experienced it.

Hope that helps.
