My fronts are full range, going down to 24Hz (-3dB) and when playing 2-ch music, I do not like to use the sub. Previously, I had the Bass Management menu Adv Setting = Off, but the ARC changed it to 'On' and set xover points for all the speakers. From what I observe, the change seem to be permanent, whether EQ is off or on.
When you set Room EQ = Off for any given source, the ARC filters are disabled for that source, however the speaker levels and crossovers that ARC calculated are maintained. I.e., the settings you now see in Setup / Level Calibration and in Setup / Speaker Configuration (for the cross overs) -- the settings ARC altered as part of its Upload -- are used whether or not Room EQ = ON is set.
The first thing to try is to run ARC in "Advanced" mode, and tell ARC that you want a separate Movie and Music configuration, and that you *DON'T* want the subwoofer included in the Music configuration.
ARC will measure at each location for your Movie setup and then start over and measure again at each location (which might, I suppose, be different) for your Music configuration. It will then calculate levels (common to both) and cross overs (different for Movie and Music) and present those cross overs to use as it's "targets" -- viewable in the Target window with separate results for Movie cross overs and Music cross overs.
So do the measurement that way and then see what ARC has come up with for Music cross overs. Since you have excluded the sub from the Music configuration, the Music configuration crossovers for your main speakers should now be set quite low or perhaps even disabled.
Now you can have ARC do its calculation based on that set of measurements and targets, or, if you prefer, you can alter the target crossovers shown in the targets window for the Music configuration and have ARC run its calculation based on those manual cross over settings.
Either way, now Upload the results to the D2.
Your Movie setup will be as before, and your Music setup will now show that the sub is not included in the configuration and the cross overs for the mains are as you had them in the ARC "targets" window prior to it doing its calculations.
NOW when you switch between Room EQ = ON/OFF for your Music sources all you are doing is taking the ARC filters out of the equation. The cross overs in the Music configuration will be as you set them in the ARC "targets" window for Music either way.
Beware however that if you CHANGE the levels or cross over settings in the Setup menu *AFTER* Uploading ARC results, that such changes will effect ARC audio as well -- meaning the ARC calculations will no longer be valid. The correct way to alter the crossovers is to do it in the ARC "targets". Then re-calculate based on your prior measurements and these new targets and upload the results. You don't have to re-measure. Just change the targets, re-calculate, and Upload the new results.
[EXCEPTION: For technical reasons that I confess I do not understand, the above warning is NOT true for the subwoofer cross overs. If you change those in Setup / Speaker Configuration after Uploading ARC results, such changes will *NOT* alter ARC's audio. It will only alter audio when you select Room EQ = OFF for some source.]
In particular, this means you need to Save User Settings and/or Installer Settings after Uploading ARC results to make sure the current levels and crossovers used by ARC in its calculations are saved in those memories. Otherwise, if you Reload User or Installer Settings any differences in the old, saved, cross over or speaker level values will screw up ARC audio.
