TOPIC: DDRC-24 + Dirac 2 for Sub Only Application?

I have been successfully using a DDRC-24 + Dirac 1 for a Sub only application (Denon sub out => DDRC-24 => Sub). I recently updated the DDRC-24 to use Dirac 2 but I cannot seem to figure out how to get it to work for my sub only application. I just updated to the latest versions of Minidsp and Dirac2 again today (11/27/2019) and tried again. I have attached the errors that I receive during the attempt to make the first Dirac 2 measurement (get one error or the other each attempt). The freq sweep sounds fine out of the sub. I believe the problem is that the Dirac 2 software expects to see a response over the entire freq range and not just the lower freq range covered by the sub.

Is there any way to limit the desired freq range for Dirac 2? Any other suggestions?

Dirac 2.0 indeed expects full range when doing a sweep. That's why you're getting that error for the new algorithm.
As a workaround, maybe see if you could connect one main speaker (e.g. Left speaker) just for the purpose of having a full range signal during the sweep. i.e. IN1/OUT1 = Left, IN2/OUT2=Sub. Once the measurement done, you can disconnect the left speaker.
