I recently wrote an email to the MiniDSP support and the response was confusing. I asked some questions about the DDRC-24m and they responded the following:
The DDRC-24 is a stereo Dirac Live (i.e. performing correction and time aligment on stereo units via Dirac Live.). I’m not sure of your application but it sounds like you’re trying to do a multisub setup?
If so, the MSO optimizer could be a better way to do it. It’s explained here on the DDRC-88A but the concept is the same for DDRC-24. https://www.minidsp.com/applications...-sub-optimizer
Bottom line, you need to first configure your unit first via REW + MSO software. THen you can run Dirac on top.
Then the confusion started for me as the DDRC-24 description said it have Bass Management support... something that the DDRC-88A does not have by default. This is the first contradiction on information received.
The second is that the Subwoofer integration with the DDRC-24 saids that "If you are using two subwoofers, you can connect the second to output 4." So, the DDRC-24 can manage or it cannot manage two subs?
If the DDRC-24 can manage two subs (as I suspect because have Bass Management and 2 outputs for that).... can it do it satisfying or taking into account what I asked?
1) Will the DDRC-24 provide a smoother room response of multiple subs (up to 2) while retaining time and phase coherency of both units at the Listening Position?
2) Will the DDRC-24 adjust the distance and polarity of the 2 subs individually then EQ's them as a whole?
3) If the Subs (up to 2) are placed on different locations, will the DDRC-24 EQ them considering levels, distances and other individual factors?
4) Will the DDRC-24 adjust each subs (up to 2) phase and polarity and provide a combined Sub output sound?
My current situation is that I have an AVR that has weak Bass Management. I plan to use the DDRC-24 to manage exclusively the bass. I currently only have 1 sub, but I plan to add 1 more (up to 2, no more) in about 1 yr. Can I use the DDRC-24 to manage (up to 2) subs into a single response and have no issue managing different levels, distances/delays, phases, spatial variation, etc...... or I really need the DDRC-88A and the REW and MSO stuff?
