DSP unit for three/four channels active speakers and Dirac Live

miniDSP has just published this application note about implementing a multichannel active system with Dirac Live:

Nice!  I have been looking for a solution I can recommend to friends that hear my 5.1 setup using three Xilica XD4080 processors (each is 4x8, so tri-amping 5 channels (FIR filters) plus time aligning 5 subs).  I know most want a car and not an audio system instead.

 

However, are the filters implemented after Dirac?  If not, my understanding is they will add phase shift and Dirac won't correct for this.

 

PS: any updates coming for the Windows Dirac Live software?  If so, I'm an electrical engineer and could be a great beta tester

@etc6849 in answer to your questions, crossover filters are indeed "POST" Dirac Live (i.e. will be measured and corrected during the processing of optimization). You can see the whole structure here: https://www.minidsp.com/products/dirac-series/ddrc-88bm

The user manual is a good start too... 85pages of explanations of how Dirac live works and how to control bass management + crossovers.  :-)
