Since you guys in this thread have the most real world experience with Dirac, I thought I would ask here. Emotiva is about to enable Dirac on the XMC-1. The XMC has two independent sub outputs, and I have 4 subs. I can set this up one of two ways..
1) Use my current setup where I have time aligned the 4 subs with an outboard Xilica processor and the help of some fine folk at the Home Theater Shack and REW. I would connect the 4 subs to just one output of the XMC as I have now and let Dirac do its thing while "hearing" the combined response of all 4 subs on that one output.
2) Connect the front and rear subs to one output and left and right subs to the second output, turning off all attempts to time align the subs in the Xilica. The front and rear are pretty close to the same distance from the MLP (maybe a foot difference at most I think) and the left and right are also similar. Then just let the XMC Dirac setup hear each set of subs separately and do its calculations.
I realize the XMC's iteration of Dirac may differ a bit from the Datasat, but if you assumed that the Datasat had only two sub outputs, which of the above methods would you use?
... I also suppose that if it mattered I could attempt to make the time alignment of the front/rear and left/right even closer by still using the delays of the Xilica even if I chose option #2
above instead of just letting them pass the signals through.
Thanks for any help and I don't want to hijack a Datasat thread, but there will be limited users of the XMC with 4 subs and an outboard EQ at their disposal and you guys have great experience with this.
