For stereo input, just use two Dirac channels and route to the output channels in the Mixer tab (not the Routing tab), like this:

That is assuming you have "left and right subs". If you are mixing the subs to mono then:

If you really want to do the thing the HT people insist on and do the sub crossover before Dirac, that's a different arrangement, but I would suggest getting it working this way first.

Of course I will setup the crossovers after I get my brain working on routing. Again thank you very much. Vince Attachments: 88A-2.xml (78KB)

john.reekie Offline Platinum Boarder Posts: 3405 Thank you received: 1448 Karma: 134	Right. FYI you are not using the output from the LFE Mgt tab, so you don't need the inputs to the LFE mixer turned on. (Not that it matters, just in case it may cause confusion)

The issue is that you would be basing the crossover on a measurement of the wrong thing. The individual drivers should be measured, corrected, and crossed over without influence from the room. Then you correct the whole thing and the room with Dirac Live. So what you were thinking may "work" but may also produce some strange results.

compaddict Offline Junior Boarder Posts: 34 Karma: 0	Just got everything setup today and all is well! I had an error in my sub crossover that threw us off a bit.. But after that it all worked well. I need to redo my driver levels and do some EQ work but I ran Dirac Live just to see what it would do. Very impressed. Powerful stuff indeed. Thanks for all the help! Vince
