Hi all,

After a long rebuild of my home theater I planned to rerun DIRAC on my setup:
  • Marantz AV8805 - 15.2 speaker / sub lay-out for Atmos, DTS:X & AURO 3D
  • Dual DDRC-88A
  • 14 Channel power amps

I used to route the LFE from the Marantz through unit 1 (ear heights) to unit 2 (ceiling speakers) including output to dual subs which were PEQ'ed with MSO. And now my issue; since I updated to DIRAC 3 I have issues with this routing. When I ran DIRAC on unit 2 everything is perfect and subs are corrected by DIRAC. And than ran it on unit 1, result.... Double DSP on the LFE channel. I assume it doesn't matter when I run unit 1 first because I will still have DIRAC correcting both subs on both units while calibrating. Am I missing something? Is there a way I missed to route the LFE (pass)through unit 1 to unit 2 and still benefit of BM in both units with only correction on the LFE in unit 2? Can this be done using rev 3 or do I need to downgrade to previous firmware?

Hoping for some help and advice :)

When you run Dirac on Unit #2, don't include the subs. Just the 4 ceiling speakers. When you do Dirac on unit #1 DO include the subwoofer channel
