Ok, i hooked up the sub on the second coax output > DAC > sub


but when i start dirac live there are only left/right chanel and nothing comes out from the sub.
How to integrate the sub in the measurements ?
I want that dirac makes the time and phase alignment ...
Or do i have to measure separately, but then how works the integration ?

I'm afraid the 2 channel version of Dirac on the SHD can't do this. You need to make your own measurements to determine this, set the time delays needed on the main speakers (assuming they're closer than the sub), and then run Dirac.

Hi rusev,

There seems to be a Problem with the digital Outputs. Try the other one or use analog output 3. I have two subs connected to analog 3 and 4 and it works fine. Remember to have the configuration with sub active when starting dirac.

Good advice. That's probably the most likely reason the OP didn't get sound from the sub when they tried I'd say.

(Going by the OP's signature I think they have an SHD Studio and so analogue outputs aren't an option.)

PS: You should use the upper coax rca since this one delivers channel 3 and 4 as it says on the back :-)

PPS: I wouldn't let the main speaker run the whole spektrum. I use a highpass for the main speakers which results in a much cleaner bass. I tried both and decided to use it this way.
