Help with Dirac live and NAD C3050 needed :)

[Stulle]

Hey first post and english is not my first language. so i hope i dont make to many mistakes here =)

Okay lets start with my question(s):
My dad has bougth a NAD C 3050 with the MDC2 module. now i have installed everything in my room and connected my floorspeakers (Elac FS 287/Solano) and a subwoofer (B and W asw610xp).
The Subwoofer is connected via the line in port/Low Pass Filter is disabled and the low pass freq shouldnt matter because the line in port is used (if i understand the manual correctly). One of the reasons why it was bought was an hopefully easy sub implementation and as a replacement for an old marantz amp.

So i tried to implement dirac today. At the point where i apply the dirac live correction the subwoofer stays silent. when i run the mesurement everything was fine..

just for testing purposes i tried another measurement, here some pics from the dirac program:

in this pic i dont understand why there is a warning sign at the measurement position- the program said the measurement was succesful (i know that only one position was covered)

here i have many questions... i set a target curve as nad recommended (its a target curve by nad that i have found here: https://nad.de/dirac-live/) now i cant set a crossover frequency from speaker to subwoofer.
1.is the functionality limited because i dont have the full dirac license? i know that the freqency band is limited but no crossovers (?)
2can i set a crossover if i buy dirac upgrade for the mcd2 module?
3. there are those blue buttons on the upper righthand corner but i cant see an explanation. nowhere.... in some vids on youtube they dont appear.

Would love to get some help =D maybe i should have bougth a minidsp instead ...

little pic of the current setup maybe the placement could be much better but at first everthing should just work....

greets from berlin

additional information, the crossover frequency is also adjustable in the menu from the amp... but nothing changes, the subwoofer stays silent when i apply a dirac correction curve. without dirac evertyhing is fine (but no dsp.... )


edit:
evening now and tested some more stuff. sub is now disconnected and i have run another dirac mesurement, with the dirac mesurement applied the bass seems to disappear in the listening position (???) everywhere else in the room you can here the bassline ;D source was now a cdplayer. i really dont know what i do wrong or is the positioning of my speakers so bad in this case?

 

[Stulle]

seems like i create my own thread searched somemore and found now this thread with the same problems?
https://www.audiosciencereview.com/...ubwoofer-output-nad-m33-and-dirac-live.49837/
next problem, i cant find a download soure for version 3.4.4 of dirac live. :/ confluence . dirac . services seems to be down


edit: in the other thread linked above someone posted a working download link. I will test it tomorrow

Dann machen wir morgen hier weiter

Dirac Change Log

Roll back the software to 3.4.4 and try again.

• "on some NAD devices the subwoofer outputs don’t get sound with Dirac On on some NAD devices
• We therefore recommend NAD users to stay with Dirac Live 3.4.4 until we have fixed that problem."

 

[RickyC34]

Once rolled back, make sure to apply the target curve to both the mains and subs. Once uploaded click the blue + on both the subs and mains. I don't have any experience with the NAD or Dirac on any AVR but setting the crossover should not be limited by which version of Dirac you have. Currently, you do not have the NAD curve applied to the mains. Clicking the + will apply your loaded target curve.

a huge thank you to all of you. it seems to work now, and there is also a hearable diffrence with/without dirac (in a positiv manner)
Nad actually seems recommend to don't use the target curve with the sub but i tried it an works well
i just dont understand clearly what you mean by pressing the + or do just just talk about this --->

aaaand i still havent found the option for the crossover (?) but i can set a crossover in the settings of the amp so it should be fine. maybe i can try to make some mesurments with rew if i can figure out how to use the nad mic with my pc or maybe i should by a umik when i have some time )

all in all i was yesterday a bit frustrated because the nad website doesnt mention those problems and they try to sell it like a complete-build-in-soulution/you dont have to think about it.

thank you @pogo and @RickyC34 !!!

No problem, but you have to load the NAD mic correction data into REW additionally.

As I said I don't have experience with NAD or AVRs with Dirac but loading the target curve to just the Mains is something I've never heard of. Do you have a source?

Yes, that's what I meant by the +

aaaand i still havent found the option for the crossover (?) but i can set a crossover in the settings of the amp

Maybe I was wrong and with an AVR this is the only place to adjust the xover with DIRAC via integrated or AVR.

I have the C3050LE and a full range DIRAC licence. Filters were made on DIRAC 3.4.4, the last version up until 3.9.7 that was "NAD bug free". No problems.
However, I just updated the NAD/BLUOS to yesterday's release of 4.4.10. Oh, now the volume with DIRAC on is much louder than before, and much louder than off.

Somehow, the bug that apparently existed between DIRAC 3.4.4 and 3.9.7 (hence don't use them), is back! Neither DIRAC 3.4.4 or 3.9.7 is supposed to have this problem.

I updated DIRAC to 3.9.7 and re-calculated all my filters from my existing projects, but I'm still having the volume issue. I've lodged a ticket with BLUOS.

I guess I can rollback DIRAC and BLUOS (manually), but the DIRAC project files have probably been updated in some way and I may have to redo the measurements. Not sure I really want to do that. Two different sets of stereo speakers, a SS and a valve amp to correct for!

I wouldn't change anything and wait for the answer from support.

You can't easily roll back BLUOS anyway . I received a response from BLUOS already and they have replicated the bug. They expect the tech team to work on it and release a new update at some point. Which is as good as one can hope for with these things I guess.

 

[pogo]

I've been running the fix for hours
Just run an update.

Oh, I see they just released one, will try!!!

Hi,
I also run the NAD C3050, plus Bluos and Paradigm founder speakers, sounds great, but I wanted to add a sub as well to cover the low frequencies....
However I don't get output from the sub out on the amp, it gives a big "plop" when I disconnect de plug, so there is a signal, but no sound.

I use a Paradigm 12"driver with a Hypex 4.0 plateamp, it has a low input, line input and the normal high input through speaker wires that does work, but I prefer to use the sub-out ofcourse.

Questions:
- Should I remove the jumpers from main to line out at the back of the amp when I use the sub out?
- When I run Dirac the speakers calibration makes the white noise, the sub though a loud "woop-woop"sound, that doesn't seem right at all?
- I put sub on the Bluos app and tried to run without Dirac with no effect...

Can someone help me figuring this out?
