Same calibration clipping problems. I used this instruction also. I can only calibrate at low volumes.
What version of dirac live are you using?Same calibration clipping problems. I used this instruction also. I can only calibrate at low volumes.
If the pipeline is working correctly, and if my db math is correct, here are some power figures for the M33, assuming 0db on the unit is max power:This amazes me also, but I don't spend much attention to that. Normal to a bit louder listening volume is around 76% which equals -26.5dB (no DIRAC, Tone controls, max volume is set to 0dB, 2.2. configuration) which equals to 66dB according to a dB app on my phone.
0 dB is loud enough, but not very loud. I am fine with that because of the neighbours in my building. But otherwise, it would have been a problem.
That could be the issue. Dirac Live website says to use version 3.4.4 with NAD. Anything newer can have problems. Dirac change log here: https://www.dirac.com/live/faq/helpdesk/software-changelog/Always the newest version. With a calibrated UMIK microphone AND with the NAD mic.
Glad to hear it was resolved for you. FWIW, when I did my Dirac measurements, I recall the system volume was something like -50db or -45db. Anything higher and the room modes would trigger the clipping warning. I have a room mode that adds 20db at 47Hz, so I can't blame Dirac for triggering a warning.Ok, I've done a new measurement with the DIRAC 3.4.4. version. Also I set my subwoofers at 50% volume instead of 40%. It was possible to make measurements at a slightly higher level than before (but by far not in between -12dB and -15dB as the manual states).
Now the NAD can play much louder than before. I do not even want to come close to the max.
Thank for the help, again. I hope this also helps the other poster.
I did receive the M33 back from the service. I can only conclude that it is working as designed. It is just not powerful enough when using Dirac in my setup, I don't like that I can max the volume (down to -10dB with dirac on) when I listen to some classical music like this one for example: https://tidal.com/browse/track/12720229Update: The support of NAD was responsive and we have spend quite some time and long phone calls to work on my issue. They could not reproduce the issue after extensive tests using my Dirac filters. Filter design seems not to be the problem here. I will be sending the unit to the nearest service center to check if there is a faulty component involved in the Dirac chain. To be continued...
These are my targets curves, crossover at 70Hz because of terrible bass response of the speaker in the right corner.What do your target curves currently look like under DL?
I'm not fully opening the curtains because I like the natural response of the main speakers better than with Dirac.You are giving away a lot of possible output power with these curves!
Why didn't you pull the curtain fully open?
Have you saved your target curves as files? Then you could simply restore the reserved headroom from DL.
3.4.4 as advised. Waiting for the latest version to be fully bug free...Which DL version are you using?
Thanks, I will try.+7dB, see also here as example: LINK
I've elevated the target curves by a conservative 6 dB to start with, this is what they look like.Thanks, I will try.
Your room curve should typically slope down in the higher frequencies. The curve you have now will sound too bright. If memory serves me right, I have around +6db in the low frequencies and then slope down about -1db per octave. You can find the ideal room frequency preference in Floyd Toole’s book.I've elevated the target curves by a conservative 6 dB to start with, this is what they look like.
It does indeed bring more volume, I have maxed out the volume to 0dB on the music provided in my previous post and I can clearly hear the volume difference when I switch between the 2 filters.
So this workaround works to restore some of the lost gain, Dirac and NAD should take note I think.
The filter did give the following REW response at the listening position when using the curtains, 1 measure only, and I'm quite happy with the the result, indeed for some people it could be too bright in the highs. My philosophy is more to not correct anything in the mids and high and to trust the engineer of the speaker, Cabasse in this case, I think that the Cabasse Murano Alto doesn't have a flat response in anechoic chamber like the older designs did, the result is totally non fatiguing and I can listen for hours.Your room curve should typically slope down in the higher frequencies.
