Dirac ART on Marantz AV10

[smile nya]

Can someone post a screenshot of their av10 setup screen for Dirac? Does it say art? No matter how many times I export the filter, the av10 never recognises it as ART even if Dirac live does. Not sure if a visual bug in the setup or a problem in my device

This is a problem that many people have been experiencing since Art's release. There are just too many bugs.

I do not have an AV10 but, in general, "ART" is in the calibration process. The files that it outputs are the same filter types as all other Dirac files and there's no way for the target device to detect how they were made. You might consider naming the calibrations as "ART" if you want to see them as such.

Sure there is a way and the target device should and can detect it (and display it). For example it changes bass management engine based on that info.

You should see a difference. I use web interface for most things so first is screenshot with Bass control (formerly DLBC), second with ART

This is correct, here's another from MacBook...

Is there a tutorial video to watch before I start?

 

[Ockingshay]

trying this for the first time with latest software and ART…

Is it normal to have the mic gain set to +30 and master output to -16 in order to get a sensible level being picked up by the umik-1?

This microphone seems to be incredibly insensitive. I had run an old version of Dirac live to fix this issue last time.

 

[Oddball]

It is recommended to set the mic to the middle. If you set it lower or higher it would not be a problem if within the limits, but than Dirac will set appropriate negative or positive trims.

 

[Ockingshay]

That’s my problem though, I can’t. Any lower and the levels don’t get picked up. Is it a dud microphone?

FWIW, I barely need to move my UMIK-1 gain up from the default.

Ok, so def something wrong with this mic. Such a pain as they are a nightmare to get hold of in UK.

Is it worth upgrading to umik-2?

UMIK-2 supports 192 kHz sampling, but I don't think Dirac can take advantage of it (limited to 48 kHz on most hardware). So it's up to you. It's not unheard of to have a dud UMIK-1.

Thanks for your help, New mic ordered, never straight forward with me

Have you tried a different USB cable yet, use one not longer than 3 meters, just to prove if the cable might be defective.
For the purpose, I see no reason to pay so much more for the Umik-2, none whatsoever.

I thought UMIK-2 might help avoid measurement failures, but it didn’t. As others have mentioned, the USB cable quality actually matters. If the issue is due to insufficient USB power, a self-powered hub might fix it.

Pretty sure it's locked out. This is Audy only feature and only for speakers designated as large.

In theory, if you assign your low end capable bed channel speakers to support the subs, you would get ART version of the LFE distribution, which is obviously different - and all say better.

How do you know this is an Audyssey feature as opposed to a Denon feature. I have a 4800 with this feature.

 

[davidc]

ART is just playing cancellation waves to reduce decay below 150 Hz through destructive interference. ART is not content. LFE is low-frequency content specifically mixed into a dedicated channel by the sound mixer (either during production in case of a DD track on a Blu-Ray or in real-time in the case of a game on a console). LFE Distribution takes that content destined for the ".1" channel and feeds it back into the other channels you specify (after being attenuated by a specified value). It has nothing to do with room correction beyond the fact that it's tied to Audyssey as an implementation detail. As I understand it, StormAudio has a similar capability (as described by Gene at Audioholics) that can run alongside Dirac.

So, the LFE distribution is not used when using any Dirac product, is that correct? Live, BC and ART?

This is D&M firmware feature. Will work without any EQ on top of it.

But you would not want to use it without any room EQ way so my reference was to Audy as the only EQ system that supports this feature.

With that, not sure why interested in LFE distribution when we have ART that offers so much more? LFE distribution was interesting when was released as it was something similar to what much more expensive gear like Storm and Trinnov were offering at much lower price point. I would not not want to go back to the LFE distribution even again.

Well, LFE distribution (as well as Audyssey) is good for me as I'm running a 5.0 system (I do not have any subs). My main L/R speakers are VMPS Supertower III's, which are very capable of bass as good as any sub. Because of this, it's important that the LFE channel gets distributed to the L/R speakers.

So, now I have a choice to make...I can keep the same speaker setup, and run Dirac Live and Dirac ART (I am not forced to use Dirac BC). Dirac ART is confirmed to work without subs. But, I do know that with ART, the more the better, so I'm considering using the two passive subs I have in the garage (I would use seperate power amps that I have). But, I want to confirm that I will still get bass (and LFE) distributed to my main L/R speaker. I would also use Dirac BC in this case of course. I have heard conflicting info as to whether Dirac Live and BC will continue to send bass signals to my main L/R speakers.
