Hello, I have recently bought a nanoavr HDA. Is there a way to upgrade it to DL Dirac version? Is it the same package available for HD models? Will the analog part work allthesame?
Thanks
Ludovico

Hi,

When we go to this page ( www.minidsp.com/products/ht-series/nanoavr-hd-to-dl-update ), it seems the firmware upgrade to Dirac Live is now possible for NanoAVR HDA !?

Does this mean the firmaware upgrade allow nanoAVR HDA to keep its functionalities (Bass-management, Analog conversion, etc.) and add Dirac Live support or it looses all its functionalities and become a nanoAVR DL ?

Thanks in advance,
Best Regards.

It's indeed correct that as of few months now, the nanoAVR HDA can indeed be upgrade with Dirac Live. Note that you'll loose all your BM settings though when you load DL. It will be like a nanoAVRDL.. IN the future, we can look into getting the BM into the DL but it's not possible for the time being.

Hi,

Thanks a lot for your answer. I'm using another external device to manage bass so it's not a problem for me.

But please could you confirm me analog output still working after nanoAVR HDA Dirac Live upgrade ?

Thanks in advance,

Yes, the analog outputs will indeed still work.. Else it would be quite limited upgrade.. :-)
The only limitation really is that currently we just don't have space in the DSP to add the BM section on top of Dirac. Hence that limitation explained above.

Are the above quotes more 'hopeful' than 'helpful'? While I appreciate the effort to expand the devices via software upgrades, and also to communicate openly about the 'possibility' of upgrades, it would be nice to have a bit more clarity.

The 1st post by DevTeam mentions "it's not possible for the time being" while the 2nd post adds that "currently we just don't have space in the DSP to add BM". Taken together, these posts reinforce the idea that BM will be added via software update enabled by some code optimization, etc. Is this correct? If so, any probability of this happening, and when?

I understood it more as:
The DSP processor does not have extra headroom to run the additional filters needed to implement the bass management. This would indicate that it will not be solved in software alone. I can only see this get done in the next hardware revision, if it has a faster DSP chip.

Your interpretation may very well be correct. However, the comments by miniDSP DevTeam could be taken as supporting the idea of software upgradeability of the existing nanoAVR HD. Hence, my request for clarity.

@DevTeam ... any chance of clarifying?

Unfortunately at this point of time, we don't have a path to solve this problem of combining BM and DL into one DSP resource. It's a resource limitation as mentioned by Erik.

Any comment on a new hardware version of this HDMI based NanoAVR? With so many sources outputting HDMI, it would be nice to eliminate expensive DA-AD-DA steps...

Unfortunately, we've got a policy of being very tight lip until we have something ready.. :-(
So unfortunately at this point of time, we don't have any update I'm afraid..

May I add my voice to strongly suggest an upgrade for those of us who bought NanAvr-DL and now knowing that it is not the top of the best implementation to get Bass management downstream instead of upstream. For us , the only solution is going separate (pre-amp_ 88-BMA - amp). I am sur that many of us can not afford it. The second solution (if I understood well my readings in others forums) is to get the best time aligment possible between the sub and the satellite first (with REW) to minimize the side effects of the path choosen for the signal. I saw also that Dirac had the same problem when implemented in AVR recently. I am surprise to see that Dirac did not specify clearly how to implement this beautifull software in the right order at the first place!

Hello,

Can I buy a Nanoavr HDA, upgrade to DL, and do this :
- HDMI input (LCPM 5.1 or stereo input)
- Use the 8 analog output
- Do FIR convolution for active filtering (cross over) and correction ?

That could solve all my needs !

Thank you !
