Problems with upgraded upsampler

Support

Okay, it should work properly with Audirvana. Yes, you can update from 2.00 to 2.10 on the DAC in one go, you don’t need to update to 2.02 first.

  • Make sure the volume control in the software is at maximum, 0dB. Anything else will make the update fail.
  • Make sure there is no upsampling turned on in the software.
  • Make sure fade in/out is turned off.
  • Are you connecting the Mac directly to the Vivaldi DAC or is it going into the Vivaldi Upsampler?

Your English is very good, MUCH better than my Italian :wink:

James,
I connected the mac via usb cable to the Dac. Correct?
With that unzipped file I can update from 2.00 to 2.10 or to the 2.11?
thks

James is that a typo? Should it be 2.11?

31

It was a typo yes, my mistake! It will update to 2.11 with that file.

32

Not able to make the update of the Dac from 2.00 to 2.11. Dac displays wrong disc. The Mac mini has to be connected to Dac or to the Upsampler? There is no clear instructions to do this upgrade in the net?
Thanks for reply.

Piero, easiest to just connect your Mac directly to the DAC USB port, and follow the instructions contained within the zip file your dCS dealer gave you (there’s should be a “SW Update note_VDC2_11.pdf” file that describes the upgrade procedure in detail).

Even without that pdf, the overall process is rather straight forward; put the DAC into “Update” mode, and playback the firmware upgrade WAV file bit-perfectly through the appropriately selected DAC input.

In the case of using your Mac mini over USB, be sure to select USB input on the DAC, and have an appropriate playback software (like Audirvana, with any upsampling disabled).

If that continues to fail for whatever reason, as an “old-world” alternatively, if you use a CD transport connected to one of the DAC’s S/PDIF or AES/EBU port (and properly clocked). Just burn the upgrade WAV file onto a blank CD as an Audio Disc with your Mac Mini, and then playback that CD via your CD transport while the DAC is in Update mode.

I hope my dealer can help me to make this upgrade.
In the meantime can you please let me know the correct connections from clock to dac and to upsampler?
Thank You

On the Vivaldi clock use the Freq 1 button to set the frequency to 44.1 and using Freq 2 button set the frequency to 48.

Using 75ohm BNC/BNC cables connect one of the group 1 BNC outputs from the clock to the group 1 BNC input on the DAC. Connect one of the group 2 BNC outputs to the group 2 input on the DAC. Using different group 1 and 2 clock outputs do the same to the upsampler’s group 1 and 2 inputs.

If you look at page 9 in the clock user manual you will see a 4 box Vivaldi set up connections illustrated. Just ignore the BNC clock connection to the transport.

Thanks Pete. Following scheme pag. 8 of clock manual, connections ( 75 ohm cables and 110 ohm 1+2 from upsampler to 3+4 to the dac) are correct. More difficutlies to connect properly all samples rate and MQA files from Tidal. While 16/44 files are displayed correct on the upsampler ( W1 ) and on dac you see W1 too with no red error, why in the mqa files reproduction I see a red error on Dac?

39

The story so far as I understand it is that you have been unable to load updates and still have v.2.00.

The MQA facility needs at least v. 2.10 so that is probably the explanation.

Ok Pete. Now I understand all my problems…Tomorrow I will contact the dealer to make the Dac upgrade.
Thanks so much

Hi all.
As my local Dcs dealer has installed the new board on my upsampler without first installing the new software upgrade on Dac ( from 2.0 to 2.11 ) and not following these instructions Release Notes: Vivaldi DAC 2.11 / Vivaldi Upsampler 2.10 [MQA Release] ,
I am wondering if now I can make the software upgrade on Dac or not… He does not know…
Thank You
Piero

42

You will be able to update the DAC from 2.0 to 2.11, yes. The note in the release notes that the DAC and Upsampler must be updated at the same time is for a separate issue; nothing is broken, but once the DAC is updated to 2.11 all compatibility and functionality will be restored. You should not see any issues in performing the update on the DAC because of the Upsampler being on 2.10.

Was your dealer able to offer any direct assistance with performing the DAC update?

43

Poor Piero has been struggling with this since May! I have to say that his new posting regarding his dealer’s knowledge does suggest that some additional training is required. I would be scandalised if I got the level of dealer support that he seems to have suffered.

Thanks James and Pete. Local dealer assistance is zero. I did know it before asking to Uk Dcs to make the upsampler upgrade in Uk…Local dealer told me the upsampler is perfect ( forgetting that he had to upgrade the dac at the same time of upsampler). In addition he told me do not disturb anymore. What the dealer is for?? Problem is still here…
sorry for the outburst

46

Perfectly understood. I hope that this thread is brought to Rav’s attention ( James?).

@cuprone I will send you a private message to get some more details about your unit so we can get this resolved as soon as possible.

It has been, yes.
