We are pleased to announce the release of dCS network firmware version 398 for all of our network streaming products. This version was released earlier this month for Vivaldi Upsampler and it is now available for Vivaldi One, Rossini, and Network Bridge. All of our streaming products will now be running on a common codebase.
This is primarily a maintenance release and includes a number of bugfixes and stability enhancements in all areas of the software. This release should significantly improve performance and stability when using Roon.
The release notes (linked below) contain details of the changes as well as preliminary documentation of new features. The update will be available at 9:00AM GMT on 29th October 2018.
There are no updates to any of the dCS apps associated with this release.
As with all of our network firmware releases the update can be initiated from within the dCS app:
Configuration > Information > Versions > Check for Updates
You can also update via the embedded web page by selecting the “Device Settings” tab and then clicking on “Check for Update” under the Internet update section.
Network Bridge owners will also receive a main board firmware update to 1.01 which is being released to address the issue of the front panel LED not flashing when the network firmware is updated. There are no other changes in Network Bridge 1.01.
Release notes for network firmware 398 can be downloaded from this link:
If you have any questions please don’t hesitate to ask them here.
It was clearly stated in the announcement and it was the same for the previous one. You can wait 3 days ? It is quite fair from dCS to announce it this way with a lot of information on the fixes, enhancement and still bugs to be fixed (missing the UPnP not gapless in the list).
After update Rossini Dac:
Playing a 24/96 MQA on Tidal.
Then switch to another album also 24/96 MQA
When I push the play button in Roon: a very loud klick.
Music is playing on the same volume.
Now no reaction when I turn the volume or push a button on the dac.
Also with the dCS app: no reaction.
Power off and on at the rear and everything works ok.
@roony, this sounds like the part of the FPGA that controls the front panel locked up. The network firmware has no ability to influence the device to that level. If this happens again please let us know.
Was this two redbook tracks going through a natural transition or did you skip to the next track? Were they both from the same disc? If you change the buffer setting on the DAC do you notice a difference?
What are your upsampling settings and filters in Roon?
How are the following settings configured on your Rossini:
Upsampling setting (DXD or DSD)
Typical volume control level
If there’s a Tidal album that exhibits the problem then please let me know what that is. I’ve been playing various redbook content through my Rossini all day using Roon’s DXD upsampling and it hasn’t made any noises at all.
Due to the way that Roon works I wouldn’t expect there to be any noise on transition. With or without upsampling the core sends a continuous stream as long as the sample rate / format don’t change. You could queue up 20 redbook albums and from the DAC’s perspective it would be just like playing a really long track.
I think “Decoder Only” is the answer. Rendering means selecting particular upsampling filters specified in the Decoded bitstream - which any rendering DAC should be able to pick up and render. The NB is NOT a renderer.
“Decoder Only” is the correct default state as there’s no way for the Bridge to know whether or not the connected DAC has a renderer. If an MQA-capable DAC is connected then the user can override the setting in Roon.
The difference between the two settings allows Roon to make decisions about how to handle the bitstream if it’s MQA.
With normal playback Roon sends the file to the Bridge and the Bridge does the MQA decode.
If Roon’s DSP is used then the behavior is different:
Decoder only: Roon does the MQA core decoding process, applies DSP, and sends that stream to the Bridge. That stream has no MQA signaling flags embedded so no further MQA processing can be done on it.
Decoder and Renderer: Roon does the MQA core decoding process, applies DSP, re-attaches the MQA signaling information, and sends that stream to the Bridge. This allows the downstream DAC to perform the MQA rendering stage.
In your case “Decoder Only” is the correct setting as the Debussy has no MQA functionality.
