dCS is pleased to announce updated firmware for the Vivaldi DAC and Upsampler. This release brings to a close our ongoing project to include MQA support in all of our current products. Properly implementing MQA in the Vivaldi separates was an extremely complex undertaking and presented a number of challenges. Although this release is delayed from our original announcement, we feel that the end result is well worth the wait.
dCS Distributors received the Vivaldi DAC update today (16th October) and will be working with their dealers to provide the software to customers. The Vivaldi Upsampler update will be posted to the server on Thursday, October 18 at 8:00AM GMT.
Update notes (IMPORTANT!!)
This update changes the way in which the dCS Vivaldi DAC communicates status information back to the Upsampler. This change will greatly improve the behavior of the system when the DAC and Upsampler are coordinating activities. As the new communication mechanism is incompatible with the prior mechanism the coordination process will fail if the Upsampler and DAC are not updated together. This will result in unstable behavior during sample rate changes, improper function of the volume control in the dCS app and Roon, as well as apparent failure of DAC settings changes made in the dCS app.
It is critical that you WAIT to update the Vivaldi Upsampler until you are able to update the Vivaldi DAC at the same time.
Please contact your dCS dealer or distributor to get a copy of the Vivaldi DAC update before you update the Vivaldi Upsampler over the internet.
We have issued release notes pertaining to this update in two separate documents. Please read these documents before starting the update process as they both contain useful information.
