I have just received an e-mail with information that it’s now possible to use EQ features while still taking advantage of the rendering capabilities of your MQA DAC.
But enabling EQ in DSP (all beside EQ is disabled in DSP) turns off MQA idicator in my Pro-ject PreBox ???
Um, the Pro-ject PreBox is a full Decoder and Renderer, no?
@Lonek When the first MQA decode occurs in Roon, the MQA Authentication takes place there too. If the light on the PreBox represents Authentication, then I would expect it to go out. Is there any other text on the PreBox? Elsewhere it has been posted that the PreBox shows “MQB” when receiving a decoded and renderable MQA stream. If so, then it’s rendering.
No no. If the device’s MQA Capabilities are set to “Decoder and Renderer”, Roon will do the “right thing”, including the MQA first decode (preserving the signalling information for rendering) if the user has chosen to apply DSP in Roon.
Martin, the MQA Capabilities setting is exactly that: it specifies the capabilities of the downstream MQA device (DAC or bridge); it doesn’t directly turn decode on or off.
With “Decoder and Renderer”:
When the user has configured DSP in Roon, Roon will authenticate and decode, and then pass a renderable signal to the downstream MQA device, which will (should) render it.
When the user has not configured DSP in Roon, Roon will pass the MQA stream bit-perfectly to the downstream MQA device, which will authenticate and decode.
The important thing to note is that the authentication cannot happen in the downstream MQA device if Roon has already performed the first MQA decode.
Make sure your device firmware is updated to the latest available version from Pro-Ject, I know they’ve fixed a few MQA related issues in the last update.
