D2 MQA settings

@Cedric_TOQUE

the Lumin D2 as decoder and renderer is equivalent to the renderer only when the MQA Roon Core decoder is enable?

In the absence of Roon DSP, yes.

@Cedric_TOQUE

When the Roon Core decoder is turned off and the Lumin D2 as renderer only is equivalent to the Lumin as decoder and renderer?

No. Without MQA Core decoding in either Roon Core and Lumin, MQA is not processed.

Ok, but when my Lumin is on renderer only and I turn off the roon core decoder, the screen of my Lumin indicates MQA and the signal path in roon too.

By incorrectly turning off the MQA Core decoder, you prevented the Renderer-only configuration from working. This forces the endpoint to do the full processing when it is not necessary.

This is not a practical difference between MQA display and OFS display. The former includes authentication, while in the latter case it is already authenticated in Roon Core as shown in the signal path.
