Meridian Explorer 2 MQA renderer only?

I thought I’d try letting Roon do the first unfold and a Meridian Explorer 2 do the final rendering as opposed to the Meridian doing both.
However, I can’t seem to achieve this, is there something I’m missing here?
The DAC’s attached to a Pi running Ropieee, but the same behavior goes when I connect it straight to a computer running Roon remote.

Hi @sohe68,

You’ll want to right click the Explorer2 zone next to the Volume Controls (bottom right) -> Device Setup -> MQA Capabilities -> Render Only.


Thanks, yes did this already. Changed from “Decoder and renderer” to “Renderer only”.

Hello @sohe68,

Due to a firmware limitation in the Meridian Explorer 2, the DAC only supports MQA unfolding when sent a bit-perfect un-decoded MQA stream. If the audio is put through the MQA Core Decoder before being sent to the device, the Explorer 2 will not complete the MQA Rendering process.


I’m seeing the following Signal Path (RPi 3B+ powered by RoPieee):

There is an additional step: Preserving MQA Signaling.
Device Settings = Decoder & Renderer.

OK, that explains it then. I seem to recall that rendering works in combination with the Tidal desktop app doing the first unfold, but I might be mistaken. If so, is this a limitation with Roon?

I think this is because you have DSP engaged with a Crossfeed filter.

Now with Device Settings = Render only.

and with DSP disabled and Decoder & Renderer which will display the blue led.
