Meridian upgrades speaker firmware for MQA

Version 3.16 implements MQA rendering for DSP8000.2, DSP7200.2 and DSP5200.2 from a MHR (Meridian) source, as well as for all Special Edition speakers from any MQA decoder. As a result, I can do the first unfold in Roon, use DSP processing (room correction in my case), and then forward the MQA signaling information from my Allo endpoint to the speakers for final unfold.

I just had 3.16 installed, in an all-Meridian system (218 + DSP7200SE), but in my case it doesn’t work that way. The idea was also to use DSP processing (Acourate room correction), and then forward the MQA signaling information from my 218 endpoint to the speakers for final unfold. The new 3.16 firmware won’t allow that. Bummer.

@Peter_Overbosch I suspect that we need to wait for updated Meridian controller updates… I’m in the same boat with my 818…

To be clear:
Meridian has announced that they will issue firmware updates for 808, 818, 218 and 251 in the future which will allow for DSP between the first unfold in Roon and the final rendering in your 3.16 upgraded speakers.

Someday. Not yet.

Took delivery of my 818v3 last week, with the new 4.14 firmware, playing to 7200SE speakers with 3.16 firmware. No DSP between the first unfold in Roon and the final rendering in the 3.16 upgraded speakers. Unfortunately. Someday perhaps. Not yet.

I don’t know what you mean by this.

I am currently running first unfold in Roon + DSP in Roon, into my 818v3’s ID41, then into my 8kSEs. 8kSEs display “OFs”, showing that they are indeed rendering. 818v3 also shows “OFs”.

That is precisely what I would want, but it doesn’t seem work that way in my setup. Things are very similar: running first unfold in Roon + DSP in Roon, into my 818v3’s ID41 (firmware 4.14), then into my 7200SEs (firmware 3.16). Tried MQA 96 and MQA 192, but in all cases what I see is MHR 96 - MQA or non-MQA. There is no mention of “OFs”. I am very happy to learn that it can work, just need to figure out how in my situation.

If you get your MQA files through Tidal, note that Tidal has said “Loudness normalization” (in their streaming settings) should be turned OFF for MQA listeners following a recent update by the service.

Tried that (thanks for the suggestion) but it doesn’t make any difference. I have tried a number of settings now, switching off everything not absolutely needed and experimenting with various settings under “DSP” in Roon, but there is no way I can get to an “OFs” situation. Without DSP the MQA process seems to run just fine - and is indicated as such on my 7200SEs - but with DSP in the loop things just revert to MHR. Maybe Meridian support has a suggestion, I will try that now.

One final thing. Is your 818v3 set up correctly for DSP speakers? You need the following settings:

  • Fixed volume.
  • MHR = Yes.
  • Speakerlink support = Yes.

Thanks for the suggestions. I set fixed volume in Roon (that is new for me) and I looked for MHR and Speakerlink support in MConfig - did not find a direct reference there, but my speakers are connected through speakerlink and MConfig clearly reflects that. MHR is also clearly supported.
As mentioned, the fixed volume (in Roon) was a new setting to me, but it still does not give me OFs.
In the meantime I have also reached out to Meridian support.
Thanks again, Peter

In the meantime I have found these settings in the 818 setup menu:

  • Fixed volume.
  • MHR = Yes.
  • Speakerlink support = Yes.
    So thanks again - but still no OFs. Waiting for Meridian support.
