I need a bit of help regarding the MQA.

I'm running Roon Tidal with a PC when playing MQA the 818.3 is displaying OFS and the frequency… my 7200SE are saying MHR.

Am I getting MQA if I go into Roon settings all set to pass through MQA?

Are your 7200SEs running the latest firmware?

I believe that the latest firmware for the 7200SE is 3.16. These are the release notes for the 3.16 8000SE firmware. 5200SE v3.16 are the same.

Code

<package version="1.0">
	<mfu name="N8kSE_3_16.mfq">Combine code for DSP8000SE</mfu>

        <h2>DSP8000SE Product Firmware Release 3.16 (2019-08-15)</h2>
        Combined controller and DSP code for DSP8000SE.
        <h3>New Features</h3>
        <ul>
            <li> Added displays and rendering for MQA Core material.</li>
        </ul>

        <h3>Software Fixes - Useful - May be useful to upgrade but not essential</h3>
        <ul>
            <li> None.</li>
        </ul>

</package>

Just been playing with Roon all working now looks like have to turn off bypass filters in DSP so MQA is working.
First time I've listened to MQA very nice glad I bought the 818.
Thanks All

You don't need to turn off the DSP in Roon. The OFs display on your 818v3 confirms that it's receiving a renderable MQB (unfolded) signal.

You need to update the firmware on your 7200s to get the correct displays.

Ok thanks for that. Do they have to be at a dealers to update them?

Only since I activated DSP headroom and volume leveling in Roon this weekend I get the “OF” display as well. Haven’t tried to turn all DSP off again. Roon is all latest fw.

I will check my Meridian fw again when back home next weekend but I think I have 3.16 installed. When was that issued, can’t be very recent I think?

Cheers!

Way back in 2019 ... from VK's post "DSP8000SE Product Firmware Release 3.16 (2019-08-15)".

No, but you do need a special cable to do it.

Can I ask what cable I need. Do you get the update from the Meridian website?

Hi Daz, Was this resolved already?

I was given this advice before:
Quote
Connect a serial ‘null modem’ cable from your PC, via a USB to Serial adaptor if necessary, to the green RS232 to SpeakerLink adaptor (you can get from your dealer or from the audio images shop), or you can also use an AC12.

Connect the Cat5 cable (or any other Cat5 or SpeakerLink cable) from this Green adaptor into the Input SpeakerLink socket.

The recommended USB to Serial adaptor is a Keyspan USA-19HS.
