The song needs remastering process at lower volume.
It is clipping constantly at plus 0.7 dB true peak, measured with Youlean Loudness meter.
you can lower the gain of your play software ?

yes, in fact just applying replaygain is an effective fix.

This what's left when the track is steeply lowpass-filtered at 1Hz! (8th order)

No wonder it triggers the protection as the DC-levels are significant (-27dBFS == 4% of FullScale) plus useless infrasonic content.

Extemely bad recording and mastering at work.

Thanks for the analysis.
Let me state explicitly: I'm not saying that this song is a "false positive" of some sort.
My concern is a bit different: after installing the firmware update, it took less than 24 hours to trigger the DC protection warning.
I admit I didn't compute the probability, but from these numbers the issue doesn't seem "uncommon" and -if this is true- I strongly feel that a more "forgiving" workaround is required.
Otherwise users will perceive the "protection" as an annoyance, and just turn it off (which is bad).

Usually I don’t like speculations but this time I can’t hesitate to give a bet:

As the new DC protection measures the DC content of the audio signal it might be a DC-servo function that nulls DC output.

Good Morning from Hongkong.

Could be I am the first one encountered the Digital DC protection during the pre-test session, within 30-40 minutes of internet radio.

We do not know the recording is bad before, and play it loud, possibly damaged something and never know the cause and live with it, now this new function let us know and can protect downstream equipment, not bad at all. I think that is a good feature, though a bit trouble for some applications.

If let it off, the warning screen still shows, audio goes on, feel even worse after saw the warning screen, who can live with knowing something bad happens and let it stay and keep on listening?

A more forgiving protection or turning it off, it reminds me the name of a tennis star, or put a copper bar instead of a fuse.

Let's wait for the next firmware, I am confident MC and the RME team will find the best way to make it works in a better way.

Use the first aid MC recommended and kindly be patient for the next update.

I also came across a song with the same problem. If you have it downloaded locally, you can use Effect>Normalise in Audacity. First apply the DC offset. If the song keeps triggering the DC warning, keep lowering the gain until the warning disappears. Export the new file and good job, you are better at mastering than the sound engineers themselves.
