On the DAC (not Pro), latest firmaware, for the Line Out: no OVR is displayed on the post-FX meter if I set the Volume above 0 e.g. at +1. OVR shows up when I put the volume at +2.5
I guess this is a discrepancy between the DAC and the Pro. Why? I don't know

But the headroom for the Phone Out is actually +1dBFS.
Line Out and IEM (DAC) have indeed a +2.5dBFS headroom.

As stated, I have the ADI-Pro 1st edition.
It’s with the AK4490 DAC chips that doesn’t have the headroom like the “FS”- models.

In Firefox you need sometimes to load the graphic 2 times until you get a pulldown menue to open it in Windows Foto Display, there you get is then in better quality (compared to the rendering of Firefox). Don't know how this is with other OS/Browsers.

This headroom is there to handle InterSamplePeaks, but can be used to cleanly reproduce “normal” mixes at a Volume setting of +1 dB.

If you do so, of course the output is 1 dB louder than the original.
If the Over display is disturbing you, just go back to a Volume of 0 dB.
This doesn’t change anything on the sound.

Ar .... he set the output 1dB higher than the source .... thought he is set at 7+1 = 8dBu ....

I am. +7dBu and +1dB vol. With +7dBu and 0dB vol there's no over, so that was the reason.

Exactly, at first I thought the 1dB you mean is 1dBr (my bad)... YES, I tried, and it did OVR.

Now you can enjoy the music, even with your setting, still safe for the amp, at the manual it said input max. is 7V ....

The 0.999834 is from the track's peak level that I was listening when I observed the OVR (Lana Del Rey - The Next Best American Record). I assumed if it's past 1.0 then I'd be getting OVR.

And yeah, getting OVRs on the whole album, for example, if I use post-FX. No OVR with pre-FX (still don't quite understand how these two differ, thought they only take EQ into account so I expected them both to show the same result since I don't use any on my speakers).

Am I missing something or am I good?

You can try dual meter to observe it, could be your pre-amp input should be a bit lower.

Oh it doesn't bother me at all as long as I know I'm doing nothing wrong here. Indeed going above 0db is the result here. Thank you for giving me peace of mind

Pre-FX never goes OVR, 0.0 is max.

No problem with your amp.

If you set RME auto-ref on, PEQ/BT will not overload, but you said post-fx, it sounds a bit strange to me .... do not know if it is Foobar problem but it seems not reasonable ...... wish other members can assist you in this matter.....

Was thinking if it could be due to the volume being set to +1db as the manual states I should do if I want the 2V signal for the int. amp.. Dunno though, can't hear any anomalies in the sound whatsoever. Just kinda OCD about this stuff to get it just right once I start fiddling.

May be you try 7dBu again and see the result? (7dBu = 1.734V)
