Agree and understood, this requested feature is not a must :-)

User should observe the output level safe to downstream equipment.

10 band parametric EQ (not included bass/treble)

I just searched and saw nothing by MC in this thread.

Confirmed by who?

No problem. This is why we need to check.

If it is a general user commenting or official word by MC from RME.

Could really low Q, as low as 0.1, be enabled at least for shelf filters in the EQ and bass/treble?

The use case for this would be to set a constant, slow roll-off that does not actually flatten out in the audible range. Q 0.5 is still too steep for that.

This has been discussed before, more than once actually. It's impossible to do with current hardware.

I'd have to suggestions to contribute:

1. Either support for de-emphasis at higher sample rates as well or consequently disabling that function as currently, it doesn't seem to have any effect at higher ones despite the changable setting as elaborately described here, which is somewhat misleading.

2. As we have two meters per channel for the level, it would also only be consequent to have the same for the spectrum analysis. One could have optionally separate screens for each channel OR (non-exclusive) use different colors for the left and right channel with a mixed color where the sum level overlaps to effectively represent both on the main one.

Thanks for the reply, but a pretty pithy plea, considering that quite the opposite is true.

While I also only know 44.1 kHz as a sample rate of commercial pre-emphasis use (mostly on CDs, but also some LaserDiscs and DAT from what I've read), Benchmark Media contradicts your general statement as they list not only 44.1 kHz but also 32, 48 kHz as well as 96 kHz as supported sample rates for automatic de-emphasis in their manual of the famous DAC1:

Besides that, you're missing my point, being that the setting on the ADI-2 devices doesn't show any effect on higher sample rates. Either that should be fixed for the sake of (theoretical) compatibility at least just in case there is any higher one ever to be encountered with pre-emphasis or consequently simply grayed out if there should be no (hardware) support for whatever reason, rendering this option inapplicable anyway.

"Herr Athea, setzen, sechs!"

At first: neither do I understand your harsh tone (which could also need some de-emphasis by the way) nor your continuous misinterpretation of this issue.

Risking to feed the troll - so is Benchmark a "crap hi-fi manufacturer" now? Together with RME, I'd rather say that they are one of the most professionals around and deserve a little bit more respect. Also, you don't seem to he too familiar with the métier as then you can count in ESS - the chipset manufacturer himself - as laymen as well, since they state de-emphasis support at multiple sample rates also.

From any specification, even when only stating 44.1 kHz, one can hardly extrapolate that no source could ever come along with pre-emphasis at a different sample rates.

In fact it does, should the de-emphasis not be supported on a given input sample rate.

That is what one has the "auto" mode for. However, the "on" setting is supposedly an override function, hence it makes no sense for it to act differently depending on the input sample rate. In case of missing flags one of course has to fiddle around manually which is the whole point of having this (great) option (not that this general issue would have anything to do with a specific sample rate). If not supported anyway, "on" shouldn't be an option in that moment (seems logical to me at least).

No, despite its general verbosity, that specific part is not covered by the manual which I consulted first, no worries.

Let's wait for MC's reply who will hopefully follow up with his usual technical, highly respected expertise. After all, this thread is for suggestions and not about arguing about the proposition to begin with.
