> Remote Remap Function: I'd love to be able to cycle through the DA Filter on the fly.
> Some tracks are better with different filters

The remappable keys on the remote control can recall setup 1..9.
Store the different DA filter settings to i.e. setup 1-5.
Then you can remap the remote control to recall 4 out of 5 filters as you need.

Please note: I read somewhere that the human brain is unable to remember sound differences over a few seconds.
So you need to perform quick A/B tests between mainly two settings, before you compare between another set.
So the 4 remappable keys should be more than enough to compare your favourite settings with i.e. NOS.
Best is if you get assistence from another person and perform a blind test otherwise your brain works in a way that it has already certain expectations if you know what you select and this will adulterate the results towards how you wish they should be.

A toggle function to change between all settings would not make sense, takes too much time to change between settings that are not close to each other.
A toggle forward and backward would also need 2 keys and then you could also only quickly A/B between DA filter 1+2, 2+3 and so on but not between 1 and 3 ...
I think it's perfect like it is.

Once you tested everything I am pretty convinced that you will stay anyway with one setting.

My main feature request is a jitter measurement, similar to bit-perfect tests but showing jitter in ns instead. That would help a lot in setup and when optimizing sound quality.

"Out of this world"...does that mean I am an alien? :-)

I was thinking something like this: count the master clock pulses and compare when a sample is handled compared to when its supposed to be handled (determined by the original file and sample rate). Totally in the digital domain, don't bother with clock jitter since it won't be much anyway with a femto clock.

Magnus H, any further post of yours here on this jitter topic will be deleted as you are hijacking this thread. Same for others, stay on the topic.

The 'switch off' voltage is a fixed hardware setting and can not be changed by firmware. I recommend Li-Ion batteries with included protection, they solve both over- and undercharge problems.

RME, thank you so much for ADI-2. I don't know how you did it, but you nailed it spot on to my desires (and I had to use a bunch of other solutions like audio hijacking on computer, VST equalizer etc, which is very bad and hardly usable). However, there are a few improvements that I'd like to suggest:

1) Increase PEQ bands to at least 7 or 8. Reasoning behind this is that when you do basic corrections, 3 narrow bands and 2 wide bands (bass and treble shelfs and 3 peaks, for example) will be good. If I need to dig deeper into correcting headphones, I need to cut out certain ringing frequencies, and there are at least 4 of them normally, so I barely fit into what ADI-2 DAC offers in terms of PEQ and there's no bands left for possible timbre correction, but more bands would be just perfect.

2) Introduce auto-off or sleep function, which will turn the device off after prolonged non-usage. For example, it could turn off after X amount of hours sitting idle (no buttons pressed, sound level below UFL). It heats up quite well after a few hours (nor overly so though), and it would be good to have it turn off automatically.

3) Make IEM output prioritized over Phones when IEMs are inserted over Phones (or make the setting like this). Reasoning is that I have my headphones plugged in all the time, and sometimes I plug in IEMs, and now I have to plug headphones out before I do it, and then plug IEM's in for the unit to automatically switch to IEM output and switch settings.

4) Improve automatic source selection. Current implementation voids Auto setting of source if there's lock and sync on coaxial input, so once I plug in anything working to coaxial - it's done, no Auto source. It would be nice to have it automatically recognize that even though there's a device plugged in to coaxial (or optical), there's UFL signal coming from it, and if there's meaningful signal coming from USB - select USB automatically. For now I use manual selection of source and it kind of defeats the purpose, but works.

cool idea.

Would it be possible to adjust dynamics in DSP, which would basically work as volume except non-linear:
- Let X be the amplitude of a frequency
- Let Y be the dynamics, expressed as percentage (default 100%), min 75% max 125% (or something similar)
- The new amplitude would then be calculated as X^(Y / 100.0)

Room, walls, speaker stands etc can all affect dynamic in different ways, and this could be a way to compensate. Not sure how to implement it in a convolution/DSP engine though which I assume is used inside the DAC. If combined with PEQ (if performance is enough), PEQ should be applied first.

Thanks to the RME Team for the Fine Product Support.     The Firmware installation went seamlessly.   

Viele Dank

I would need a new action with the remote...

It’s about the « Width » setting in « Line Out ». I think that if I set Width to -1,00, the Left and Right channels will be swapped ? This is exactly what I need, but not permanently !
I would need to swap left and right stereo channels occasionally each time I press a button on the remote. Or Better, set Width to 0 using a button, and to -1 using another button. Otherwise, using only one button, I will never know when the left and right channel are swapped or not...

Do you think it would be possible to add this feature ?

Thanks.

[EDIT]

Well, maybe I can already do that loading 2 different setups assigned on 2 buttons... I’ll try that !
I hope that will work « on the fly » when the amplifier is still turned ON ! No problem with the sound in my HiFi speakers ?

... PERFECT ! It works according to my needs.

Thanks for this great DAC ! Until now I focused on the equalization... what is most important.

I would buy a black faceplate for my Pro FS

Fast output channel switch in volume screen.
1. L,R, Both channels.
2. L sent to both outs, R sent to both outs.

Hi
I like the ADi-2 Pro fs. Awesome tool and great sound.

I want to use it as a measurement soundcard.
So my question:
Would it be possible to allow
1. Backup/restore of the device setups to/from the PC via USB
2. Remote change of settings, (including Volume, Trim, Ref level, Mode, EQ, Filter, Bass/Treble,...) through some API, also via USB
????

This would allow more automated tests.
And could also help integrating the ADI-2 Pro into a studio automation.

I would love to have this functionality too, particularly item 2.

For me it would be also nice scaled to "dBu", so you know about the maximal levels. IMHO it may requires an additional ADC, while the ADC runs at a selected attenuation...

Jas0_0,

The Treble Control freq is adjustable, but only up to 10khz per the Manual.   The NOS filter is best linearized at 14.3khz.   You COULD give your proposal a try, but your correction really wont be Spot On.

Curt

Jas0_0,

Ehhh...if you were in a Labaratory Test environment, absolute accuracy would be a large issue.  In the Home?  We tend to get away with Murder, and a less-than-perfect correction might just be fine.  10khz is a great frequency to ADD a bit of "Air" to an otherwise closed in recording.

In Terms of Firmware Revisions, an Automatically Set EQ for NOS, and Slow Filters might be helpful to some.   It would need to be Sample Rate dependent however.   If I recall my data properly, High SRs don't need such EQ Correction.

Curt

Jas,

If you have a helper, try to do a genuine Scientific, Level Matched, A/B/X comparison.   The differences are SO small!

Wife...Girlfriend...or perhaps BOTH can try to test your real preference. But not in "weird way"

I'm locked on plain, old "Sharp" here.

*Somewhere in this Forum, I laid out a Procedure in "Set Ups" to ensure that you hear ONLY Filter differences.  Nothing else.  Lord help me find it.

* Here ya go Jas!

@RME,
please turn off the ADC's (AK5574) internal highpass filter by default. Since it is operating only in the lower sample rates (<=192kHz) and is off, by chip design, at higher rates anyway, it just adds confusion with very low frequency electrical measurements.
Plus it would allow the option of shorting the input caps (at owner's risk + loosing warranty, of course) to actually measure DC values....  making the Adi-2 Pro a fully DC-capable test-rig ;-)

May for measurement proposes, a diffrrent hw with real dual (isolated) chip adc would be my favorite and some nice hw notch too ... IMHO this would be different business and may not a RME target..

I second this request for the ADI-2 DAC.  While auto-off or standby may be undesirable in pro audio applications, IMHO it is an extremely useful and environmentally friendly option in a consumer/audiophile product.  For example, I have powered speakers and a tuner that auto standby, so I don't have to keep pushing buttons every time I walk away for a while.

Can you pls describe the purpose ?

This can already be done with the PEQ for frequencies of 200 Hz and above. Set filter band 1 to low shelf and filter band 5 to high shelf and adjust their frequency, gain and Q to your preference. If you want simultaneous changes, you can save your preferred tilt curves in EQ profiles or setups.

If you want it as an additional feature, it has to be squared off with the DSP limitations and you will probably have to forego using filter bands 1 and 5 for other applications.

I posted the link to Ken Rockwell because he has some good graphs to show that this is different from B/T controls and more like a house curve. After all, Peter Walker's Quad was by no means audiophool BS.
