Ihave had one of these for about a year as the main converter in my domestic hifi set up. I have been very pleased with it as it does everything it should without any trouble. I occasionally play about with the settings but in all honesty it hardly gets touched. I haven't updated the firmware at all and I suppose I should. The question is to get from where it is to the latest version do I have to do each upgrade in turn or will the latest upgrade contain all the previous ones?

Regards

I'll be honest Kais, I don't know whether this was a go for it or not, so I did on the basis that I could always do a factory reset if necessary. As it is it tells me it has updated the firmware and who am I not to believe it. It all still works and at first try I can hear absolutely no difference. I don't understand what you mean about automatic sample rate switching, could you explain that bit further.

Thanks

Martin

OK, I am getting digital signals from an Innuos Zen via USB or a Cambridge CXnV2 via SPDIF , both I think at 48kHz. Personally I don't think anything higher makes any difference, Nyquist and all that, but even if it does my hearing, normal for my age, rolls off quite nicely after 8Khz so top end signals are becoming a memory. Thanks for explaining things, I'm not certain why anyone should have any difficulty with firmware updates, the printed manual and on-line info are plain enough, even if the actual process doesn't quite follow the printed manual.

Best wishes

Interesting, it appears to apply to Windows users who are also using the computer as an audio source, I am not so I don't suppose I'll have an issue, I certainly haven't detected any signs thus far. I do fail to understand, apart from this specific matter, why you are warning people off updates. Are you saying that for domestic hifi use the updates are unimportant and make no difference, or what may I ask?

Like with all firmware or driver updates from any manufacturer they can cause problems, even though only for very few users. If you use this device for professional reasons (making income based upon) then the usual recommendation is to be conservative in your updates, unless you deem the updates very important for various reasons or have a backup of some kind (say, another PC and/or device). So, if an update fails you still need to have some way to fulfil your professional obligations or taking on new projects.

I use my ADI-2 mostly for home hi-fi but sometimes work related (video calls), but I do update drivers and features from RME as they contain bugfixes and new features as RME are very good at this. Similar for my Fireface UCX II.

Thanks Kais, I understand your view. I ran the updates on my PC which is not used for any audio purposes. The DAC is working fine, if I could get the rest of the network to behave it would be good.

Thanks for your help.

There is no driver, the ADI-2 Series converters are only working as Class Compliant USB Audio interfaces for Mac OS. You can use the FUT to update the internal firmware, but if it already has current firmware then nothing changes.

I am trying to get on the same 'page' in terms of ADI-2 firmware & downloads such as DigiCheck. Between the ADI-2 manual instructions and RME's Website & Support/Forum assistance, one may get slightly different how-tos.

To update ADI-2 Pro FS running on a Mac Studio M1 Ventura (brief steps)

The ADI-2 Pro FS is powered off.

1. Boot Ventura to Safe Mode (I guess it is called).

2. Go to Setting and Allow RME to modify its core. Then on to Security, I have never seen the Allow reference to RME or ADI. The general Allow was checked.

3. However I continue on my Mac.

4. Mac is still in its primal mode.

5. ADI is still Off.

I am not certain which way is the correct way (Step 6 on)?

6. Boot Ventura.

7. After booting to Ventura and it is alive, I power up the ADI-2. However ... should I Power on as normal or should I hold both the top small knob and big Volume Knob in, then Power On? When should I release the two maintained knobs? Just after Power up or when the first display occurs?

So you see the input signal, which is expected. Did you open the Input Selection window to set the channels that you want to monitor (right click on the respective instrument)? With the ADI DC NG can not access the playback data directly, you need to use the ADI's newer Loopback function - I assume that is why you want to update the firmware.

I have a ADI-2 PRO fs. Showing my lack of RME 'meaningful understanding', how does ADI DC NG relate to the ADI-2 Pro fs?

These are driver installation steps, and there is no driver here! Nor does the readme of the FUT tell you to do this.

At least from my perspective, the ADI-2 PRO FS update instructions are not very clear. For someone that knows the ADI product line, I am sure they are crystal clear. I understood that was the required steps to update the firmware. I do understand what you are saying though.

Start your Mac fullly normal, connect and start the ADI, then start the FUT. Easy as that.

That is no doubt easy moves. Why are there so many sorted update instructions for the ADI-2 Pro FS running on a Mac using Ventura or Monterey?

In summary:

1. I am not clear about ADI DC NG as related to my ADI-2 Pro FS. Please explain further or point to a related link.

2. 'Start your Mac fullly normal, connect and start the ADI, then start the FUT. Easy as that.' I will certainly do this. I understand this, I was somehow mislead by not fully understanding the different Website instructions. RME may could improve clarity on the procedures since there are several. Please point to the related link.

This is most easily detected when the volume changes are displayed as 0.5 dB steps. In this case, the jumps are 1.5 dB.

However, it is also detectable during quicker volume changes, i.e. quicker rotation of the knob, but in this case, the jumps may be of different magnitude.

I report a similar issue on my (non FS) ADI-2 Pro running the latest firmware 183/88. The jumps are erratic but very frequent, happen even when turning the knob at very slow speeds, and can also go backward.

1. Your encoder is defective inside and causes heavy bouncing, means multiple signals instead of one when turned one step. We think this is not the case. There is an anti-bouncing circuit in the unit, and if so severe that this one fails you would have constant problems with the encoder.

2 has been addressed in the latest firmware update. The treshold of detecting a faster turn, and thus change to quicker and bigger steps, has been raised a tiny bit. Most users will not notice the difference. But if you try to move from -45 dB to -40 dB and arrived at -35 dB although you did not turn the encoder that quick, the new version should help.

Regarding 1, the notches are clearly individually recognisable at low, medium and high angular speed and the indicated level changes follow them tightly, i.e. there are not many or even any unintentional level jumps that cannot be explained by 2.

Regarding 2, I assume, this can arise from the encoder not being settled in a notch and either bouncing a notch forwards or backwards if the grip on the knob is insufficiently tight or after letting go of the knob. Since the resulting acceleration might be greater than the acceleration for the intended volume change, this could indeed lead to relatively large volume changes that can go both up and down.

Hallo,

ich habe weiterhin die komischen Rckwrtssprnge beim Hochdrehen der Lautstrke

Firmware 90, ADI-2 pro, balanced mode, USB mode , EQ off

will die Lautstrke z.B- von -40 hochdrehen dann spring es zu -58 zurck, dann geht es etwas hoch dann wieder zurck usw. Habe ein kleines video aufgenommen, kann es aber hier nicht posten.

Kann ich es per Mail an den Support senden?

In the menus, turning encoder 2 sometimes does not change the setting as it should, e.g. after turning encoder 2, the indicator remains on original setting. Changing of the volume in the I/O menu, leads to similar jumps as when using the volume control.
