> Here comes a small update with issues that were found after the last firmware update (https://forum.rme-audio.de/viewtopic.php?id=34364). The ADI-2 DAC series changes from DSP48 to 49, the ADI-2 Pro series from 112 to 113.

Thanks for the update! I'm installing it right away.

Edit: Now corrected.

Volume is a crucial setting that needs to be always available. In case someone changes it unintentionally it is easy to set back, other than the myriads of options that child fingers could screw up. In that way it makes sense to have the same situation/handling on the remote as on the unit.

I still got 3.0 in English

You wrote 192 kHz, but most probably meant 768 kHz? It works here as expected. You must have overlooked EQ or BT still active, for example EQ on the Analog input (hint: Crossfeed alone can be active on 1/2 and 3/4, even at 768 kHz. But as soon as an EQ is activated on any of the three paths both outputs loose Crossfeed).

Not on my unit, with 113. I can enable all and any FX, this never happens. But your pic tells me that Crossfeed is not normally disabled (), but greyed out. That means you are in DSD mode.  Analog Input DSD Conversion is set to DSD, right?

Edit: I will try later if this is a new bug. It might have been introduced in 112 already.

Ah, yes, you are correct! I have also recently experimented with dsd-recording! The analog input conversion was set to DSD and when I changed it the issue disappeard!

But still a bug I guess, but maybe an old one!?

I don't think so. volume interval is not constant. on the low volume end it doesn't jump by 0.5.

Hi, I am calling up the RME USB Flash Update Tool (Windows 10) for an update to the latest version for the ADI-2 DAC. The Update Tool lists as the New revision: USB 78, DSP 48 with the programming stauts Up-to-date (As-is on the DAC). Any reason as to why the Update Tool is not offering USB 78 & DSP 49 as the new revision? Thx.

Just updated my ADI-2 Pro FSR BE to ver. 113 and the +-12 dB tone control in the PEQ works great!
Well done Matthias & team!

The possible reason is the FUT file you have is the former one. Everytime when there is a new firmware release, download the latest one and run it.

The FUT is not a software doing the over the air update, it is an individual tool itself, though bears the same filename, the readme file is different at each version after you unzipped, it carries the new firmware changed items in it.

If you want to keep the old file, rename it to a different name, such as FW Vxx/yy dd/mm/yy.

Wrong one. Each version has only one "intention" for the DAC:

• December 24th 2021 updates DAC to FPGA 66, DSP 46

• January 20th 2022 updates DAC to FPGA 78, DSP 48

• April 11th 2022 updates DAC to FPGA 78, DSP 49

"Individually"? "Only" would be better.

Run only the file from April 11th 2022 for an actual update, forget all other.

- B/T changed to +/-12 dB. I have to confess that I had a hard time to accept this change, and just hope it doesn’t backfire. The former way of handling it was perfect for me, +/-6 dB does not screw up the sound but allows for a quick turn adjusting the Bass and Treble as the current tune needs it.

I wonder if a user survey was conducted to make such a change?

Did you change to Multichannel mode? UAC-2 works better in Stereo mode.

Yes, WASAPI Exclusive works on stereo mode as 32bit only

I like to use SPDIF using UAC2 as with the mentioned 25...200kHz SR range O:(

Reading page 6:

When used as USB interface, the Class Compliant UAC 2 mode can be set to Stereo or Multichannel. Multi-channel mode turns the ADI-2 Pro into a 6 channel (Analog 1/2, AES, SPDIF) record and 8 channel (Analog 1/2/3/4, AES, SPDIF) playback audio interface, that even works as
iPad front-end up at up to 192 kHz sample rate. In stereo mode sample rates up to 768 kHz are supported, for high resolution recordings or PCM, DXD and DSD record/playback

This means on MS Windows UAC2 as above and should be mentioned & fixed:

- Maximal SR on MS Windows is still on year 2022 384kHz!

- Multichannel Mode is now obsolete?

- SPDIF using UAC2 as with the mentioned 25...200kHz SR range?

Cheers Hp

Well, thank you for the link! It explains all O;)

I did not know that, as this in year 2022 still exists. In words the document at page 6 is than false as mentioning working .

Keep in mind that the UAC2 driver MS (as from Thesycon) is a feedback driver (using clock control) with limited implementation(s).

So one should explain, how a 25...200kHz on SPDIF gets data as 44.1/48....192kHz SR  transferred

Bug:

Hor. Meter “Post-FX dBu” shows 3 dB too low level for PH 1/2 output.

This is the case even with the option: Mute v. TRS 1/2 = ON, so Line Out 1/2 gets muted with headphones plugged in, so PH 1/2 is the only active output.

Hi Matthias,

I have just tested it e.g. by connecting two headphones on 1/2 and 3/4 and setting Mute v. TRS 1/2 = ON.
To my opinion the level meter for phones 1/2 is working for this use case. After switching the standard Mains off by clicking deeply on Volume and also turning the linked volume off the display header for 1/2 shows the following during a change of the Volume:

Volume Main 1/2
Low-Power (Auto)  - Phones

Additionally the volume of both Headphones 1/2 and 3/4 can be changed after clicking softly on Volume.

Ok, now I have made a picture of the Headphone 1/2 volume (- 45 dB) and additionally of the switched on Dual scale for pre and post FX dBu:

I thought the problem is that the big number is only able to show the volume of the Mains 1/2 but not of the Phones 1/2 if the Mains are switched off. Apparently this is not the case.

However I don't know if any of the values in the scales below are matching with the -45 dB above.

Is there a little mistake in the DAC’s manual page 21 and 58?

“SD LD (only AKM)” - isn’t a filter with this name available on both, AKM and ESS versions?
I don’t have a DAC to check.

At least it’s there in ADI-2/4 Pro SE, which is ESS.

265 / 117, explained here:
