Topic: How to connect adi-2 DAC FS to adi-8DS MK III

Hi,

I’m currently using an RME HDSP AES card in my PC connected to an ADI-8 DS Mk iii converter which is working great. I’m now thinking about adding an ADI-2 DAC FS for its headphone pre-amp and ability to add Harman corrective EQ and crossfeed, and reference quality conversion for playback on my monitors.

I am just wondering how they can be connected and what this would look like in Total Mix. Any tips or experience with this setup are greatly appreciated!

Regards,
Maarten

Re: How to connect adi-2 DAC FS to adi-8DS MK III

Proper clock sync via AES .. PCIe card clock master, ADI-2 Pro Slave via AES in, wc not needed.

1. Connect via AES ...
2. In TM FX control room assign Main Out  to the particular AES output.
3. TM FX: configure your preferred submix for Main Out.

ADI-2 Pro: use preamp mode (from memory)
-
- connect to PC via USB to make it manageable via ADI-2 Remote
- install MADIface driver
- upgrade to the latest firmware
- Manage over display or ADI-2 Remote

How to integrate ADI-2 Pro into your setup, see my blog:

Re: How to connect adi-2 DAC FS to adi-8DS MK III

No point connecting the converters to each other, connect both to the card individually and assign channels in the DAW and Totalmix accordingly.

Do you mean me? That was not my proposal / intention.

I would - like you - connect this way:

PC---PCIe----HDSPe AES--AES x/y----ADI-8
|                                 \---AES x/y----ADI-2 Pro FS
| USB                                                      |
|                                                             | For remote control (ADI-2 Remote) and Firmware upgrades

Hi thanks for your reply but the ADI-2 DAC FS does not have AES in I think? Maybe you were missled by the topic title so I now changed it. I did say it in the message already. I’ll check out your blog though.

You are right, I misread and kept it then wrong in my mind.

Thanks for your reply. The ADI-2 DAC FS cannot be directly connected to the AES card I believe. So it would have to go via the ADI-8 I would think. Probably via ADAT? Just unsure about the options to setup for that and what it would bring me in Total Mix.

Re: How to connect adi-2 DAC FS to adi-8DS MK III

Well you would get the signal straight to the ADI-2 DAC FS and then you would use the volume control of the ADI-2 DAC FS anyway.

I assume that the first two channels of the ADAT stream would be used by the ADI-2 DAC FS.

So you most likely have to use the first two AES channels of the HDSPe as Main Out and these two channels could perhaps be routed to the ADAT output, details see manual.

That’s was my thinking yes and I am already using AES1+2 as my main outs so that would work. If just a copy of that would be used by the ADI-2. I’ll need to further check the manuals indeed. Was just wondering whether anybody had any experience with this setup and what to take care of/look out for, etc.

Do you have the devices already there? Should not take too long to try it out.

I have been using the AES card and ADI-8 for years, but now asking these questions to see if I want to add the ADI-2 DAC FS wink

Re: How to connect adi-2 DAC FS to adi-8DS MK III

The pro version would give you more flexibility, also useful features like AD, SRC, routing modes, two DA converters, the possibility to connect two phones or balanced phones or to run monitor and headphones in parallel.

The SPDIF input of the DAC is AES/EBU compatible, you just need a suitable cable. You can't selectively route individual channels from AES to ADAT on the ADI-8, much less with Totalmix.

That said, the ADI-8's patch mode will in fact allow you to send AES in to ADAT out, which can then go to the ADI-2, but only for all 8 channels (of which two will be used by the ADI-2). You will thus be able to send AES to ADAT while using AD and DA via AES....

But direct connection to AES is probably more useful.

Re: How to connect adi-2 DAC FS to adi-8DS MK III

OK, I do not have a complete overlook on what‘s already written here.

Still, just a little hint that might solve the whole thing I guess:

ADI-2 DAC‘s Coax In can take an AES Digital signal, no problem.
Up to at least 5 meters length a standard fitting adapter, XLRf to RCA will do, nothing else needed, not even 110 or 75 Ohm cable.
The adapter’s cable should preferably be balanced, not coax, see (*1).

If the additional ground connection causes a ground/hum loop (might happen), simply cutting the screen on the RCA side will solve that.


(*1) REMARK:

Opposed to analog interfacing, the best AES to RCA pinout is:
XLR 1 –> screen –> X (RCA not connected)
XLR 2 –> wire1 – > RCA tip
XLR 3 –> wire2 – > RCA case

On analog cables screen is connected to both XLR 1 and RCA case.
This does work too with digital, but the additional ground connection can introduce hum by building a ground loop.

If the adapter is built with balanced cable, cutting the screen on the RCA side solves this and usually is a simple task.

With coax cable cutting the screen on either side is no option.
Sometimes it’s possible to cut the link between screen and XLR pin 1, while leaving XLR 3 with screen connected.
This would work too, specifically for short cable legth.

Thanks for that info. You are talking about the ADI-2 Pro FS R Black Edition then I assume?
I shortly looked at that one as well, but it was quite a step up in price and I wasn't really in need for an ADC as well at this time.
I was also kind of intrigued by the special IEM output of the ADI-2 DAC FS.

However, I wasn't aware that the ADI-2 DAC FS could not do speakers AND headphones at the same time. Would be kind of annoying to have to switch that device every time I want to switch from speakers to headphones. Because I typically do any switching on my monitor controller (like mute or select speakers e.g.).

Thanks for your reply. Are you saying that I could connect an AES out from my HDSP AES card to the coax input of the ADI-2 DAC FS? I was not aware of that. Need to look into which cables I would need for that then. Because initially I was indeed thinking of using a duplicate of the AES1+2 I'm sending to the AD-8 via the ADAT patch mode, to the optical input of the ADI-2.

Interesting, you just came up with the same answer as RME support and are more specific on the cabling. I wonder if I could order a cable at Thomann like that. My soldering iron has not been used for a while wink.

If you have one, and have the parts, use it.
XLR and RCA soldering is no rocket science, more like the basics.

Maybe cross check with manual, RME or KaiS.
This was from memory.
I know that only one DA chip is in there, so there were a few restrictions compared to the Pro model.
Sorry, I do not have the time at the moment to investigate on this topic.

Also worth to know that the ADI-2 Pro (FS R BE) has reference levels found in the studio, where the ADI-2 DAC FS has slightly different ref levels and cinch outputs with even less output for HiFi (but unbalanced as well).

For studio the ADI-2 DAC FS would of course be sufficient as well, but I regard the Pro as the better suited more round product, finally topped by the additional features of the ADI-2/4 Pro SE.

If you want take a look at this sticky posting here:
https://forum.rme-audio.de/viewtopic.php?id=32506

Also interesting is this Excel that I put together so that you see the different volume / reference levels of all models.
This gives you also a good overview about the feature auto ref level, how large those ranges are.
For the ADI-2/4 Pro SE largest because of the even 5 ref levels (1 more) that it supports:

Re: How to connect adi-2 DAC FS to adi-8DS MK III

On ADI-2 DAC speakers and headphones can stay connected at the same time.
Switching between both works by pushing the Volume dial for 1/2 second, a button on the IR remote and the Remote App.

Each output has it’s own full set of parameters, i.e. different volume, EQ, crossfeed, etc.

The only thing:
You can’t run both at the same time (with individual settings), but this doesn’t make sense anyway, as you cannot listen to both at the same time either smile


Finally: buying cheap (not exactly true here) means buying twice - you should seriously consider ADI-2 Pro if there’s a chance you might need it’s extras in the future.

Congratulations, I think that's a good decision. If there are any questions about the implementation, please feel free to ask.
Otherwise, just tell how it went.
