RME ADI 2/4 (with DPS-2) Measurements

[DrCWO]

The RME ADI-2/4 Pro isn't that old. Released maybe 2-3 years or so ago?

Maybe this is interesting information. I found it in the RME forum:

Maybe you should make an attribution to ramses who made an effort and compiled the info, or at least provide the link to that thread.

Absolutely correct, thank you for the hint

I tested SINAD at every ref level to see the performance difference between them:

1dBu:

7dBu:

13dBu:

19dBu:

24dBu:

Thank you for your contribution.

This was loopback from output to input I guess.
If yes what we see here is probably the performance of the ADC as DACs measure normally better.

Overall, this unit shows better measurement results with a high-performance external ADC (AP or Cosmos ADC), since the one in the unit does not have top-end specs (SINAD 119 dB) and follows the AES17 standard method. See my post.

Using the multitone analyzer app and a basic loopback setup to measure the ADI 2/4 SE PRO with DPS-2, nothing special like summing or mono. These are the measurements I got running -1db play gain and -1db analog output with both the ADC and DAC output set to 24 dBu

Can anybody tell me how to get a dark background for charts. I can change the color of the measurements but did not find where to customize the background.
