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

[ShiZo]

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

Nice measurements!

Can you tell if the DPS-2 gave you any performance gains?

I don't think RME make any such claims.

 

[DrCWO]

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.
Nevertheless I would be strongly interested to see the same SINAD measurement without DPS2.

Please let us know if the DPS2 brings measurable improvements. That would be really interesting.

Good to see, but it seems odd to omit the manufacturer's name from the title.

I see that this can digitise RIAA phono. Would it be possible to measure that?

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

But yes, it measures really well.

Can you please remeasure to compare with the normal power supply?

RME ADI-2/4 Pro SE - RIAA mode measurements

Hi here are some measurement of the new RME ADI-2/4 Pro SE in RIAA (phono) mode The RME ADI-24 Pro SE is RME's last addition to their ADI-2 converters range. RME explains that SE means "Special Edition", and they advertise it as a Special, Limited edition, on top of the existing ADI-2 serie...

The dps-2 didn't make a difference last time I measured, but I may do it again for the sake of this thread

 

[Hemi-Demon]

The only dislike I have of my Pro SE is the whine form the stock power supply brick under my desk when the unit is off. It's only audible if everything else in my music room is silent, but it's still annoying for the price paid.

Does this PSU unit operate quietly?

I noticed the same thing and I am very sensitive to such things. The RME DPS-2 is absolutely silent. I believe RME even makes that a goal in the manufacturing process of the DPS-2. I only noticed the noise from the stock PSU when close though, so there could be variance

Both have completely different technology. The stock PS is a switch PS the DPS a linear one with a mains transformer (50 or 60Hz)

Definitely. Can confirm the stock psu is very noisey externally. Luckily, mine was only noisy if I put my head near it. Even being sensitive to coil hum, the dps-2 is incredibly quiet, I can't hear a thing from it. I might be posting the stock psu measurements soon to compare with the DPS-2. When I first got it, I did measurements and it really did seem the same. I concluded that if there was a difference, it has to do with emi and rfi pollution

That's enough for me. Thanks.

 

[Sokel]

We have already seen stock vs DPS measurements and no impact was apparent.
However stock PSU is noisy of it's own sometimes and as what we are interested in is end result, an audible element in our room crumbles the THD+N (the noise part) at ~60's at least.

What good is a -120dB gear internally if it adds noise externally?
So...

End of report.

May think first before posting.
Measured items aren't by far over 10 years in the market so that is not true.

These had been replaced by newer variants since then. The ADI-2 Pro FS R was released in 2020, with current revision (based on a new FPGA generation) being around since 2023, I believe. The ADI-2 DAC FS was most recently updated in 2021 (and I believe there is a similar situation with the FPGA revision being updated more recently). The ADI-2/4 Pro SE, which has a vastly different hardware design from the ADI-2 Pro, launched in late 2022.
