RME ADI-2 problems?

flail19 · 13th March 2006

Hi. I am not getting anywhere with other forums, I know you guys rule so here goes. First here is my chain. RNP>>>ADI-2>>>>Mbox via spdif cable. After several attempts to lock in the sample rate (I get all kinds of noises such as white noise and crackles and other noise), when I finally get a clean signal the ADI-2 wont keep it after I shut it down. I thought when the clock was set and locked it kept those settings. Anyone else in this boat?

Do you have your computer/m-box set to slave to the clock of the ADI-2? Sounds like that is your problem.

Yes my mbox is clocked off the ADI via spdif and the inputs are set to spdif. To make it clear, I eventually get it to work just fine. But, I end up toggleing numourous times until the noise stops. When shut off the thing never saves any of the settings

.

Thanks.

it saves my settings...
but i have an 002r..
clocks fine...no noise...

check your cables...

did you try the forums at RME....?

I've got the same basic problem....

ADI-2 is the master clock for the MBox. The Clock Source in Pro Tools is set to SPDIF. Playback is perfect and sounds really really good. When I press record enable, all I get is static. On the in put channel with my mic pre, I can hear the mic and then the static builds up like crazy, suggesting a feedback loop? I have a basic i/o routing setup, don't know what it could be there.

Any ideas? Is is a clock problem or a misconfigured Pro Tools? No flashing lights anywhere.....

how are the converters on the ADI-2 compared to the 002????

The A-D's digital output is presented on both a coaxial phono connector and a Toslink optical port, although you can choose different data formats — a front-panel selector enables the output format to be switched between Consumer (S/PDIF), Pro (AES), and ADAT. The phono connector is used to output S/PDIF or AES data: changing the format from Consumer to Pro increases the signal level (from 0.8V to 2.3V peak-to-peak) and changes the status flags to comply with the relevant standards.

Do you have the appropriate format selected?

Also, this could be an SPDIF cable issue. Is the cable you're using a short 75ohm cable?

Also, make sure the AD1-2 is booted up before the mbox

From Sound On Sound review of the unit:

Quote:

The ADI2 is a very straightforward and compact unit, the simplicity (and comparatively low UK price) of which belies its superb quality. This really is a star performer which compared favourably against my trusty Apogee PSX100, as well as the rather nice converters in the Drawmer DC2476 mastering processor. Noise and distortion are completely inaudible, even when working with generous headroom; the audio spectrum is open and airy (especially at the double and quadruple sample rates); and the stereo imaging is three-dimensional and completely stable — always the sign of a good clock — with wide and deep sound stages. The only relevant negative comment I could raise is that the low bass seems a little thin when compared to some more expensive converters — but you have to move a very long way up the price scale before the RME's inevitable shortcomings start to become noticeable at all.

cool, thanx.....

Maybe try not powering down the RME? I had this problem with another AD converter.

flail19 · 17th July 2006

oh yeah. Here's an update. I now have a 002R and all is well.

halfguard · 17th July 2006

flail, i have a 002r aswell. how are you liking the ADI compared to 002 converters????

flail19 · 17th July 2006

I am very happy with the ADI-2. I did A/B comparisons for vocals and acoustic guitar and hands down you can really hear the difference from the 002r converters. When I track drums I run the kick and snare through a separate pre and the ADI-2 via s/pdif. I get very good results.

I have had the ADI-2 for few months now and I can tell you that when you cut the power and then plug it back up, it does keep the last setting used.. The problem is not the ADI,, the problem is your Mbox software, or your recording program.

The Mbox drivers or the recording program is resetting the sample rate everytime you open the program. This happened to me with the Emu card and Samplitude.. Samplitude by default opened up with 44khz. I had to go into the options and tell it to always open up in 96khz. After I did this it was fine,, but it was the shittyyy Patchmix DSP EMU drivers that keep changing the sample rate..

I would question your Mbox or DAW software.

Oh , and I havn't used a Digi002,, but I have tested the ADI against a Lynx One and Mytek 24/96. It beat the lynx one, and was right there with the Mytek, differant , but still just as good IMO.

I had a ADI-2 and sold it. The difference between the converters in the 002 and the ADI-2 did not justify the expense. YMMV.

For future reference if anyone stumbles here, I had this same problem and the issue was i has the "Pro' (AES) format selected in output format, instead of "Con" (S/PDIF).

I think this may actually be the highest-value way to run pro tools unless you need to track many instruments at once. the Mbox2 is basically a pro tools dongle...I clock with the ADI-2, and the whole rig cost less than an 002r.

I will use the Mbox2 pres only when I need a second pair of inputs for something in a pinch. I don't run 92khz but if I did I would use high-end stuff like the HEDD or Lavry. The ADI-2's problem is lack of word clock i/o, but it does have simultaneous coax and optical i/o and you can usually clock with those OK.

If I wasn't smacked-out on Pro tools since v. 4.0 i might get the FireFace instead.
