Gruesome Artifacts with D/IO and C02 - Page 2

WTF indeed

The ART DI/O is apparently very susceptable to power problems. Over the weekend, turning on a fluorescent lamp wedged mine completely, in a state similar to what scrypt reports. Fortunately, turning off the lamp and power cycling the DI/O took care of it.

It does make you wonder. The ART DI/O is supposed to be pro gear isn't it? Is all pro gear so fickle?

Not really. I have a roomful of pro gear and am not accustomed to these depths of failure from anything but my moo-hanking CPU. One's DAC is not supposed to crash, thank you very nice.

[Edit: One other thing: a pro-level ADC/DAC does not cost $106.00.]

If the clipping is a result of the DI/O's locking ability, then there are mods available to remedy it. Check out the DIOMODS yahoo group for details. I've had to cycle through the sample rates after power interruption, but my ps has never been a problem. The Stancor is waaaay better than the 800mA or 1500 mA units I was using; it's a great purchase. The stereo is better separated, and the highs are more articulate with the STA-5790. ...Hope everything jives better now.

hehe.

Where did you get it for that price, fullcompass?

I may be looking for another DI/O because I'm a fan of it.

Neither does an ART DI/O, once you start modding it...

[Edit Yes, frond Ian, the D/IO purchase in ques occurred at fullcompass. But that was eight months ago.]

In my experience w/yahooooo groups, joining does not mean one partakes of the festive archives. I believe *this* to be the point of departure o' which you input:

http://groups.yahoo.com/group/DIOmods/

In your experience, what search word is going to yield one of the mods of which you type? I tried *clipping* and *lock* but got nothing useful.

Odd to see foonts recommending Hosa cables over the Monster variety, as the former's what I grew up using -- unlike audio hedonist Rimbauds such as rangy-eyed Eric343 (hi, sailor, they warned us about you in philosophy class), who is doubtless jaded beyond redemption. Tragic and yet, somehow, not tragic. Excelsior. On tonight's menu, Human Hair and Our Taste Buds -- When Is Enough Too Much? (*Yoo*-hoo, Hosa Hostess, this opaline-flavored quarter-inch needs a bit more reindeer lobe extract and -- do you mind? -- a touch more minted basilisk (or is that odalisque?), grunt, quack, mmm-bwey-bwey, z-z-z-z-z-z-z-z-z-z-z-z. And now, Greek tragedy. Take my dactyls, Anapest.)

wuzzup scrypt,

when I use the DI/O, using any sample rate but ext. sync causes a bit of fluttering, and/or pops and other noise (sometimes hardly noticeable). I have to use the ext. sync mode to get the cleanest sound but if I don't power up the stereo right, the noise is awful . If this experience has any parallels to your clipping, then ensuring that the DI/O locks onto the signal is key to using ext. sync. mode.

I did a search on 'signal lock'. You're right. there's a lot to sift through, but a more concise explanation of the mod can be found at ->
Craig Fraser's site


I've got to tell ya that I haven't needed to do the mod. If you think it's what you need, tell us how it goes.

Hope it helps!

Sorry, I wouldn't know; I haven't paid attention to Billy Corgan since Melon-shaped Collies Performed Oculatio on Despondent Socket Injury Syndrome Survivors or whatever the moo-cvnt it was dubbed in those days of cello-laden guitar tracks and breathless-yet-throaty vocals.

zoboomofo:

I've never gotten external sync to work reliably -- only 44.1 and 88.8 with CD, 96 with DVD. Why, god, why?

Thanks for the link, by the bye.

Hmmm... I use a Dayton Audio converter, and get artifacts on everything but external sync. mode. It wouldn't have anything to do with my cheap plastic optical cable, would it?

Mr. HappymaN,

I think that the artifacts are to be expected if your source is not a proper cd transport, like mine isn't. It's been a while since I've been in the DI/O forums, but here's what I heard:

If you use the Ext. sync mode, the DI/O will take whichever clock signal (and digital music signal) it is fed as a 'slave' to the cd player 'master'. The signal should pass through cleanly. If you use the DI/O's own clock through one of the fixed sample rates, then the DI/O becomes the clock 'master' to the cd player's 'slave'. An el cheapo cd player won't have the capability that a dedicated cd transport has of "enslaving" itself to the dac. The cd player's signal then won't always agree with what the dac expects and you get artifacts or some other noise (or just a high noise floor).

Which doesn't explain why both D/IOs I've owned refused to read ext. sync with any PCDP, DVDP, converted optical connection, coaxial connection or what grog you. The D/IO will read fixed sample rates easily (44.1 and 88.2 from CD, 96 from a DVD) but will not even whimper softly if ext sync is engaged. A peculiar business, no?

Yeah, the di/o has a reputation on some forums of being finicky with its signal locking ability (especially ext sync). It's been suggested that the di/o's power requirements, the digital cable, and transport may be the factors that decide how finicky it is. Scrypt, it sounds like you eliminated the last two factors at least. Perhaps the mod is something to consider - oh the horror. It can be a tricky board to work at first.

btw, I'm hesitant to do any soldering on the digital board. I seem to always get zaps during soldering, and the components on that daughterboard are quite sensitive to static.
