I dont see a wordclock input on this thing, how does it sync? Its says it does somehow, though.
Thanks.
 
If it doesn't have a wordclock input, then it clocks to the embedded clock signal of the incoming data stream.
 
Yes, it will sync to the embedded clock signal coming to it through the SPDIF connector. Or, set to internal sync, it can be the master.

The ART DI/O is a surprisingly good for the money converter. I have two of them. One thing I did though was upgrade the power supply, which does make a subtle but good improvement.
 
You use your soundcard's control panel to select where the clock pulse will be derived from. If you're using a Delta 1010, for example, go to "Master Clock," and select "S/PDIF IN" if you want to use the DI/O as your clock source (it has to be connected to your S/PDIF input, obviously).

If you want to use a dedicated external clock, then you need to hook that up to your soundcard's clock input, and select "Wordclock" as your clock source. And if you want to use the 1010's internal wordclock, you select "Internal Xtal." If either "wordclock" or "internal" are selected in your soundcard's control panel, then the DI/O will automatically slave to that. Unless you have a good dedicated clock (like a Lucid or something along those lines), then I would highly urge you to use the DI/O as your master clock.

SonicAlbert's power supply suggestion is a good one. If only for the convenience factor, as it allows you to ditch the wallwart.
 
Actually, the new power supply is a lump in the line variety. So while nicer than the wall wart, it's still not an internal supply.

I also experimented with removing the tubes from the DI/O's. They sounded fine that way. The tube is only on the input anyway, not the output (despite what the manual says). What was most noticeable was how cool the DI/O's ran without the tube, hardly any heat generation at all.
 
It's still pretty disheartening that all of the well-published mods that are out there for this thing are all on the D/A side. The most popular mods are done by a company called Boulder Cable, and one of their first proceedures is to remove the A/D section.

I called the guy and asked him if he could do the same mods -- only in reverse and on the A/D section as opposed to the D/A. Lord knows, it could use it. :D

I popped mine open, and saw nothing but a bunch of bigass electrolytic capacitors and cheap opamps eeeverywhere. Still, there's something about the way it sounds, and if you listen, you can't argue . . . there's something to the damn thing.

And I think what people like about it is the clock. I tried the a/b with my soundcard's internal clock, and it was like "I'll be damned. That must be why the audiophile dorks like this thing." It's certainly not all the electrolytics or cheap opamps! :D Or the toooob. I think what we have is a company that accidentally stuffed a really stable wordclock inside a gutted Tube MP ( :D ), and managed to design it in such a way that all the cheap shit they surrounded it with wouldn't deteriorate the sound that badly.
 
So you think the DI/O clock is better than the Delta? Thats really surprising, never even crossed my mind.
Too bad it doesnt have wordclock in, thats its biggest letdown to me.
 
If your soundcard has a wordclock in, then the di/o doesn't need one. What kind of soundcard are you using? I thought you had a 1010 (?)
 
101 yeah... I cant see myself clocking to an embedded clock signal, they just arent as stable that way, always heard that and I kinda beleive it. Makes sense.
I guess I'll see when it gets here, all I really need is another track or 2 for scratch stuff anyway. Sometimes 8 doesnt cut it.
 
Then all you have to do is make sure that your 1010's control panel is set to "Internal Xtal" Word Clock, and your DI/O will automatically slave to the 1010's internal clock.

Or if you want to use an entirely different word clock, you hook that up to the 1010's wordclock input and set the 1010's control panel to "wordclock" and everything will slave to that.

It's all set up in the control panel.
 
The DI/O is fine for scratch tracks, for those moments when you need an extra couple channels of conversion. That's what I use mine for.

As far as clocking to en embedded signal, that's pretty common and I haven't noticed any problems in that regard with the DI/O. It locks up fast and seems quite stable. I do use an AardSync II master clock though, so the DI/O is getting a stable clock from the embedded signal to begin with.
