The Veloce USB-SPDIF Asynchronous Converter

Preliminary info



  • Asynchronous operation, using Streamlength © technology.
  • Isolated input provides for complete galvanic isolation.
  • Works with the drivers supplied with your computer.
  • Direct-coupled SPDIF output.
  • Transformer-coupled AES/EBU output
  • TOSLINK output, just because we felt like it.
  • Operates with 6 V DC input, to allow external supply options.




The Veloce S/PDIF Asynchronous converter is not a high-speed version of the Legato. Anyone who calls it that is going to get erased from the waiting list.
Permanently.
OK, now that we have that out of the way, here are some important differences.

The Veloce has galvanic isolation at the input. As such, it needs a conventional USB cable.

"You mean that cable you sold us with our Legato will not work?"

Yes.

Doesn't that mean it draws power from my computer? I don't want anything that draws power from my computer."

It draws 1.5 mA. If you have a problem with that, tough. Don't buy it. We don't care. Just spare us the kvetching. OK? Thank you.

The SPDIF output is direct coupled. The AES/EBU output is the transformer-coupled one. Plus, it has a TOSLINK output, so people like my neighbor can use it when they download Netflix. And then hook it up to their AV receiver.

"I thought you guys hate TOSLINK?"

We do. We are also greedy capitalists, and need the money. So, call it selling out. We call it "Mo' money, mo' money, mo' money". If you don't like it, then don't use it. OK?

Obviously, it does 96 kHz. Someone invented integer/hog mode, on the playback s/w, so, we had to make something that would handle that. OK?

"Why does it use a cheap-@$$ wall wart, for the power?"

Because we plan to come out with an optional battery charger, so you can operate "off-line", for even more isolation.

"WHEN??? 2017?"

Maybe.
Certainly by 2018.
OK, 2019, definitely.
Yeah, that means 2020.

"How much for the privledge of owning this doo-hickey? Now that the rest of the world has moved up to 192 kHz."

Well, since we are losing our butts, on selling Legato converters, at $500 (instead of the $1000 it really should cost), we are going to make up for it by gouging you guys for


$799.

Such a deal! Oy.

OK, when you order one, you have to specify if you want a coax BNC-BNC cable (with BNC-RCA adapter), or a AES/EBU (XLR) twisted-pair cable. You get one cable, with each unit. And only one. So, chose wisely.

"What if we want one of each? Will you sell us both? How much extra?"

Depends how broke we are, and how much money we think you have! But, yes, we will sell you both.

"Yeah, but what about the clocks? That is what made the Legato special. Is there anything special about these, or are they just some bog standard off-the shelf ones? Because, that would suck, if it did."

Ok, since you asked.............
It does use something, well, not quite "special", but definitely better than bog standard. The Veloce will use low-noise clock modules, that are "off the shelf". If you call non-cancelable, non-returnable, 4-6 weeks lead-time "off the shelf". IOW, commercially available, but only if you are willing to fork out $$$, up front, and are willing to wait.

For this reason, there may be occasional manufacturing delays, beyond our control. It is also why there are no Veloce converters being sold, yet.

"So, why are you announcing them?"

Oh, just trying to make sure there is a market. Since the money is already spent, on those fancy clock modules!
