Storm D02 + EMU 0404 + Synch Daughter Card

post #1 of 20
Thread Starter 
Will this work? Can the Storm D02 with its wordclock output master the EMU 0404 (with daughter card) as a slave.

This could be the ultimate in a low jitter transport. By running a transport as a slave to the external DAC it has been shown that jitter is greatly reduced. Now imagine that transport is this HD-PC-soundcard, this could be a revolution. Finally reducing the main source of jitter from a PC.

I'm just not sure the clock of the D02 can drive the 0404 ( frequencies compatible?)

Pretty sure it is compatiable.. but e-mail him to make sure.

I guess the issue is the word clock is PLL derived, so this might not be as jitter free as hoped.

Got word that the D02A as master and 0404 as slave will work fine. 44.1 word sync.

That's very good to hear akwok, I guess I'll be buying one of those daughter cards in a bit. I preduct that EMU is going to sell quite a bit of these in the next month.

Can someone explain to me what this clock in clock out stuff is and what it would do on the storm?

Also, what is this i2s input?

www.LessLoss.com

Read through that site, they have a ton of information about sync'ing the clocks of your transport and DAC, and why it is beneficial.

I2S basically separates the clock and data signals which can reduce jitter.

^Thanks Wikipedia!

If you read the LessLoss info, they use SuperClock which is a raw clock signal rather than word-clock which is used on the EMU/Storm. So I am not sure which is better, but it would seem the EMU would have the same disadvatage that a DVD player does. In that a PLL derives the 44.1khz frequency from a 28ghz clock. Correct me if I'm wrong.

I'm really interested in this topic. I'm always on the lookout for ways to reduce jitter when using the pc as a transport and this seems like a good one. Please keep this thread alive!

Just ordered a used emu 0404 off ebay. Will get the daughter card when it comes back in stock at the emu site. Still a long time until the Storm D02A gets here though

if this is properly implemented it could be a huge step in jitter reduction from the PC. This could literally blow away transports costing tens of thousands.

However it could be a gimmick.

I posted in the other source forum to see pictures of the storm to see how this is implemented.

Regarding cables: When connecting the D02A to the daughter card, is it a loop or is it just a single cable connecting the two? I wanna know how many cables Im gonna need to buy.

You'll probably need two coax cables. One will connect the Coax output of the main card to the DAC, and the other will be used to for the word clock sync. However, the word clock could be a BNC connector, so before you buy make sure you get clarification.

Looks like I might have to buy another 0404, as a recent storm killed my motherboard/CPU, and possibly my 0404. Hopefully it's just the analog section

The connection on the daughter card is a BNC connector. I checked the manual on the emu site.

That really sucks about your computer. I'd lose it if a storm did that to my system. Hopefully the card can be salvaged.

Invest in an APC Smart UPS. True, its a lot of money, but I rest in peace knowing that everything in my room is protected.

Or you could splurge on an APC Smart UPS-RT. This runs 100% of the time off battery power. That way you could convince yourself it's an audiophile upgrade too, if you swing that way.
