Today I removed the jumper, but found out that it was there for a reason. Removing it resulted in the exact same problem as danielkol was having with his DAC. I had to put back the jumper in order to get the DAC working again. Although the connector ground and DAC ground are connected, it still is isolated from my CD-transport. The spdif output of my CD-transport also has a isolating pulse transformer as any spdif output should have.

Strange. It is working just fine in my own setup without the jumper.

As a prospective user of this DAC (I'm in the second buyer's group) I'm very interested on everything that is being written in this thread. Very useful information here, Thanks Corpius, Algar_emi, danielkol and all of you who are contributing.
Anyway, it wouldn't hurt if Quanghao himself entered more often in this thread to clarify or explain some points about the design or settings of the DAC which might seem obscure or puzzling to the final user. He's probably very busy at the moment, but sparing some minutes now and then to post here would be very appreciated, ( Speaking for myself, but I expect that most of you will see my point )

I wonder if I can use 195 ohm series resistors and 100 pf to ground at the output off 9018. Then I will send it to a circuit with 220 ohn series resistors and 39 kohm to ground. Looks like ess 9018 is oscillating. There is 200 mv ac out off 9018 and 77 ma ac out off analog stage and no signal. What is neccesary for voltage out circuit ?

Thanks
Marcus,

I've been out of town buried with work. Unfortunately, all I was able to do was take it out of the box, look to make sure everything was there, and that's it. I've yet to hook it up! Sigh...

As soon as I have a chance to spend some time with it, I'll report back.

Steve

hello quanghao.

Hi all,

a question to the mains power fuse. Every week i have to change my fuse. First i had a 200mAT.
Ok, that's a bit low. But 220V/5 = 44W. For running this should be enough.

Now i replaced it with 400mA = ca. 88W. And it's the same. Once a week it burns down.

Which Value do you use?

I'm using a 1A slow-blow fuse. That's what I had lying around.

What's the rated power in watts of his DAC in normal operation?. Anybody has measured it ?
To blow a 400 mAmp. fuse at 230VAC it takes more than 90 watts. Isn't that a bit too much, even considering peak inrush currents at startup ?.
