I donīt know this one you have, so i couldnīt answer this question.
Ops Sorry, i thought this the "naked" version of Teralink X2
But if i look at the chip almost the same (i use the same ASIO driver from teradak and no problem)
The difference only at Regulator, capacitor, pulse transformer and of course layout


about to turn on this device :
- applied external supply first and then plug the USB
- or Plug the USB first and then applied external Supply
Which one do you prefer ?

I had some time yesterday and finally got all parts together to start with the 3.3V shunt.
It is working, but when I connect it to the Teralink, it is not seen by the computer...
I took out the 3.3 reg and the 100ĩf cap, as Oliver did, and connected the negative rail to the switch, where also the neg rail from the 5V shunt is connected. I have a 17R resistor for R1, which gives about 100ma over this resistor.
So it should work, but it doesn`t...
I put the onboard reg and cap back, and it is working normal again, so the chip is still o.K.
Did I forget something? Do I have to take out something else?

btw does anyone know why I cannot use the smilies? Not my day today...

o.k., I tried it a second time, and now it works, strange enough. Soundwise it is ..eh..different. Seems to be clearer, and more detailed and dynamic, but difficult to say from memory. In my experience the shunts need some time to "ripe", so it will improve next days.

But still no smielies possible...

Because my DAC can ACCEPT I2S Directly
Is that recomended to remove those I2S Buffer ?
the place between DAC and "Teralink" is pretty close around 10cm only

Click the image to open in full size.

My Plan is put the "teralink" in the same box, so i can keep the gap between two device as close as possible

I have just swapped out the LT1084 with regulated 5v. I get green light but no sound and X2 is recognized. Then I realized that 3.3v is separate from 5v. Does this mean I need to use another DC adapter for the 3.3v (I cant use 3.3v shunt)? The 3.3v is not powered by the 5v, right?
