See those diamond shapes printed on the board surface?
You'll probably find surface mount LSI chips on the solder side underneath them.

Yes I can see them, I think that they might be the DACs aswell but where is the fourth?

Maybe two of them are dual DACs and the third is some other function.
Just guessing without the schematic. If you can read the part number off the chips you could look up their datasheet on Google.

I think one is dual for digital audio out and the other two are for analog audio out!
Btw! I heard once that DACs are used only for digital audio out! Is that true? Are they available only for Digital Optical Out? Or are they available for L/R audio out line?

Hi oszkar,

There are 4 DACs on the board now I've seen them one of them is a small rectangular one and states for sure IC and number, I don't remember quite 801 I think, the rest are the ruby shape ones that state IC as well but different serries!
