Evo sad pogledah.... :whistle2:

Ja sam turio direktno I2s na DAC bez tih otpornika, jel moze to da bude razlog.....da ne funkcionira :guitarplayer:

Negde sam procitao da mora da se .....

The X2 is good IF (BIG IF) you can set your computer to have a low dpc latency so the USB packets get sent on time every time.

There is some software that can show your PC's latency - dpclat.exe - http://www.thesycon.de/deu/latency_check.shtml

Asynch devices don't need to worry about latency so if you can get the signal isolated like John Kenny's design, that's the way to go.

If you can get your latency very low and keep it that way, then an X2 can be just as good imo.

Ako neko razume, bi li mi objasnio :wink2:

BB, jesi skinuo/raskačio ona 4 otpora 50-ak Ohm između DAC-a i CS8416?

A 'bem li ga, probaj... ...ne bi trebalo da su nešto preterano kritični ali imaju neku svrhu čim su gi metili tu di su.

Imaju svrhuAli se njihova vrednost ne moze precizno odrediti bez upotrebe osciloskopa(google signal integrity)prvo trimerom setovati R za svaku liniju a potom zameniti najblizom vrdnosti R..Ima jos nesto Svaki DAC chip ima svoje nivoe kada dostize ditalnu nulu i digitalnu jedinicui to je unutar opsega napona napajanjai to moze da bude drasticno. Na primer 1 kod nekih dacova moze da bude i na 2.7VTi podaci postoje u PDFu za svaki dac chip.Niko to ne postuje a trebalo bi primeniti prilagodjenje nivoa I2S signalaprema specifikaciji.
