Minidac DIR9001 - WM8740

[Catalin C.]

In urma operatiunii de la http://www.hi-fi.ro/fhifi/viewtopic.php?t=21975&start=15 au ramas cateva componente care puse cap la cap au dat nastere unui mic dac.
Am folosit un receiver spdif cu DIR9001 inspirat de http://pavouk.org/hw/modulardac/en_dir9001spdif.html , dac-ul WM8740 si conversia balansat/nebalansat cu transformatoare. Accesoriul ideal pentru pc datorita izolarii galvanice si la intrare si la iesire.
