Pojačalo NAD C 399

Kao novi vodeci model NAD-ove klasicne serije integriranih pojacala, C 399 HybridDigital DAC pojacalo podiže NAD-ovu predanost trajnoj vrijednosti i zvucnoj kvaliteti na potpuno novu razinu. C 399 koristi NAD-ov Hypex HybridDigital nCore sklop koji je do sada bio dostupan samo na pojacalima Masters serije. Njegov digitalni dio izgraden je oko 32-bit/384kHz ESS Sabre DAC cipa koji se koristi u NAD-ovim hvaljenim pojacalima M10 i M33 Masters serije. C 399 je prvo pojacalo koje ukljucuje najnoviju generaciju NAD-ove tehnologije Modular Design Construction (MDC). MDC2 korisnicima omogucuje dodavanje dodatnih modula koji pružaju funkcije kao što su BluOS multi-room streaming glazbe i Dirac Live room korekcija.
