MARK LEVINSON No.383
Integrirano pojačalo
 
No.383 isporučuje 100 W snage pri opterečenju od 8 ohma, odnosno 200 W na 4 ohma. Dvostruka mono konfiguracija sa dva toroidalna transformatora osigurava potpunu odijeljenu elektroniku lijevoga i desnoga kanala, a tri nezavisna napajačka stupnja pružaju stabilno napajanje svim krugovima. Predpojačivačka sekcija nudi mogućnost podešavanja razine ulaznog signala (gain) različitih izvora što olakšava uparivanje sa zvučnicima različitih osjetljivosti. Izlazni solid-state stupanj koristi iste elemente kao i referentni mono-blokovi No.33H. Kompletno pojačalo je izgrađeno bez kompromisa bilo koje vrste, pa je i zbog toga No.383 jedini integrirac u ponudi Mark Levinson.
