KRELL EVO 402
izlazno pojačalo
Opis proizvoda:
Novo Krellovo pojačalo u svakom je pogledu ostalo vjerno tradiciji
izrade i kvalitete – od prednje ploče do zvučničkih terminala, sklopova
najviše klase i besprijekornog finiša.
Active Cascade toplogija u potpunosti eliminira negativnu povratnu vezu,
a oko zasebnih blokova pojačanja javlja se samo lokalna povratna veza.
Rezultat je izvanredno otvoren i fluidan zvuk. EVO 402 ima napajanje od
5000 VA, s tim da električna i magnetska zaštita sprečavaju da
interferencije dopru do kritičnih sklopova pojačala.
Napredni sustav za praćenje kontrolnih parametara stalno mjeri
polarizaciju, impedanciju opterećenja, izlazni napon i radnu
temperaturu.

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.
