Mirage 4 Evo

Mirage è un nome importante nella storia dei processori broadcast AEV, e le migliaia di unità operanti in tutto il mondo testimoniano il successo di questo apparato, per questo motivo ci è sembrato giusto perdurare questo nome anche con l’Evoluzione Digitale.

Mirage 4 Evo è un processore audio completamente digitale, basato su tecnologia DSP, che fornisce tutte le funzioni necessarie all’emittente Radio, il tutto ad un costo competitivo e con un ottimo rapporto qualità/prezzo, forte dell’avanzato livello della configurazione standard.
