Interfaccia Audio – Mixer Digitale USB 3.0/2.0

DESCRIZIONE

Continua la nostra tradizione e passione per l’audio con l’US-20x20 "Celesonic" , il fiore all’occhiello delle interfacce Tascam. Progettata per l’uso in studi di registrazione professionali e home studios, questa interfaccia puo’ registrare audio fino a 192 kHz/24bit e utilizza USB 3.0 come standard di trasmissione dati. Inoltre con la modalità Mic Preamp e modalità Mixer, diventa uno strumento molto versatile oltre ad essere un’interfaccia multi-canale.

I preamplificatori microfonici sono essenziali per ottenere la massima qualità audio. Gli otto preamp Tascam Ultra-HDDA hanno un rumore di ingresso equivalente (EIN) di -125 dBu e 20 dB di headroom sugli ingressi microfonici e di linea che permettono di gestire facilmente forti pressioni sonore generate da percussioni e strumenti a fiato.

Utilizzando un processore Blackfin ad alte prestazioni, l’US-20x20 offre un avanzato mixer DSP con controlli EQ, compressore e riverbero per ogni canale. Il processore eccelle non solo sulle dinamiche e gli effetti, ma consente la trasmissione multicanale tramite USB 3.0.

La possibilita’ di cambiare modalita’ di utilizzo consente alla US-20x20 di funzionare come preamplificatore microfonico indipendente, come interfaccia audio, oppure come un mixer per applicazioni live.

La completa connettività ai vari tipi di apparecchiature audio si ottiene utilizzando gli ingressi analogici e le uscite, ingresso e uscita digitale tramite connettori coassiali e ottici, MIDI e Word Clock mediante connettori BNC.

Lo stile accattivante e razionale della US-20x20, ne rendono particolarmente semplice l’inserimento nella propria postazione di registrazione. Nella confezione è incluso un adattatore per montaggio a rack.

I nostri originali preamplificatori microfonici Ultra-HDDA consentono di acquisire audio di alta qualita’ da qualsiasi fonte semplicemente ruotando una manopola. Questi sono gli stessi preamplificatori microfonici che equipaggiano i nostri registratori professionali HS-P82, molto popolari nel settore broadcast e cinema. Questi versatili preamp oltre ad avere ingressi di linea per tastiere ed altre apparecchiature, sono in grado di gestire sia microfoni a condensatore che dinamici, e vi permetteranno di ottenere registrazioni di alta qualità, anche senza essere un vero esperto.
