TASCAM US-20x20 interfaccia audio USB 20 ingressi, 20 uscite (totali). Contenitore in alluminio e connettori di ingresso COMBO E JACK per microfoni e linea. Non necessita di Driver per funzionare su computer (compatibile ASIO e Core Audio).10 uscite audio analogiche e 2 uscite cuffia separate.
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.
