US-20x20
Tato profesionální zvuková karta je určena pro vážné zájemce o nahrávání a nahrávací studia. Nabízí nahrávání v kvalitě 24 bitů / 192 kHz, WORD CLOCK, intuitivní ovládání a 8 špičkových mikrofonních předzesilovačů Ultra-HDDA s gainem až 56 dB. Dále jsou zde další 2 symetrické linkové vstupy, 8 optických digitálních vstupů a výstupů S/MUX, 2 koaxiální digitální vstupy a výstupy S/PDIF.
US-20x20 lze použít jak s PC, tak i s iPadem a jinými iOS zařízeními. Stačí klasická kamerová redukce a přiložený síťový adaptér.
Díky pokročilému Blackfin DSP softwaru můžete nasadit čtyřpásmový parametrický ekvalizér a kompresor na každý kanál, reverb a bezlatenční monitoring umožní pohodlný poslech při nahrávání.
US-20x20 má 3 funkční módy: zvuková karta, mikrofonní předzesilovač nebo mixážní pult.
