Tascam US-4x4HR USB 2.0 Audio interface
US-4x4 er en 4-input/4-output USB lyd/MIDI-interface perfekt til nybegyndere. Den tilbyder seriøse optagelsesegenskaber med 96 kHz/24-bit kvalitet med brugervenligheden i højsædet. Mic preamps er nøglen til sublim lydkvalitet og US-4x4 tilbyder Ultra-HDDA mic-preamps med 125 dBu EIN rating som betyder den har et meget lavt støjniveau. Pågrund af den brede dynamiske vidde kan interfacen både bruges sammen med dynamiske og kondensatormikrofoner. Dette gør enheden optimal til optagelse af vokal, piano og akustiske guitarer. US-4x4 kan benyttes sammen med DAW-applikationer, den kan også benyttes som en lyd-interface med iPads og andre populære iOS-enheder, ved brug af en Apple Lightning-to-USB kamera-adapter (en ekstra AC-adapter er nødvendig når US-4x4 benyttes sammen med iOS-enheder).
