Tascam US-1x2 USB 2.0 Audio interface
US-1x2 er en 1-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-1x2 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-2x2 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-2x2 benyttes sammen med iOS-enheder).

1 We strongly recommend using a Tascam PS-P520E or the USB power adapter included with the iPad/iPhone. No USB power adapter is included with an iPod Touch. To use it with an iPod Touch, purchase a genuine Apple USB power adapter (that can supply 5 V and a current of at least 700 mA) separately.
2 We strongly recommend using a Tascam BP-6AA external battery pack. If using another external battery pack or mobile battery, purchase one that can supply 5 V and a current of at least 700 mA.
