The AudioBox44vsl from Presonus is a two-channel USB computer audio interface. Designed to be portable, the unit utilizes 24-bit converters that sample at 44.1, 48, 88.1, or 96 kHz. Two high-quality PreSonus microphone preamps with switchable 48V phantom power are also provided, as are combination jacks for 1/4" or XLR inputs, MIDI I/O, and solid drivers. Whilst recording, you can achieve zero-latency monitoring with a knob that allows you to blend signal from the preamp with signal in your DAW, giving you a tailored balance of both sources.
The interface is bundled with the Studio One Artist 3 DAW software for Mac and Windows, and includes the Studio Magic plug-in suite, providing effects, virtual instruments, and third-party loops, software, and instrument sounds. This unit is sturdy enough to be taken on the road, though also finds its home in the studio.
