The US-122 is a USB powered audio/MIDI interface designed for Digital Audio Workstation (DAW) software applications. Its design incorporates a two-input, two-output 24-bit audio interface with balanced inputs, input inserts, guitar impedance matching, phantom powering, and a 16-channel MIDI inter-face. Because the US-122 is USB-based, it’s the ideal companion to any desktop or laptop-based digital recording setup. And since it’s as compact, like a laptop, requiring no additional power source, it can be combined with one to create a complete portable digital audio workstation solution
