The Focusrite Scarlett 2i2 is a portable USB-powered two input/output audio interface from UK-based Focusrite. It’s the perfect unit for a small home studio setup, especially for singer-songwriters who don’t need more than two preamplifier channels at a time. It’s rugged enough to take with you on the road, and the included headphone output means you can work on music any time of the day without disturbing anyone.
On the front of the unit, there are two XLR/TRS/TS combo jacks for microphones, guitars, and other instruments. Both preamp channels have switchable 48V phantom power. In addition to the monitor volume knob, there is also a headphone output with its own volume control knob. On the back of the unit, there are two TRS balanced outputs for your monitor speakers and a powered USB port to connect to your computer. Notice there isn’t a connection for a power adapter anywhere. The Focusrite Scarlett 2i2 is USB bus-powered, so you don’t have to worry about a power cable.
