The Focusrite Scarlett 18i6 is an 18 in / 6 out USB 2.0 audio interface designed to make home multitrack recording a breeze. Alongside two award-winning Focusrite preamps, six high-quality analogue inputs allow you to simultaneously record guitar, bass, vocals and keys. You don???t need to stop there either ??? pop in the ADAT optical cable from an outboard eight-channel mic pre unit such as the Focusrite OctoPre MkII and you can track the drums at the same time.
