Handle Anything That Comes Your Way Our latest generation 18-in, 20-out USB audio interface can handle just about anything your band or studio can throw at it. Beautiful and rack mountable, it gives you loads of I/O, pristine sound quality, separate stereo headphone mixes, extensive expansion options and round-trip latency as low as 2.74ms*, all in a 1U space. Inputs Your Studio Deserves Scarlett 18i20 puts eight natural-sounding combination inputs at your disposal. We put two on the front, where you need them most, with newly designed instrument inputs that can handle even the hottest signals. We put six more on the back, so you can leave your mics, synths, keyboards, mixers and effects processors permanently plugged in and ready to go. If that isn’t enough for you, connect an eight-channel mic pre like the Focusrite OctoPre Mk II to the ADAT input for a total of 16 analogue inputs. Add the two channels of digital audio via S/PDIF and 16 channels of MIDI, and you can record just about anything you want.
