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. All eight analogue inputs feature pristine and natural sounding Scarlett preamps, backed by 30 years of design experience and found in the world’s top studios. These guarantee exceptional headroom, plenty of clean gain, low noise, minimal distortion and a dynamic range that is unrivalled in this class. As well as eight balanced analogue line outputs, Scarlett 18i20 gives you two independent stereo headphone outputs so you can give engineer and artist their own separate, fully-customised mixes. An unrivalled round-trip latency as low as 2.74ms* completely revolutionises your workflow. You can work entirely inside your DAW for both overdubbing and playback, and use your plugins while recording - depending on your software, settings and computer, of ourse. You’ll also get the best out of vocal performances, by applying real-time comfort reverb to artists' headphones. Focusrite redesigned Scarlett 18i20's instrument inputs and given them plenty of extra headroom, so you can handle extreme levels without any unwanted clipping or distortion. If you’re recording extra loud instruments, you can also engage the 10dB pad in Focusrite Control software.
