Focusrite Scarlett 18i20 18x20 USB2 Audio-Interface
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.
Focusrite interfaces are perfect partners for Pro Tools, so Scarlett 18i20 comes with Pro Tools First Focusrite Creative Pack, as well as Ableton Live Lite recording software and a suite of software and samples, so you can start recording straight away. Scarlett 18i20 works flawlessly with all major DAWs on Mac and PC, and we continue to work with Avid to ensure it is compatible with every update to Pro Tools.
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 Scarlett OctoPre 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.
World Famous Preamps
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.
Create Separate Monitor Mixes
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.
Revolutionise Your Workflow
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.
New Generation - Better In Every Way
The latest generation Scarlett 18i20 is packed full of upgrades. It operates at sample rates all the way up to 192kHz with new super-low latency* that lets you record and monitor with software effects in real time.
We also completely redesigned the instrument inputs so they can handle even the hottest guitar pick-ups, and built in new analogue protection circuitry across the inputs and the outputs, to guard your interface against unwanted power surges.
