Housed in a 1U rack-mountable enclosure, the third-generation 18i20 boasts extensive simultaneous I/O comprising eight mic preamps, 18 inputs and 20 outputs in total. Take your studio to the next level with the 18i20, offering superior sound quality, talkback functionality and onboard speaker switching. Improved A-D and D-A conversion ensures your recordings and playback will sound clear and pronounced up to 24-bit/192kHz, vital to helping you perfect your mix.

The Scarlett 18i20 features eight of Focusrite's best-ever-performing third-generation Scarlett mic preamps: with optional Air setting to reproduce the Air effect of their original ISA mic preamp, giving your vocal or acoustic recordings a brighter and more open sound. There's also a pad on every mic preamp to accommodate higher-level signals without clipping. The two front panel high-headroom instrument inputs allow you to record guitars and basses without any clipping or unwanted distortion.

Speaker-switching technology allows you to switch between main and alt monitors to get a new perspective on your mix, and the new built-in talkback mic lets you communicate with your recording artist at the touch of a button, helping you capture that perfect take.

A pair of virtual loopback inputs allows you to capture a stereo feed of any combination of hardware input and software playback channels – making podcasting, live streaming and sampling tasks easier.

Scarlett 18i20 is designed to stand up to days on the road and connects straight to your Mac® or PC via USB cable. There's no better way to step into studio recording – your Scarlett interface comes with some of the best loved tools in the business, including Ableton Live Lite, Avid Pro Tools Artist and Hitmaker Expansion, with exclusive content from legendary Auto-Tune® creators Antares®, along with Brainworx®, Softube®, Landr, XLN Audio®, Relab and more.

If that wasn't enough, Focusrite have partnered with Splice to give 3rd Gen. interface owners a free 3-month Splice Sounds subscription when setting a new Splice account.
