Eight of our most detailed, ultra-low-noise preamps.
Connect your studio to 18i20’s 4th-Generation remote-controlled preamps — Scarlett’s most transparent and detailed ever. 69dB of gain range provides all of the headroom you'll need to get the best result from the most intense multi-track recordings. Control preamp levels from anywhere in the studio using the Focusrite Control 2 apps, giving you the freedom to adjust settings remotely.
Auto Gain and Clip Safe.
Let 18i20 handle your levels. Auto Gain will set all eight microphone preamp levels instantly and Clip Safe keeps them in the sweet spot, automatically tweaking the gain if you’re in danger of clipping. You'll never lose a take again.
Mix your way, with independent outputs.
Take full control of your routing and mixing preferences using the Focusrite Control 2 apps, anywhere in the studio.
Dial in the perfect headphone mix for the artist, or route the signal directly to outboard gear to put the finishing touches on your mix.
Get that big console sound with two re-engineered Air modes.
Presence mode boosts your signal’s high-end, bringing the sound to the front of the mix. Create intimate vocal recordings, capture every detail of acoustic guitars, and hear your drum overheads shimmer.
Presence and Harmonic Drive mode boosts mid-range harmonics in your sound, making its unique character shine through the mix. Try it on guitars, vocals, or anything else that needs a little more punch.
Huge 122dB dynamic range for incredible recordings.
Scarlett delivers incredible audio quality, with converters direct from our flagship RedNet interfaces — as found in high-end studios around the world.
Powerful sound, powerful control.
Two custom-designed headphone amps deliver clear, powerful sound for high-impedance headphones, offering the best playback ever from a Scarlett.
A built-in talkback mic ensures seamless communication to the artists, while alt monitor switching lets you A/B your mixes between two speaker pairs.
All the software you need to make a hit record.
Once you've got started with Ableton Live Lite, Pro Tools Intro+, or six months of FL Studio Producer Edition recording software (all included), the Hitmaker Expansion bundle has everything you need to bring big studio sound to your songs, with an unbeatable range of record-making studio tools from the biggest names in the business.
