Four of our most detailed, ultra-low-noise preamps.
Plug into 18i16’s remote-controlled preamps — Scarlett’s clearest and most detailed ever, with a huge 69dB gain range to get the best from every microphone.
Auto Gain and Clip Safe.
Let 18i16 handle your levels. Auto Gain sets your levels 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
With 18i16, headphones, monitors, and line outs each get their own mix, so you can create the perfect studio setup for your speakers, the artist's headphones, or outboard gear — controllable anywhere in the studio via the Focusrite Control 2 apps.
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.
