Focusrite Scarlett 18i16 4th Generation USB-C Audio Interface
The Focusrite Scarlett 18i16 4th Generation is a powerful 18-in/16-out USB-C audio interface designed to be the central hub of your home or professional studio. Featuring four ultra-low-noise Scarlett mic preamps with up to 69dB of gain, multiple line and instrument inputs, MIDI I/O, and extensive digital expandability via ADAT and S/PDIF, the 18i16 is ideal for producers managing multiple sources. It supports simultaneous multitrack recording and monitoring with crystal-clear 24-bit/192kHz resolution and a dynamic range up to 122dB—making it a studio essential.
Tailored for flexibility, the 18i16 includes powerful features like Auto Gain, Clip Safe, and dual Air modes (Presence and Harmonic Drive) to replicate big-console tones. Mix independently for headphones, monitors, and line outs—all remotely controlled through the Focusrite Control 2 desktop and mobile apps. Whether bus-powered via USB-C or with an external power supply, this interface adapts seamlessly to mobile or fixed setups. Bundled with the Hitmaker Expansion software suite and a 3-year warranty, the Scarlett 18i16 gives you all the tools to produce, mix, and release pro-quality tracks.
