High channel count. Small footprint. Whatever you’re recording, wherever you are, take your whole studio with you. 18i8 is studio sound for the whole band.
The four 3rd Generation Scarlett mic preamps sound great straight out of the box. Air mode recreates the legendary effect of Focusrite’s ISA mic pres and makes vocals and guitars shine. The high-impedance, high-headroom instrument inputs are great for recording guitar or bass without clipping, while our iconic Gain Halos make it easy to set input levels fast. Four balanced outputs with Anti Thump speaker switching are hum-free for pristine monitoring and are ideal as FX sends. Two powerful headphone outputs with individual level controls let you monitor, mix and master however you want. Loopback makes streaming and sampling simple. And it comes with some of the best-loved tools in the business, including Ableton Live Lite, Avid Pro Tools Artist and Hitmaker Expansion – with plugins from legendary Auto-Tune® creators Antares®, Brainworx®, Softube®, Landr, XLN Audio®, Relab and more.
