Focusrite Scarlett 18i20 18×20 USB Audio Interface (3rd Generation)
Description
The heart of your setup. High channel count. Professional quality audio. Pro features, including talkback mic and speaker switching. 18i20 makes any space a studio.
The eight 3rd Generation Scarlett mic preamps sound great, with enough IO to record a full band 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. Ten 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. Built-in talkback mic makes it easy to talk to your band during busy recording sessions. Loopback makes streaming and sampling simple.
