Scarlett 18i20
Focusrite’s Scarlett 18i20 is the latest in the company’s new generation of multi-channel USB-based audio interfaces, featuring eight award-winning Focusrite microphone preamplifiers, designed specifically for the computer interface environment, delivering legendary Focusrite sound quality.
Focusrite’s mic preamps are found in the world’s top studios and give the 18i20 an unequalled level of performance, with low noise, minimal distortion and enormous dynamic range. The Scarlett preamps offer exceptional headroom, and two front-panel inputs also offer 10dB pad buttons to handle the highest-level inputs without distortion.
