Take your studio to the next level with the 18i20, offering superior sound quality, talkback functionality and onboard speaker switching. Improved A-D and D-A conversion ensures your recordings and playback will sound clear and pronounced up to 24-bit/192kHz, vital to helping you perfect your mix.The Scarlett 18i20 features eight of Focusrite’s third-generation Scarlett mic preamps: with optional Air setting to reproduce the Air effect of their original ISA mic preamp, giving your vocal or acoustic recordings a brighter and more open sound.
