Housed in a 1U rack-mountable enclosure, the 3rd Gen 18i20 boasts extensive simultaneous I/O comprising eight mic preamps, 18 inputs and 20 outputs in total. 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. The Scarlett 18i20 features eight of Focusrite's best-ever-performing 3rd Gen 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. There?s also a pad on every mic preamp to accommodate higher-level signals without clipping. The two front panel high-headroom instrument inputs allow you to record guitars and basses without any clipping or unwanted distortion. Speaker-switching technology allows you to switch between main and alt monitors to get a new perspective on your mix, and the new built-in talkback mic lets you communicate with your recording artist at the touch of a button. A pair of virtual loopback inputs allows you to capture a stereo feed of any combination of hardware input and software playback channels - making podcasting, live streaming and sampling tasks easier.
