USB 2.0 audio interface with eight Focusrite mic preamps.

With its versatile complement of no less than 20 outputs and 18 inputs – including eight of Focusrite’s award-winning Focusrite microphone preamplifiers designed specifically for the computer interface environment and delivering legendary Focusrite sound quality – the rack-mounting 18i20 quite literally forms the heart of the modern digital studio, combining the central features of Focusrite’s USB 2.0 audio interface range: mic preamps that build on 30 years of experience and precision 24/96 analogue/digital conversion for the very best quality into and out of your DAW.

Focusrite mic preamps, backed by 30 years of design experience and found in the world’s top studios, give the 18i20 an unequalled level of performance, with low noise, minimal distortion and enormous dynamic range. Dual front-panel inputs also offer 10dB pad buttons to handle the highest-level inputs. 18i20 supports both Macintosh and Windows computers as well as the iPad (Camera Connection Kit required).

With its 18 inputs and 20 outputs, Scarlett 18i20 has the I/O capability to take on the vast majority of day-to-day studio tasks with maximum quality and maximum flexibility. Scarlett 18i20 features six combo XLR/jack mic/line inputs plus two front-panel XLR/jack mic/line/instrument inputs with 10dB pad buttons, 10 analogue line outputs two providing independent headphone outputs on the front panel, and ADAT and S/PDIF digital I/O. Use the additional ADAT interface to bring in digital sources or to add preamps such as Focusrite’s OctoPre Mk II, bringing the mic pre complement to 16 channels – ideal for recording a complete band. 18i20 also provides MIDI I/O and Word Clock out for digital synchronisation when required.

Scarlett 18i20’s prodigious I/O capability is backed by Focusrite’s class-leading precision digital conversion technology, operating at up to 96 kHz, 24-bit and designed to ensure that you get the very highest quality into and out of your audio software – all major digital audio workstations are supported, and with the latest Red 2 and Red 3 AAX plugins (included), 18i20 is the perfect partner for Pro Tools.

Suitable for Windows, Macintosh and even iOS platforms, Scarlett 18i20’s USB 2.0 connection suits almost any computer and delivers a powerful combination of precision digital conversion and award-winning mic pres with 30 years of experience behind them. For the best performance, don’t connect your interface to the same bus as your drives – use a USB interface when you don’t have USB drives.
