Gearank High Notes

The Scarlett 18i20 2nd Gen appeared on our recommended list for USB Audio Interfaces from November 2016 until December 2019.


Note: This 2nd Gen version has been superseded by the Focusrite Scarlett 18i20 3rd Gen.

Part of Focusrite's second generation of audio interfaces, the Scarlett 18i20 carries over the best of the original version with upgraded 24-bit/192kHz resolution, improved drivers and software bundle.

It gives you the 8 combo XLR/TRS inputs with Focusrite's popular mic preamps, a 2-channel S/PDIF input and an optical ADAT input for expansion to a total of 18 channels.

This second generation version also benefited from the collaboration between Pro Tools developer AVID and Focusrite, resulting in improved software control and the inclusion of the Pro Tools | First Focusrite Creative Pack into the software bundle included with each unit.
