Focusrite Scarlett 18i20 4th Gen 26-in/26-out Audio Interface

The Focusrite Scarlett 18i20 4th Gen is the largest interface in the current Scarlett range, a 1U rack-mountable USB interface with 26 simultaneous inputs and 26 outputs. It provides eight ultra-low-noise microphone preamps with sixty-nine decibels of gain range and an A-weighted equivalent input noise of minus one hundred and twenty-seven dBu. Two front-panel inputs accept microphones, line sources or instruments. Each preamp can be controlled remotely, and Auto Gain and Clip Safe help set levels and prevent clipping across all eight channels. Two Air modes, Presence and Presence with Harmonic Drive, add console-style character to vocals and guitars. Focusrite specifies a 122-decibel A-weighted dynamic range on the balanced line outputs and recording at up to 24-bit and 192 kilohertz. There are ten line outputs including alternative speaker switching, two headphone outputs and a built-in talkback microphone. Two ADAT inputs and outputs add up to sixteen channels at 44.1 or 48 kilohertz, alongside S/PDIF, MIDI and word clock connections. The unit uses an external power supply rather than USB bus power, measures 442 by 46.55 by 259.73mm and weighs 3.304kg. Focusrite's software bundle, including the Hitmaker Expansion, is included.
