Overview

The Focusrite Scarlett 4i4 4th Generation is a versatile four-input, four-output USB-C audio interface that bridges the gap between simple two-channel units and larger rack-mounted interfaces, making it an excellent choice for musicians who need more routing flexibility. It features two upgraded Scarlett preamps with Air mode and 69 dB of gain on the front-panel XLR/TRS combo inputs, plus two additional line-level inputs on the rear panel for connecting synthesizers, drum machines, or other line-level sources. MIDI In and Out connections on the rear panel allow direct connection of MIDI controllers and hardware synthesizers without a separate MIDI interface. The four balanced outputs enable a dedicated headphone mix alongside a separate monitor mix, or the routing of audio to external effects processors and hardware. The 24-bit/192 kHz converters provide professional-grade audio quality, and the preamp performance matches the rest of the 4th Gen Scarlett range. Auto Gain and direct monitoring features simplify the recording process, while Focusrite Control software provides detailed routing and mix control. The bus-powered design keeps the setup clean, and the rugged aluminum enclosure is built for years of daily use. This interface is ideal for electronic musicians, small home studios, and producers who need MIDI connectivity and more than two inputs. The two preamps may still feel limiting for users who need to record a full band or multiple microphones simultaneously.

4.7 /5
The 4th Generation Scarlett 4i4 marks a significant evolutionary leap for Focusrite's mid-tier workhorse. While the iconic red aluminum chassis remains, the internal architecture has been overhauled with converters borrowed from the flagship RedNet series, offering a noticeable bump in clarity and a massive 120dB dynamic range. The standout features for intermediate producers are the 'Auto Gain' and 'Clip Safe' functions. For a solo musician tracking vocals or guitar, these tools take the guesswork out of gain staging, effectively acting as an invisible assistant engineer. The updated 'Air' mode now includes a 'Harmonic Drive' setting, which adds a pleasing analog-style saturation that helps tracks sit better in a mix without reaching for plugins immediately. Ergonomics are top-notch; the halo indicators are more precise than previous iterations. However, users should note that the two rear inputs are fixed line-level, meaning you'll still need external preamps if you intend to mic up a full drum kit. While the price has crept up, the inclusion of MIDI I/O and the vastly improved preamp gain (69dB) makes it a powerhouse for synth enthusiasts and podcasters alike. It's a polished, reliable interface that feels less like a starter kit and more like a professional tool.
