The Focusrite Scarlett 18i20 4Gen is a professional USB audio interface designed for producers, engineers, musicians, and modern recording studios that require extensive connectivity and exceptional sound quality. The fourth generation Scarlett 18i20 delivers 26 inputs and 26 outputs, eight ultra-low-noise microphone preamps, premium converters with up to 122dB dynamic range, and advanced recording tools that make professional production easier than ever.

Whether you're recording a full drum kit, tracking a live band, connecting hardware synthesizers, or mixing complex sessions, Scarlett 18i20 4Gen provides all the I/O and routing flexibility needed for demanding studio environments.

Key Features

The interface includes eight high-performance Scarlett microphone preamps with an impressive 69dB gain range and extremely low noise floor, making it ideal for capturing vocals, acoustic instruments, drums, and dynamic performances with outstanding clarity.

Two front-panel Hi-Z instrument inputs allow direct connection of electric guitars and basses with authentic amp-like response, while ten line outputs make it easy to integrate studio monitors and external outboard gear.

Scarlett 18i20 4Gen also introduces two enhanced Air modes inspired by classic studio consoles. Presence mode boosts the high frequencies and brings recordings forward in the mix, while Presence & Harmonic Drive adds rich harmonic character and analog-style warmth.

Advanced Recording Hub for Professional Studios

With extensive connectivity options, the Scarlett 18i20 4Gen acts as the central hub of any professional studio setup. The interface can be expanded with up to 16 additional channels via ADAT and two more channels through S/PDIF, allowing seamless integration with additional preamps and digital hardware.

The 24-bit/192kHz converters provide detailed, transparent recordings with exceptional accuracy. Focusrite uses converter technology derived from its flagship RedNet range, trusted by professional studios around the world.

Built-in Auto Gain and Clip Safe technology simplify recording workflows and help prevent clipping during sessions. Auto Gain instantly sets optimal microphone levels, while Clip Safe continuously monitors incoming signals and automatically adjusts gain when needed.

With eight microphone preamps and extensive expansion options, it easily handles drum recordings, full bands, vocal sessions, and hardware synthesizer rigs.

Electronic music producers will appreciate the flexible routing capabilities, MIDI integration, and high-quality monitoring options. The interface is also an excellent solution for content creators and streamers who need reliable audio performance and professional-grade sound quality.
