Product Information

The Focusrite Scarlett 18i20 is a professional-grade USB audio interface built for complex studio environments. With 18 inputs and 20 outputs, including eight high-gain mic preamps, ADAT, SPDIF, and MIDI I/O, it offers extensive connectivity for multi-instrument recording and hardware integration. The preamps provide 69dB of gain, featuring Auto Gain and Clip Safe to ensure optimal levels without distortion. The Air mode enhances recordings with a vintage console-like character, adding depth and clarity to vocals and instruments.

Designed for seamless recording and monitoring, the Scarlett 18i20 includes high-performance 24-bit/192kHz AD/DA conversion with a wide 120dB dynamic range. Its built-in monitoring tools feature dual independent headphone amps, A/B speaker switching for precise referencing, and a talkback microphone for studio communication. Eight channels of LED bar metering allow for real-time level monitoring, ensuring precise control over your sessions.

With Focusrite Control 2 software, setting up routing, mixing, and monitoring is intuitive across both desktop and mobile devices. The software enables remote preamp gain adjustments and custom monitor mixes, giving you control from anywhere in the studio. Additionally, the Scarlett 18i20 supports up to 16 additional inputs and outputs via ADAT, making it ideal for expanding your setup. Included software such as Pro Tools Artist, Ableton Live Lite, and premium plugins ensure a complete production-ready toolkit.
