The Focusrite Scarlett 18i20 4th Generation is a rack-mountable 18-input, 20-output USB-C audio interface designed for professional home studios, project studios, and small commercial facilities that need to record a full band or multiple sources simultaneously. It features eight upgraded Scarlett preamps with individually switchable Air mode and up to 69 dB of gain, allowing all eight XLR/TRS combo inputs to handle everything from quiet ribbon microphones to hot line-level synths. The converters deliver pristine 24-bit/192 kHz resolution with improved dynamic range, and the preamp performance is the best in Scarlett history with low noise and transparent capture across all channels. ADAT optical inputs expand the channel count to 18 simultaneous inputs when paired with an external preamp, while dual MIDI I/O connections and S/PDIF provide comprehensive digital connectivity. The front panel includes two additional instrument/line inputs for quick access, dual headphone outputs with independent volume controls, and a large monitor knob with dim and mute functions. Focusrite Control software provides comprehensive routing, monitor mixing, and loopback functionality. The 1U rack-mountable metal enclosure is built for permanent studio installation with reliable connectivity. This interface is ideal for bands, drum recording, and multi-source studio sessions where eight quality preamps and flexible routing are essential. The USB-C bus power is not available at this tier, requiring an external power supply that limits portability.
