## Long description

The Focusrite Scarlett 18i20 (4th Gen) is a rackmount studio audio interface offering extensive I/O for multitrack recording, monitoring and hybrid hardware/software setups. Equipped with eight remote-controlled ultra-low-noise microphone preamps, two additional front-panel preamps with instrument inputs, ADAT and S/PDIF optical I/O, MIDI and Word Clock, the Scarlett 18i20 supports up to 24-bit/192 kHz conversion and USB-C connectivity for low-latency recording. This interface provides flexible routing with multiple line outputs, independent headphone feeds and on-board features such as Auto Gain, Clip Safe and two selectable Air modes to shape high-frequency presence and harmonic character.
Advantages
The 18i20 combines high channel count with refined preamp design, delivering a wide dynamic range and clear, low-noise recordings suitable for professional and project studios. Remote control of preamp levels via Focusrite Control 2 and mobile apps simplifies complex sessions and monitoring setups. Auto Gain and Clip Safe automate level-setting to reduce the risk of distorted takes, while dual Air modes reproduce classic console-style presence and harmonic enhancement. Expandability through ADAT and S/PDIF allows integration of additional preamps and converters without replacing core hardware.
Suitable for
 Multitrack recording of bands, drum kits and live sessions
 Home and project studios needing extensive analogue I/O
 Hybrid setups using outboard synths, effects and hardware instruments
 Mixing and monitoring with multiple speaker pairs and headphone feeds
 Integration with MIDI gear and external digital converters

How to use
Connect the Scarlett 18i20 to your computer via USB-C and install the Focusrite drivers and Focusrite Control 2 app for Windows or macOS. Patch microphones, instruments and line-level sources to the rear and front inputs as required, and configure ADAT or S/PDIF connections to add external preamps or converters. Use Focusrite Control 2 or the mobile companion app to set preamp gain, routing, headphone mixes and monitor outputs. Enable Auto Gain to set preamp levels automatically and activate Clip Safe to prevent clipping during recording. Toggle Air modes on individual preamps to add presence or harmonic drive where needed.
Usage recommendations
For best results, calibrate input gain using Auto Gain then fine-tune manually to ensure peaks remain below clipping while preserving dynamic range. Use ADAT expansion for additional mic channels at 44.1/48 kHz or fewer channels at higher sample rates. Route separate monitor mixes through the independent outputs to provide performers with tailored headphone or speaker feeds, and employ Word Clock when syncing multiple digital devices to maintain sample-accurate timing.
