18 In/20 Out Rackmount USB Audio Interface with 8 Mic Preamps, SPDIF and ADAT
Make your space a studio.
Scarlett interfaces sit at the heart of more music-making, recording and production spaces than any other range, and 18i20 is Scarlett’s most versatile interface. The rack-mountable 3rd Generation 18i20 gives you 18 inputs and 20 outputs of incredible sound quality. Enough to make any space into a fully-fledged recording studio.
- Eight of the best performing Scarlett mic preamps the range has ever heard – now with Air – for miking up guitars or recording vocals
- Two high headroom instrument inputs, for plugging your guitar or bass straight in
- Four monitor outs, featuring anti-thump tech and speaker switching
- Built-in talkback mic, for talking to the band from your studio
Channel your inner producer
18i20’s high channel count and even higher audio quality are designed to give you all the ins and outs you need to get the best sound every time. Leave all your instruments plugged in for easy writing and recording or put the vast I/O to work in large recording sessions. Make anywhere your control room with the built-in talkback mic. Reference your recordings on multiple monitor setups with speaker switching. Wherever you take 18i20, you’re ready to produce.
Your recordings are 30 years in the making
We’ve been making mic preamps for 30 years, and the 3rd Gen mic pres are the best Scarlett has ever heard. The 24-bit/192kHz converters give your recordings clarity and detail. Air mode breathes life into vocals, adding unique high-end detail. Our decades of experience mean Scarlett sounds just like you.
Drum up some incredible recordings
With Scarlett 18i20’s dual ADAT optical In and Out ports, you can expand your recording and mixing capabilities, adding up to eight further inputs and outputs at 48kHz or 96kHz via a mic pre such as Scarlett OctoPre or Scarlett OctoPre Dynamic, or four channels at 192kHz. That’s more than enough channels to mic up the whole band and route a full mix to a console or summing box.
