Focusrite Scarlett 18i20 USB Audio Interface - 3rd Gen

18-in/20-out USB audio interface featuring eight world-class preamps, cutting-edge converters, and four monitor outputs with built-in talkback functionality

Product Description

With 18 inputs and 20 outputs packed into a compact 1U rack-mountable chassis, the Focusrite Scarlett 18i20 3rd Gen is the most ambitious USB interface Focusrite has ever created. Take your recordings to the next level with eight world-class preamps, cutting-edge converters, and four monitor outputs with built-in talkback functionality.


Featuring 10 analog inputs, the Scarlett 18i20 is big enough for even the most demanding recording sessions. Equipped with eight class-leading preamps, eight balanced line inputs, and two high-headroom instrument inputs, the Scarlett 18i20 has everything you need to record a full band—including drums, bass, guitars, synthesizers, vocals and more. All eight preamps are equipped with pads and a switchable Air setting, based on the original Focusrite ISA preamp. Daisy-chain a second interface using the ADAT connection for up to eight additional inputs.


Capture crystal-clear recordings and mixes using the Scarlett 18i20’s groundbreaking AD-DA converters, capable of delivering pristine sound at sample rates up to 24-bit/192 kHz. Reference your mixes on multiple sets of monitors using four dedicated monitor outputs with anti-thump speaker switching technology. Six additional line-level outputs make adding analog signal processing a breeze. Expand your I/O even further with up to eight additional input channels via ADAT.

Create custom mixes for multiple performers using two independently controlled headphone outputs. Quickly monitor any combination of hardware input and software playback channels using a pair of virtual loopback inputs.


The Scarlett 18i20 is bundled with a massive collection of creative software to help you tackle any project that comes your way.

Start recording quickly with two popular digital audio workstations (DAWs): Ableton Live Lite or Pro Tools First Focusrite Creative Pack. Both are packed with powerful editing tools and for tine-tuning your performance.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
