Focusrite Scarlett 18i8 USB Audio Interface - 3rd Gen

Ultra-flexible 18-in/20-out USB audio interface with four console-grade preamps, eight balanced line-level inputs, and four dedicated monitor outputs

Product Description

The Focusrite Scarlett 18i8 3rd Gen is an 18-input, 8-output USB audio interface that offers the flexibility to adapt to any recording environment. With four console-grade preamps, eight balanced line-level inputs, and four dedicated monitor outputs, no session is too big for the Scarlett 18i8.


The Scarlett 18i8 offers eight analog inputs, with four world-class preamps for pristine sound. Breathe new life into your vocal and acoustic instrument recordings with the switchable Air setting, based on the original Focusrite ISA preamp. All four preamps also feature a dedicated pad—perfect for recording hard-hitting drummers, loud guitar amps and more.

You can also track guitars and basses directly using two high-headroom instrument inputs. Record synthesizers, drum machines and more using four additional fixed-line inputs on the rear. Expand your I/O with up to eight additional channels via the built-in optical input.


The new Scarlett 18i8 is equipped with state-of-the-art 24-bit/192 kHz digital audio converters for the highest possible sound quality while recording and mixing. Check your mixes on multiple monitoring systems using four analog outputs with speaker switching technology for dual monitor setups. Or use the second set of outputs to add some analog signal processing to your mix bus for that classic studio sound.

Two independently controlled headphone outputs let you create custom mixes for multiple performers during recording sessions. A pair of virtual loopback inputs allow you to quickly monitor any combination of hardware input and software playback channels, saving you time setting up mixes.


The Scarlett 18i8 also comes bundled together with all of the creative tools you need to create your own music. 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.

Produce professional-sounding tracks with your choice of XLN Audio Addictive Keys virtual instruments. Tap into an endless source of inspiration with a free 3-month Splice Sounds subscription, where you can access millions of high-quality, royalty-free samples, loops, presets and more.

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.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

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.
