Be Ready For Anything

Record whatever you want, whenever you want

Our latest generation 18-in, 8-out USB interface is ideal for multi-instrumentalists, producers and small bands who want to record audio from a wide range of sources such as drums, guitars, keyboards and vocals. It's our most comprehensive desktop interface, giving you four mic preamps, round-trip latency as low as 2.74ms*, class-leading sound quality, and two separate headphone outputs, so you can give different monitoring settings to two artists, or an engineer and artist. It's also expandable over ADAT.

Delimit Your Studio

Don’t be limited by your interface’s connectivity. 18 separate inputs let you connect just about anything you want, and leave your instruments permanently set up and ready to record.

The four combination inputs on the front each have a natural-sounding Scarlett mic preamp, 48V phantom power and superior linear gain. Backed by 30 years of design experience, they guarantee low noise, minimal distortion and a dynamic range that is unrivalled in this class.

On the back are four more line inputs for connecting your synths, keyboards or mixers, and two additional S/PDIF inputs for recording digital sources. For even more inputs, connect an eight-channel mic pre like the Focusrite OctoPre Mk II, for a total of 16 analogue inputs with 12 preamps.

Separate Headphones

As well as two balanced analogue line outputs for connecting professional speakers, Scarlett 18i8 gives you two independent stereo headphone outputs, so you can give two artists (or an engineer and artist) their own cans and monitoring settings.

Revolutionise Your Workflow

An unrivalled round-trip latency as low as 2.74ms* completely revolutionises your workflow. You can work entirely inside your DAW for both overdubbing and playback, and use your favourite plugins while recording – whether it’s reverb on a vocal, a guitar amp simulator, or even virtual instruments live on stage. You’ll also get the best out of vocal performances, by applying real-time comfort reverb to headphones.

Unrivalled Sound Quality

We’ve been perfecting audio conversion for over 20 years. Our class-leading digital conversion operates at up to 24-bit and up to 192kHz, so you capture every nuance of every performance in crystal clear audio without any unwanted noise or hum, even when you’re playing softly.

Designed For Guitarists

We’ve redesigned Scarlett 18i8's instrument inputs and given them plenty of extra headroom, so you can handle extreme levels without any unwanted clipping or distortion. If you’re recording extra loud instruments, you can also engage the 10dB pad in Focusrite Control software.

New Generation – Better In Every Way

The latest generation Scarlett 18i8 is packed full of upgrades. It operates at sample rates all the way up to 192kHz with new super-low latency* that lets you record and monitor with software effects in real time.

We completely redesigned the instrument inputs so they can handle even the hottest guitar pick-ups, and we’ve made it easier than ever to set your levels accurately. We’ve also built in new analogue protection circuitry across the inputs and the outputs, to guard your interface against unwanted power surges.

*Super-low latency depends on your choice of software, settings and computer.

Used By the Best

What do Sam Smith, Foo Fighters and Massive Attack have in common? Not a lot, admittedly, but they all use Focusrite equipment because they agree with us that sound is everything.

Easily Find the Perfect Level

Clipped signals ruin good takes. Make sure you’re always recording at a good level, by keeping an eye on our signature gain halos. They glow a reassuring shade of green when you’re recording at the perfect level, and turn red to indicate overload.
