The scarlet heart of the studio

The Focusrite Scarlett 18i8, a USB audio interface for Mac and PC, has eight balanced line inputs for connecting synthesizers or other line-level audio sources, and four balanced outputs for monitoring. In addition, it features a digital stereo input and output in S/PDIF format and an eight-channel ADAT input. Four of the inputs are combined XLR/jack sockets and can thus also be used with microphones. The 18i8 is equipped with four high-grade Scarlett microphone preamps with switchable 48V phantom power, as well as the brand-new Air Mode. Electric guitars and basses can also be plugged in directly, as the impedance of the four front sockets can be set to Hi-Z. The Scarlett 18i8 also looks great and is very attractively priced. An audio interface provides a connection between a computer and various external devices. The computer in turn requires special software in order to process the incoming signals. Focusrite offers a selection of software you can use to get started, including the digital audio workstations (DAWs) Ableton Live Lite and ProTools Artist, and a three-month subscription to Splice Sounds. Focusrite’s Hitmaker Expansion software bundle is also included.

Love is in the “Air”

Focusrite’s outstanding reputation for building high-quality mic preamps has been established for over three decades now, and much of this expertise has been included in the third generation of Scarlett interfaces via the brand-new integrated Air Mode, which when selected opens up and brightens the high end in a way that is intended to emulate their classic ISA preamps – or, as the British manufacturer puts it, to provide “unique high-end detail for vocals and acoustic guitar”. Decades of experience really do speak for quality in this case, and the AD/DA converters provide optimum clarity and detail with a maximum bit depth of 24 bits and frequency rates of up to 192kHz.

The power of 18

The Focusrite Scarlett 18i8 is a compact desktop interface and is therefore particularly suited to project and professional studios. It is sturdily built yet lightweight and portable. The 18 flexibly designed inputs should be fit for any purpose, and the four outputs mean you can create an alternative monitoring mix or integrate outboard effects units. What is more, the integrated MIDI interface can be used to connect a master keyboard, for example, since a sound generator of four XLN Audio Addictive Keys is already included in the bundled software package.

About Focusrite

Founded in 1985 by Rupert Neve, Focusrite quickly made a name for itself with high-quality analogue consoles. Today, the company markets audio interfaces, mic preamps, consoles, analogue EQs, and channel strips as well as hardware and software for digital audio processing. The company is based in High Wycombe, England, and has won numerous industry awards. In addition to the Focusrite Pro line, the company also has subsidiaries that include Adam Audio, Novation, and iOS app creator Ampify Music.

Get started right away

The newly designed “gain halos” (the red and green LED rings around the gain controls on the front panel) are intended to make it easier to adjust gain settings, so that budding producers can start recording immediately after buying the interface. To make things simpler still, Focusrite has included a “Quick Start Tool” and put together an impressive and comprehensive package of free software, some in the box and some available for download, which includes Ableton Live Lite, Pro Tools Artist, Focusrite Red Plugin Suite, Focusrite Control, Softube Time and Tone Bundle, a three-month subscription to Splice Sounds, and a software tool of four XLN Audio Addictive Keys of your choice.

In the spotlight: Solo, 2i2, 4i4, 8i6, 18i8, and 18i20

The third generation of Scarlett interfaces comprises the Solo, 2i2, 4i4, 8i6, 18i8, and 18i20 as well as two bundles, the Solo Studio and 2i2 Studio, each of which includes a microphone and headphones. The abbreviations 2i2, 4i4, etc. specify the number of inputs and outputs. In other words, “2i2” stands for two (i)nputs and two outputs, and 4i4 accordingly stands for four (i)nputs and four outputs. The “Solo” bends the rules in this respect, since it actually features two inputs and two outputs – the name instead suggests that it is intended for solo artists or singer/songwriters.

Superb - A great upgrade on smaller versions.
LocoRoco 29.09.2021
I upgraded from the old Scarlett solo for two reasons - I needed more input and I needed an improved workflow.

This allows me to feel like I've got a little studio at my desk. I have my synths, mic and instrument cables all neatly plugged in and ready to go.

The software for setting up your output mix is a little complicated at first and doesn't seem to fit my screen perfectly, but it allows me to customize the 2 headphone mixes.

It fits on my rollout desk next to my midi keyboard like a dream.

I've had 0 dropouts or failures with it after 6 months of use.


Vic Rose 25.01.2021
A cool confident product with almost analogue appeal. I simply love touching this thing, the knobs are smooth and I get the same from a milimeters shift that I would get from a whole centimeter on other devices. 8 in 8 out with multiple headphone sockets this beast of home studios performs as good as it looks, once you update and register its software, do not attempt to plug and play without adding its digital components, you was warned.


More than enough
Folia Soundstudio 07.10.2022
The 3rd generation of Scarlett interfaces is simply best in its class. Clean sounding, stable working. The mixer is a bit limited, but I'm being spoiled by RME TotalMix, so I expect same functionality everywhere.

The only serious flaw that it sometimes causes issues, when you are working both with ASIO driver in your DAW and Windows driver for your system sounds at the same time. People report it online, I also encountered that.


Amazing interface
Omrikush 04.09.2021
no need to say much about the scarlet interface. had the 2!2 for many years now needed more inputs and that's the perfect choice . if you need more than the typical two input interface that's the one.
