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 48 V 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. The interface also comes complete with the Focusrite Hitmaker Expansion, a comprehensive software package that essentially gives you everything you need to carry out every stage of the production process on your computer, from beginning to end.

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 192 kHz.

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 First, Focusrite Red Plugin Suite, Focusrite Plugin Collective, 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.

Hitmaker Expansion

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. The Hitmaker Expansion from Focusrite includes everything you need to get started here. At the core of the music production process here is the Ableton Live Lite digital audio workstation (DAW), and the package also includes tools for all of the relevant applications: Guitar sounds with Softube Marshall Silver Jubilee 2555, virtual instruments with XLN Audio Addictive Keys and Addictive Drums 2, vocal tuning options, effects, and of course mastering tools to ensure that your finished projects sound properly polished. With the Hitmaker Expansion, you therefore get both the interface itself and the entire range of tools you need in order to get the absolute best from what your interface has to offer.

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.

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.

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.


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.


the best you can get for this budget line
abarrote 23.02.2021
Definitely recommended. I researched for USB interfaces for a while and didn't want to spend a lot of money while getting good results at the same time. This is definitely an excellent choice for this price line. Couldn't be more happier!
