OVERVIEW
Introduction
Thank you for purchasing this Third Generation Scarlett 2i2, one of the family of Focusrite professional
computer audio interfaces incorporating high quality Focusrite analogue preamps. You now have a
simple and compact solution for routing high quality audio to and from your computer and you will
also be able to download some exciting new software plug-ins once you’ve registered the product.
In developing the Third Generation series of Scarlett interfaces, we have made further improvements
to both performance and features. Audio specications have been upgraded throughout the unit to
give you greater dynamic range and even lower noise and distortion; additionally, the mic preamp
now accepts higher input levels.
An important enhancement is the inclusion of Focusrite’s AIR function. Individually selectable on each
channel, AIR subtly modies the preamp’s frequency response to model the sonic characteristics
of our classic transformer-based ISA microphone preamps. When recording with good quality
microphones, you will notice an enhanced clarity and denition in the important mid to high frequency
range, just where it is most needed for vocals and many acoustic instruments.
We have also enhanced the Direct Monitor feature found on previous Scarletts: now you can monitor
as you record in either mono or stereo, with zero latency. Third Generation Scarlett interfaces are
class compliant on macOS: this means they are plug-and-play, so no need to install a driver if you
are a Mac user.
This User Guide provides a detailed explanation of the hardware to help you achieve a thorough
understanding of the product’s operational features. We recommend both users who are new to
computer-based recording, as well as more experienced users, take the time to read through the
User Guide so you are fully aware of all the possibilities the Scarlett 2i2 and accompanying software
has to offer. If the main User Guide sections do not provide the information you need, be sure to
consult support.focusrite.com, which contains a comprehensive collection of answers to common
technical support queries.
Features
The Scarlett 2i2 hardware interface provides the means for connecting microphones, musical
instruments or line level audio signals to a computer running macOS or Windows. The signals at the
physical inputs can be routed to your audio recording software / digital audio workstation (referred
to throughout this user guide as the “DAW”) at up to 24-bit, 192 kHz resolution; similarly, the DAW’s
monitor or recorded output will appear at the unit’s physical outputs.
The physical outputs can be connected to an amplier and speakers, powered monitors, headphones,
analogue mixer or any other analogue audio equipment you wish to use.

System requirements
The easiest way to check your computer’s operating system (OS) is compatible with your Scarlett is
to use our Help Centre’s compatibility articles:
support.focusrite.com/hc/categories/200693655
As new OS versions become available over time, you can continue to check for further compatibility
information by searching our Help Centre at support.focusrite.com.

GETTING STARTED
With the Third Generation, Scarlett interfaces introduce a new, faster way of getting up and running,
using the Scarlett Quick Start tool. All you need to do is connect your Scarlett 2i2 to your computer.
Once connected, you will see the device is recognised by your PC or Mac and the Quick Start tool will
guide you through the process from there.
IMPORTANT: The Scarlett 2i2 has a single USB 2.0 Type C port (on the rear panel): connect it
to your computer using the USB cable provided. Note that Scarlett 2i2 is a USB 2.0 device, and
thus the USB connection requires a USB 2.0+ compliant port on your computer.
The Scarlett 2i2 does not need a separate power supply; It gets its power from your computer
via the USB connection. However, we recommend when using a laptop, the laptop is powered
using its AC adaptor, as otherwise the battery will drain faster than when powering from the
laptop alone.
Your computer will initially treat your Scarlett as a Mass Storage Device (MSD), and during its rst
connection, the Scarlett will be in “Easy Start mode”.
Quick Start Tool
We have tried to make registering your Scarlett 2i2 as simple as possible. The steps are designed to
be self explanatory, but we have described each step below, so you can see how they should appear
on either a PC or a Mac.
Mac users only:
On connecting your Scarlett 2i2 to your Mac, a Scarlett icon will appear on the desktop:
6
Double-click on the icon to open the Finder window shown below:
Double-click on the “Click Here to Get Started.url” icon. This will redirect you to the Focusrite website,
where we recommend you register your device:
Click on “Let’s get you started”, and you’ll see a form which will be partly prelled for you automatically.
When you submit the form, you’ll see options to go straight to the downloads to get the software for
your Scarlett, or to follow a step by step setup guide based on how you want to use your Scarlett.
Once you have installed the Focusrite Control software to set up and congure your interface, the
Scarlett will be switched out of Easy Start mode so it no longer appears as a Mass Storage Device
when connected to your computer.
Your OS should switch the computer’s default audio inputs and outputs to the Scarlett. To verify this,
go to
System Preferences > Sound, and ensure the input and output are set to Scarlett 2i2.
For detailed setup options on a Mac, open
Applications > Utilities > Audio MIDI Setup.
7
Windows only:
On connecting your Scarlett 2i2 to your PC, a Scarlett icon will appear on the desktop:
(Note that the drive letter may be something other than F:, depending other devices connected to
your PC).
Double-click on the pop-up message to open the dialogue box shown below:
Double-click on “Open folder to view les”: this will open an Explorer window:
8
Double-click “Click Here to Get Started”. This will redirect you to the Focusrite website, where we
recommend you register your device:
Click on “Let’s get you started”, and you’ll see a form which will be partly prelled for you automatically.
When you submit the form, you’ll see options to go straight to the downloads to get the software for
your Scarlett, or to follow a step by step setup guide based on how you want to use your Scarlett.
Once you have installed the Focusrite Control software to set up and congure your interface, the
Scarlett will be switched out of Easy Start mode so it no longer appears as a Mass Storage Device
when connected to your computer.
Your OS should switch the computer’s default audio inputs and outputs to be the Scarlett. To verify
this, right click on the Sound icon on the taskbar and select Sound Settings, and set the Scarlett
as the Input and Output Device.

All users:
Note that a second le - “More Info & FAQs” - is also available during the initial set-up process. This
le contains some additional information about the Focusrite Quick Start tool which you may nd
helpful if you have any issues with the procedure.
Once registered, you will have immediate access to the following resources:
• Focusrite Control (Mac and Windows versions available) - see NOTE below
• Multi-language User Guides
You can nd the licence codes and links for the optional bundled software in your Focusrite account.
To nd out what bundled software is included with Scarlett 3rd generation, please visit our website:
focusrite.com/scarlett
NOTE: Installing Focusrite Control will also install the correct driver for your device. Focusrite Control
is available to download at any time, even without registering: see “Manual Registration” below.
Manual Registration
If you decide to register your Scarlet at a later date you can do so at:
customer.focusrite.com/register
You will need to enter the Serial Number manually: this number can be found on the base of the
interface itself, and also on the barcode label on the side of the box.
We recommend you download and install our Focusrite Control application, as this will disable Easy
Start mode and unlock the full potential of the interface. Initially, when in Easy Start mode, the
interface will function at sample rates up to 48 kHz. Once Focusrite Control is installed on your
computer, you can work at sample rates up to 192 kHz.
If you decide not to download and install Focusrite Control immediately, it can be downloaded at any
time from:
customer.focusrite.com/support/downloads
To force your Scarlett out of Easy Start mode without rst registering it, connect it to your computer
and press and hold the 48V button for ve seconds. This will ensure your Scarlett has full functionality.
Please bear in mind that should you wish to register your Scarlett after taking this action, you will
need to so manually, as explained above.

Audio Setup in your DAW
The Scarlett 2i2 is compatible with any Windows-based DAW that supports ASIO or WDM and any
Mac-based DAW that uses Core Audio. After following the Getting Started procedure described
above, you can start using the Scarlett 2i2 with the DAW of your choice.
To allow you to get started if you do not already have a DAW application installed on your computer,
both Pro Tools | First and Ableton Live Lite are included; these will be available to you once you’ve
registered your Scarlett 2i2. If you need help installing either DAW, please visit our Getting Started
pages at focusrite.com/get-started, where Getting Started videos are available.
Operating instructions for Pro Tools | First and Ableton Live Lite are beyond the scope of this User
Guide, but both applications include a full set of Help les. Instructions are also available at avid.com
and ableton.com respectively.
Please note - your DAW may not automatically select the Scarlett 2i2 as its default I/O device. You must
manually select Focusrite USB ASIO as the driver on your DAW’s Audio Setup* page. Please refer
to your DAW’s documentation (or Help les) if you are unsure where to select the ASIO or Core Audio
driver. The example below shows the correct conguration in the Ableton Live Lite Preferences
panel (Windows version shown).
* Typical names. Terminology may differ between DAWs
11
Once the Scarlett 2i2 is set as the preferred Audio Device* in your DAW, Inputs 1 & 2 and Outputs 1 &
2 will appear in your DAW’s Audio I/O preferences. Depending on your DAW, you may need to enable
certain inputs or outputs before use.
The two screenshots below show Inputs 1 & 2 and Outputs 1 & 2 enabled Input and Output Cong in
Ableton Live Lite’s Audio Preferences.

Examples of Usage
The Scarlett 2i2 is an excellent choice for several different recording and monitoring applications.
Some typical congurations are shown below.
Connecting a microphone or instrument
RIGHT LEFT
This setup shows the most typical conguration for recording with DAW software on your Mac or PC.
You might record guitar through Input 1 and vocals through Input 2 into your DAW, while monitoring
the playback from the DAW via headphones (or speakers).
The front panel input sockets are “Combo” type, which accept either an XLR male connector or a ¼”
(6.35 mm) jack plug.
The full gain range of the microphone preamplier is only available to a mic connected via the XLR
contacts. If your microphone has an XLR plug on the end of the cable, you can simply plug it in. If it
is a “condenser” microphone, you will need to turn on the 48 volt phantom power for it to work. Most
modern microphones of other types, e.g., dynamic or ribbon, will not be damaged by the inadvertent
application of phantom power, but note some older mics may be; if you have any doubt, please check
the specication of your mic to ensure it is safe to use.
13
If your mic has a jack plug on the end of the cable, it will require an adaptor to make it usable with
the XLR part of the Combo connector. Inserting the jack plug will congure the preamp with reduced
gain, which is likely to be insufcient for the mic (see below). Mics intended for use with computer
sound cards may also require a much lower phantom power voltage, so an adaptor specic to the
mic type should be obtained in this case.
The Scarlett 2i2 has no “Mic/line” switch – the Focusrite preamp stage is automatically congured
for a microphone when you plug an XLR into the input, and for a line or instrument when you connect
a jack plug. Set the INST switch ON (‘INST’ illuminates red) if you are connecting musical instrument,
e.g., a guitar in the example, using an ordinary 2-pole (TS) guitar jack. Set the INST switch to OFF if
you are connecting a line level source such as a keyboard, synthesiser or the balanced output of an
external audio mixer via a 3-pole (TRS) jack. Note the Combo connector accepts both TRS and TS
types of jack plug.
Using Direct Monitoring
You will frequently hear the term “latency” used in connection with digital audio systems. In the case
of the simple DAW recording application described above, latency will be the time it takes for your
input signals to pass through your computer and audio software. Latency can be a problem for a
performer who wishes to record while monitoring their input signals.
The Scarlett 2i2 is tted with a “Direct Monitoring” option, which overcomes this problem. Setting the
front panel DIRECT MONITOR control to either MONO
or STEREO will route your input signals
directly to the Scarlett 2i2’s headphone and main monitor outputs. This enables you to hear yourself
with zero latency – i.e., in “real time” – along with the computer playback. The input signals to your
computer are not affected in any way by this setting.
In MONO mode, Inputs 1 and 2 are routed equally to the two outputs (both the rear panel outputs
and headphones) so they both appear in the centre of the stereo image. This is useful when you are
recording two separate instruments or an instrument and a vocal, where there is no need for the two
signals to be specically located in the stereo image. Further examples would be an acoustic and an
electric guitar, a bass which is both mic’d and DI’d or two separate mics differently positioned on a
guitar amplier.
In STEREO mode, Input 1 is routed to the left output channel and Input 2 to the right. Use this mode
if you are recording something inherently stereo in nature. Monitoring in stereo will give you a more
accurate impression of the sound stage. Examples are any situation where two microphones are
being used to deliberately capture a stereo image such as a pair of overhead drum mics, a single
stereo mic recording an orchestra or other ensemble, or the stereo outputs of an electronic source
such as a piano, synthesiser or FX unit.
When using Direct Monitoring, ensure your DAW software is not set to route its input (what you
are currently recording) to its output. If it is, you will hear yourself “twice”, with one signal audibly
delayed as an echo.
Monitoring with DIRECT MONITOR set to OFF can be useful when using an FX plug-in to your DAW to
create a stereo effect which contributes to the live performance. In this way, you will be able to hear
exactly what is being recorded, complete with the FX. However, some latency may result, the amount
depending on the DAW’s buffer size and processing power of the computer.

Connecting Scarlett 2i2 to loudspeakers
You can use the ¼” jack outputs on the rear panel to connect monitor speakers. Active monitors
have internal ampliers with a volume control, and can be connected directly. Passive loudspeakers
require a separate amplier; the rear panel outputs should be connected to the amplier’s inputs.
RIGHT LEFT
RIGHT LEFT
The line outputs are 3-pole (TRS) ¼” (6.35 mm) jack sockets, and are electronically balanced. Typical
consumer (Hi-Fi) ampliers and small active monitors have unbalanced inputs, either on phono
(RCA) sockets, or a 3.5 mm TRS jack plug to connect to a computer. In either case, use a suitable
connecting cable with jack plugs at one end.
Professional power ampliers will generally have balanced inputs; we highly recommend using
balanced cables to connect these to the outputs of the Scarlett 2i2.
NOTE: You run the risk of creating an audio feedback loop if loudspeakers are active when you are
monitoring a microphone! We recommend you always turn off (or turn down) monitoring loudspeakers
while recording, and use headphones when overdubbing.

1. Inputs 1 & 2 – “Combo” input sockets - connect microphones, instruments (e.g., guitar), or
line level signals here. Combo sockets accept both XLR and ¼” (6.35 mm) jacks. Microphones
connect using XLR plugs: instruments and line level signals should be connected via ¼” (6.35
mm) jack plugs of either TS or TRS type. The preamp gain is appropriate for microphones
when an XLR plug is inserted, and for higher level signals when a jack plug is inserted. Do not
connect anything other than a microphone - e.g., the output of a sound module or FX unit - via
an XLR plug, as the signal level will overload the preamp, resulting in distortion; , if phantom
power is enabled, you may damage your equipment.
2. GAIN 1 and GAIN 2 – adjusts the preamp gain for signals on inputs 1 and 2 respectively. The
gain controls have tri-colour LED ‘rings’ to conrm signal level: green indicates an input level
of at least -24 dBFS (i.e., ‘signal present’), the ring turns amber at -6 dBFS to indicate the
signal is close to clipping, and nally to red at 0 dBFS (digital clipping).
3. 48V – phantom power switch for mic inputs - enables 48 V phantom power at XLR contacts of
both Combo connectors.
4. INST – Line/Instrument level switches for each input which alter gain and input impedance to
suit either instrument or line level signals. ‘INST’ illuminates red when Instrument mode is
selected. You can also enable INST from Focusrite Control.
5. AIR – two switches enabling AIR mode for each input. AIR modies the frequency response of
the input stage to model the classic, transformer-based Focusrite ISA microphone preamps.
‘AIR’ illuminates yellow when the mode is selected. Note that AIR may also be selected from
Focusrite Control.
6. MONITOR – main monitor output level control - sets the output level at the main (rear panel)
outputs LEFT and RIGHT.
7.
USB LED – a green LED illuminates when the Scarlett is connected and recognised by
your computer.

8. DIRECT MONITOR – this switch routes the inputs directly to the outputs with three different
settings: OFF, MONO and STEREO. When set to OFF, monitoring of input sources is via the
DAW; in MONO or STEREO, monitoring is taken directly from the preamp inputs so is free of
any latency. The symbols
or illuminate green to indicate selection of mono and stereo
modes respectively. When Direct Monitor is on, the signal is combined with software playback.
9.
Headphone level – adjusts the output level at the front panel stereo headphone output.
10.
Headphone socket – ¼” TRS output jack. If your headphones have a ¼” TRS
jack plug, connect them directly; if they have a 3.5 mm TRS “mini jack”, use a
TRS ¼”-to-3.5 mm jack adaptor. Note that headphones tted with 4-pole TRRS plugs will not
operate correctly.
