OVERVIEW
Introduction
Thank you for purchasing this Second Generation Scarlett 2i2, one of the family of Focusrite
professional audio interfaces incorporating high quality Focusrite analogue pre-amplifiers. 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 Second Generation series of Scarlett interfaces, we have enhanced both the
performance and feature set including support for sample rates up to 192 kHz, improved mic preamp
performance with low noise and plenty of gain, and upgraded instrument inputs with additional
headroom for recording the loudest guitar parts without clipping. They are class compliant on Mac,
which 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 that 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 that you are fully aware of all the possibilities that 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 https://support.focusrite.com/, which contains a comprehensive collection of 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 Mac OS 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 amplifier and speakers, powered monitors, headphones,
analogue mixer or any other analogue audio equipment that you wish to use. Although all inputs and
outputs on the Scarlett 2i2 are routed directly to and from your DAW for recording and playback, you
can configure the routing within your DAW in order to meet your needs.

Connecting your Scarlett 2i2
IMPORTANT - WINDOWS USERS: Before you connect the Scarlett 2i2 to your
computer, please complete the software installation according to the instructions
on page 5. This will ensure that the hardware uses the correct drivers, and will
prevent unexpected behaviour.
The Scarlett 2i2 has a single USB 2.0 port (on the rear panel). Once the software installation
(if necessary) is complete, simply connect the Scarlett 2i2 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. It will not operate correctly with USB 1.0/1.1 ports.
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 installing the drivers (Windows only) and connecting the
hardware, 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 downloaded and activated
your software on-line. To install either DAW, download and save the desired installer file from your
registered Focusrite “My Products” page as described on page 5, and then run it, following all
on-screen instructions.
Operating instructions for both Pro Tools | First and Ableton Live Lite are beyond the scope of this
User Guide, but both applications include a full set of Help files.
Please note - your DAW may not automatically select the Scarlett 2i2 as its default I/O device. In this
case, you must manually select ‘Scarlett 2i2’ as the driver on your DAW’s Audio Setup* page.
Please refer to your DAW’s documentation (or Help files) if you are unsure where to select the ASIO
or Core Audio driver. The following example shows the correct configuration in the Ableton Live Lite
Preferences panel (Windows version shown).

8
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 examples below show Inputs 1 & 2 and Outputs 1 & 2
enabled in the Ableton Lite Audio Preferences.
*Typical name. Terminology may differ slightly between DAWs.

9
Examples of Usage
The Scarlett 2i2 is an excellent choice for several different recording and monitoring applications.
Some typical configurations are shown below.
Connecting a microphone or instrument
This setup illustrates the most typical configuration for recording with DAW software on your Mac or
PC. In this case, 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).

10
The front panel input sockets are “Combo” type, which accept either an XLR male connector (you will
probably have one on the end of your microphone cable) or a ¼” (6.35 mm) jack plug. If you are using
a capacitor (or “condenser”) microphone, you will need to turn on the 48 V phantom power. Phantom
power should NOT be on when other types of microphone – e.g., dynamic or ribbon - are in use.
Note the Scarlett 2i2 has no “Mic/line” switch – the Focusrite preamplifier stage is automatically
configured 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 LINE/INST switch next to the socket to INST if you are connecting
musical instrument (a guitar in the example) via an ordinary 2-pole (TS) guitar jack, or to LINE 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 fitted with a “Direct Monitoring” option, which overcomes this problem. Setting the
front panel DIRECT MONITOR control to ON 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.
When Direct Monitoring is set to ON, ensure that 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.

11
Connecting Scarlett 2i2 to loudspeakers
The ¼” jack outputs on the rear panel can be used to connect monitoring speakers. Self-powered
monitors (e.g., typical computer speakers) incorporate internal amplifiers with a volume control, and
may be connected directly. Larger, passive loudspeakers will require a separate stereo amplifier; in
this case, the outputs should be connected to the amplifier’s inputs.
Connecting active speakers
Connecting passive speakers

12
The line outputs are 3-pole (TRS) ¼” (6.35 mm) jack sockets, and are electronically balanced. Typical
consumer (hi-fi) amplifiers and small powered monitors will have unbalanced inputs, either on
phono (RCA) sockets, or via a 3.5 mm 3-pole jack plug intended for direct connection to a computer.
In either case, use a suitable connecting cable with jack plugs at one end.
Professional power amplifiers 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 that you always turn off (or turn down) monitoring
loudspeakers while recording, and use headphones when overdubbing.

The Front Panel includes the input connectors for Mic, Line and Instrument signals, as well as the
input gain and monitoring controls.
1. Inputs 1 & 2 – “Combo” type input sockets - connect microphones, instruments (e.g., guitar),
or line level signals via XLR or ¼” (6.35 mm) jacks as appropriate.
2. GAIN 1 and GAIN 2 – adjust the input gain for input signals on inputs 1 and 2 respectively. The
gain controls have concentric bi-colour LED ‘rings’ to confirm signal level: green indicates an
input level of at least -24 dBFS (i.e., ‘signal present’), the ring then turns red when signal level
reaches 0 dBFS, indicating digital clipping.
3. 48V – phantom power switch for mic inputs - enables 48 V phantom power at XLR contacts of
both Combo connectors.
4. LINE/INST – Line/Instrument level switches for each input – switches gain and input
impedance to suit instrument or line level signals.
5. MONITOR – main monitor output level control - sets the output level at the main (rear panel)
outputs 1 and 2.
6. USB LED – illuminates when the unit receives USB bus power and is confirmed by the
computer as connected and operating correctly.
7. DIRECT MONITOR – allows you to select how you monitor your live recording - either via the
DAW or directly (zero latency).
8. Headphone level – adjusts the output level at the front panel stereo headphone output.
9. Headphone socket – ¼” TRS output jack - connect your stereo headphones here.
