Introduction
Thank you for purchasing Scarlett 18i6, one in a family of Focusrite professional multi-channel USB 2.0 interfaces featuring high
quality Focusrite pre-amps. You now have a complete solution for routing high quality audio in and out of your computer.
This guide provides a detailed explanation of both the hardware and accompanying control software “Scarlett MixControl” to help you
achieve a thorough understanding of the product’s operational features. We recommend that both users who are new to computer
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 both Scarlett 18i6 and accompanying software have to offer.
If the main User Guide sections do not provide the information you need, be sure to consult http://www.focusrite.com/answerbase,
where you’ll fine a comprehensive list of common technical support queries regarding the product to date.
Basics
The Scarlett 18i6 hardware interface provides the means for connecting microphones, line-level signals, instrument-level signals,
and digital signals to your computer, which are then routed to your audio recording software / digital audio workstation (referred to
throughout this user guide as “DAW”).
All audio signals connected to the inputs, plus audio output from your computer programs are routed to the physical outputs for you
to connect to an amp and speakers, powered monitors, headphones, analogue/digital mixer, and any other studio equipment that you
wish to use. There are also connectors for sending and receiving MIDI.
The accompanying software application, Scarlett MixControl provides further recording, routing and monitoring options, as well as the
ability to control global hardware settings such as sample rate and synchronisation.
Scarlett MixControl software provides mixing and routing to and from the DAW, allowing control over which signals are sent from
the sequencer to each output. All inputs on the Scarlett 18i6 are routed directly to your DAW software for recording, but Scarlett
MixControl also allows you to route these signals to your monitors so that you can listen to the audio signals with zero latency - before
they arrive at your DAW.

Getting started
Before connecting Scarlett 18i6 to your computer, the software must be installed. This will ensure that the correct drivers are used,
thus preventing any unexpected behaviour.
Note on USB hubs
Scarlett 18i6 is a USB 2.0 device and must be connected to a compatible USB 2.0 port. If using a USB hub, it is essential that all other
devices connected to the hub are also USB 2.0 compatible. If any USB 1.0 / 1.1 devices are connected, the hub will be forced to run at
the legacy speed which may prevent the Scarlett 18i6 from working.
Scarlett 18i6 will use a significant amount of USB bandwidth (the amount of data transferred via USB). If connected to a USB hub
other devices connected to the hub may affect the performance of Scarlett 18i6. For example, if using a USB 2.0 hard drive for audio
sample playback (also transferring a large amount of data) this should not be connected to the same USB hub as Scarlett 18i6.
Therefore it is recommended, when possible, to connect Scarlett 18i6 directly to your computer USB port rather than through a USB
hub.
Powering the Scarlett 18i6
You must use the included power supply to use the Scarlett 18i6, it does not power from USB alone. This is because the analogue
and digital circuitry requires more power to run than the USB standard can provide.

Pre amp section
When connecting a microphone to Scarlett 18i6, connect an XLR cable to the combo inputs on the front panel. When connecting
either line level signal or instrument signal to the combo inputs, select either ‘Line’ or ‘Inst’ from the pre amp section.
Mixer section
The Scarlett MixControl software includes a total of six mixes, each with a maximum of 18 channels in the mix. Up to six mono mixes
or three stereo mixes, (or any combination of mono and stereo mixes) are available, making up a total of six mix channels.
The Mixer Section is used to create mixes for monitoring purposes. Created mixes do not affect how the audio inputs are routed to
the DAW, nor do they affect the audio level of the recorded signal. What is set up in the mixer section of Scarlett MixControl only
affects what is heard in the outputs of the mix.
The recording levels that are sent to the DAW are therefore only affected by the input gain settings on the Scarlett 18i6, not the mixer.
The mixer section is useful for creating different simultaneous mixes. For example, the recording engineer may wish to provide a
headphone monitor mix for the recording artist that is different to the mix heard in the monitor speakers, where the artist needs to
hear mainly the backing track, and a little of the recorded input signal, whereas the engineer needs to hear mainly the recording
artist’s signal and a little of the backing track.
A separate mix can be created for both artist and engineer with the exact levels desired. Each independent mix is created on a
different mix tab.
Mixer tab
Each mix can be selected by clicking on the corresponding mixer tab.
12
Input channel
Here is a picture of two mixer input channels. Below is a description of every component of a mixer channel.
Audio source select
When there is no input to a mixer channel, it will display “Off”.
Clicking on the “Off” region brings up a list of all available inputs that can be fed to the
channel. All analogue (labelled ‘Anlg’), digital inputs (S/PDIF and ADAT), and DAW outputs
are available.
When selecting a source on a stereo channel, if an odd-numbered input is chosen for the
left channel, the next even number input is auto selected for right, and vice versa.
Note that if an input has already been taken, it will be greyed out and cannot be selected
again. The input needs to be deselected from the track where it is already taken and then
re-selected on the desired track.
To get sounds from the DAW or other computer applications into the mixer, ‘DAW 1’ and
‘DAW 2’ should be selected on a stereo input track.
13
Pan slider
A Pan slider is used to position the audio signal anywhere between the left and right speakers.
Moving the horizontal slider from left to right will move the audio signal from left to right within the stereo field, i.e.,
the signal is faded between two audio outputs such as monitor L and R.
When used with a stereo track, the slider affects the audio signal such that when fully left, only the left channel is
heard. When fully right, only the right channel is heard
Fader
Use the fader to set the level of your audio signal for monitoring within the current mixer.
Click the fader with your mouse and drag to any position. Double click on the fader to set it to 0.
Fader range is from -∞ to +6dB with the current fader level displayed in the box below.
Holding the Shift key whilst moving the fader allows for fine adjustment of fader levels.
Meter
The meter shows the signal level of the source input to the channel. The recent maximum signal level is displayed in the box below.
The metering is always pre-fade, showing the level of the signal at the input. Therefore, the fader level has no effect on
the metering.
There is a clip light at the top of the meter. If this red portion at the top of the meter lights up, then the signal level is too
high. The signal level must be turned down by either using the gain knobs on the front panel for the analogue inputs,
using the gain on the external devices connected to the digital inputs or using the gain within the DAW.
Once the gains are lowered, click on the red portion to reset the clip light.
Mute
Pressing this button mutes the signal. Red indicates that mute is active.
Solo
Pressing this button solos the signal. The level of the fader will affect the level of the solo signal.
Yellow Indicates that solo is active.
PFL (Pre-fade listen)
14
Pressing this button solos the signal and automatically routes it to monitor 1 and 2. The level of the soloed signal is pre-
fade (i.e. it will not be affected by the level of the fader). Green indicates that PFL is active.
Stereo
Pressing this button combines two mono channels into one stereo channel.
Track name
As a default, each track is given a corresponding number as a name. Double click to rename the track to something more useful such
as ‘Vocal Mic’.
Mix output channel
The output channel of the mix is where all the input channels are routed to and mixed together. The output channel
provides control of the overall level of the entire mix. It is possible to send a mix to any or all hardware outputs; if
a single output is selected this is displayed at the top of the output channel. “Many…” will be displayed if multiple
outputs are selected.
The output channel can be either mono or stereo depending on the status of the stereo button. When the channel
is set to stereo, the tab for that mix doubles in size. This is because the stereo version takes up two channels of the
available total output channel count.
Note that when the solo button on an output channel is pressed, that channel (i.e. the whole mix) is soloed and
routed to Monitor outputs 1 and 2. This is a non-latching button.
The current mix can be named by typing the desired name in the text field below the output channel. The given
name appears in the mix tab. For example, Mix 1 can be renamed “Monitor Mix”, and Mix 5 named “Headphone 1
Mix”.
To copy an existing mix to another mix, simply click on “Copy Mix To...” and select the mix to which a copy is
required. Note that a stereo mix can only be copied to another stereo mix, and a mono mix to another mono mix.
Therefore it is important to make sure that the output channels are correctly set up to either stereo or mono before
copying the mix.
Clicking “Sel…” will show a drop down menu of the available output destinations for the selected
mix. Selecting an output in this menu will choose the output destination for the selected mix.
15
Routing section
The routing section allows the setting up of audio sources which are to be routed directly to physical outputs.
The routing section displays every physical output on the Scarlett 18i6. An audio stream can be routed to an output using the
dropdown menu to the left of the output.
Clicking on the box to the left of the output label will bring up a list of all available audio output sources.
The available sources include:
• All inputs (Analogue 1 - 8 S/PDIF 1 - 2, ADAT 1 - 8)
• All DAW playback streams (DAW 1 - 6)
• All mixes from the mixer (Mix 1 - 6)
If the mix has been named (by clicking in the track name section – see previous chapter) then this name is displayed as the mix
source name.
Note that the routing section is linked to the selection made for the output channel destination set-up in the mixer.
Routing audio to the headphones
The headphone symbols in the router denotes the source for the left and right ears of the headphones.
16
Routing presets
Routing presets are provided as a starting point for the creation of routing and mixer set-ups.
Clear
This turns off all output routing. This can be used to reset the routing for the complete restart of a configuration, meaning that there is
no requirement to manually reset the routing.
DAW Tracking
‘DAW Tracking’ is used for the initial recording process. It will automatically output DAW 1 and 2 to be sent to all line outputs, the main
monitors (1+2) and headphones. All input channels must therefore be monitored from within the DAW application.
Zero Latency Tracking
Zero Latency Tracking is used for the recording process. It will automatically output Mix 1 and 2 to all the line outputs, routing to the
main monitors and to the headphones simultaneously. Line inputs and DAW outputs must be set up in Mix 1 so that the monitor
sources can be monitored with zero latency. It is important that the same signals are not monitored from within the DAW at the same
time, otherwise the same signal will be monitored twice (once direct from Scarlett MixControl AND a second time (with latency) from
the DAW.)
17
Monitor section
The output levels of the monitor outputs and headphone outputs are configured in the Monitor Section. Scarlett 18i6 can be set up so
that the audio sent to the line outputs are controlled by the software volume dial; independent of the software volume dial; or muted.
Monitor control enable buttons
The monitor control enable buttons indicate which outputs are controlled by the monitor section on the GUI directly below the
four buttons. The Scarlett 18i6 can be set up so that there is control of monitor speaker and headphone volume levels together or
independently
(All digital output levels are unaffected by the monitor section in Scarlett MixControl. The output levels set up in the DAW are used to
control digital output levels).
Each button can be set to one of three possible states:
Blue - this output is controlled by the below monitor section
Red - this output is not controlled by the below monitor section and it is muted
Grey - this output is not controlled by the below monitor section and it is at full level.
To set a button to its grey state, SHIFT + Click the button
WARNING: When a monitor control button is set to ‘Grey’, the signal routed to that output will be played back at full level.
This may potentially result in a very loud signal being sent to your monitor speakers, headphones or other equipment.
Therefore is is important to be cautious when setting levels (in the DAW or the Scarlett MixControl Mixer) before setting the monitor
button to Grey.
18
Monitor section controls
The following controls in the Monitor Section will affect those channels that have been selected for monitor control (indicated with a
blue button, see above).
Monitor level control knob
The output level of all assigned outputs is set using this knob. The output level can be adjusted using the mouse and will affect all
assigned outputs (as indicated with a blue button). The dB display below shows the current level to which the monitor knob is set.
Note that the front panel Monitor control affects only outputs 1 and 2, and is an additional volume control on top of the monitor level
set in Scarlett MixControl software.
Dim switch
Attenuates the output level by 18dB
Mute switch
Mutes the output
Left mute switch
Mutes the left output
Right mute switch
Mutes the right output
Remember that these dim and mute buttons only affect the outputs selected for control (i.e. blue) in the monitor control section.
19
Device status section
The Device status section shows information about the sample rate, synchronisation and driver status of
Scarlett 18i6. The desired sample rate can be set as well as external synchronisation options for using
Scarlett 18i6 with external digital devices.
Sample rate display
The sample rate display shows the current sample rate at which the Scarlett 18i6 is running. To change the
sample rate, click on the red sample rate value and select 44.1kHz, 48kHz, 88.2kHz, or 96kHz,
Note: you must quit your DAW application BEFORE you make sample rate changes to prevent any undesirable side-effects in your
DAW!
Sync source display
This sync source display shows the currently selected sync source. To change the sync source, click on the
red sync source value and select S/PDIF, ADAT or Internal.
Sync status display
The sync status display shows “Locked” when the Scarlett 18i6 has successfully locked to the specified Sync Source. If “No Lock”
is seen, then the unit has been unable to lock to an external S/PDIF or ADAT signal. If this is the case, then please check that digital
cables are secure in their input sockets and that the external digital devices have been set up as sync master devices.
USB driver
The USB driver display shows “Connected” when the Scarlett 18i6 is connected to the computer via USB.

Settings menu (Windows only)
The settings menu is a drop down menu containing driver latency settings. Macintosh OSX users will change driver latency from
within their chosen DAW or music software application. PC users set the latency settings here.
ASIO buffer size
The ASIO buffer size sets the driver latency for your DAW or music software application. A
small buffer size will in result in lower latency at the expense of increased CPU usage. A high
buffer size will result in a higher latency but with lower CPU usage. If you are using lots of
virtual instruments and effects processing in your DAW project and the CPU usage is high,
then increase the buffer size to permit lower CPU usage.
File menu
Mac
Windows
Open - opens a ‘File Open’ window allowing selection of any pre-saved Scarlett MixControl set-ups.
Save - opens a ‘File Save’ window allowing selection of a location into which your Scarlett MixControl set-up can be saved.
Subsequent saves overwrite the original file.
Save As - opens a ‘File Save’ window allowing selection of a location into which your Scarlett MixControl set-up can be saved. Use
this option if you want to keep your original saved set-up and create a new one with a different name.
Restore Factory Defaults - causes the Scarlett 18i6 to revert to the original default state in which it left the factory.
Clear All Settings - causes the Scarlett 18i6 to reset all mixer and routing settings. This can be used to globally reset all mixer,
routing, and monitor settings, allowing creation of a new set-up from scratch.
As can be seen from the above screen shots, ‘Open’, ‘Save’ and ‘Save As’ all have keyboard shortcuts. These are standard shortcuts
for their respective functions, when regularly changing settings for various sessions, the shortcuts will reduce your set-up time.
