Front Panel In Depth
This section covers all the features on your Scarlett Solo’s front panel, what
they do, how you might use them and how they work in Focusrite Control 2.
Setting Preamp Input Gain
The preamp input gain controls how much signal you are sending into your
computer and recording software.
It’s essential to set a good level for the preamp input gain so you get the
best quality recording. If the preamp input gain is too low your signal will
be too quiet and when you try and boost its level later you may hear noise in
the recording; if the preamp input gain is too high you might ‘clip’ the input
and hear harsh distortion in your recording.
The Scarlett Solo has two analogue gain controls for preamp 1 (Line/Inst) and
preamp 2 (Microphone).
To control the input gain, turn the gain control for the preamp you are using
clockwise to increase the level or anti-clockwise to decrease the level.
When you send a signal into your preamp, the Gain Halo lights green, amber or
red to show the signal level going into your computer.
· Green shows your signal level is good. · Amber shows your signal is pre-
clip, any higher and you are likely to clip the input · Red shows your signal
has clipped, you should reduce the gain.
This diagram shows the meters at different levels to show the input signal
level:
Software Meters
In the same way as the input meters on your Scarlett Solo’s front panel, you
can see the incoming signal on the meters in Focusrite Control 2 to set the
correct preamp gain.
As the signal gets louder the meter in Focusrite Control 2 lights from green
to amber (pre-clip).
The indicator above the meter shows you the peak level (in -dBFS), the highest level on this track since you started monitoring the input. When you hover over the Peak level Meter you can click to Reset the value.
1. No input signal 2. -42 dBFS 3. -36 dBFS 4. -24 dBFS 5. -18 dBFS 6. -12
dBFS 7. -6 dBFS 8. 0 dBFS, clipping – turn down the input gain to avoid
distortion and clipping.

Waiting for an input signal.
The input signal has reached -18.5dB.
Scarlett Solo 4th Gen Studio Pack User Guide
48V (Phantom Power) Software Control
To enable 48V (Phantom Power) from Focusrite Control 2 click the +48V button.
This is the same as pressing the 48V button on the Scarlett Solo hardware.
Click to Reset the Peak Level meter.
When you overload the preamp, with too much input signal, or by adding too
much gain, the Peak Level Meter lights red. Hover over the Peak Level Meter
and click to Reset the value.
+48V Phantom Power off
+48V Phantom Power on
Important If you accidentally send 48V phantom power to the wrong input, most modern microphones of other types, e.g., dynamic or ribbon, will not be damaged, but some older microphones may be. If you’re unsure, please check your microphone’s user guide to ensure it is safe to use with 48V phantom power.
The Input has clipped.
Click to Reset the Peak Level Meter after clipping.
48V Button (Phantom Power)
48V, also commonly referred to as ‘Phantom Power’, sends 48 Volts from your
interface’s XLR connector to devices needing power to work. The most common
use is sending power to condenser microphones, but you may also need 48V for
inline mic preamps, active dynamic microphones and active DI boxes.
To turn on 48V:
1. Connect your microphone, or another powered device, to the XLR input on
your interface using an XLR cable. 48V is not sent to the 6.35mm (1/4″) jack
input.
2. Turn down that preamp’s gain control to avoid any unwanted pops and
clicks. 3. Press the 48V button (or the corresponding software button)
48v lights green to show it’s enabled. 48V phantom power is now being sent to
the XLR input on your Scarlett and to any device connected to the XLR input.

Scarlett Solo 4th Gen Studio Pack User Guide
Inst (Instrument) Button and Line Level Inputs
The Inst (Instrument) button only affects the 6.35mm (1/4″) line input for the
selected channel. It changes it from an input suitable for line-level devices
to an input better suited for instrumentlevel devices.
To enable, or disable, instrument mode for the 6.35mm (1/4″) jack input, press
the Inst button once. Green shows Inst is enabled, and white shows Inst is
disabled. When you enable Inst and connect a jack to your Scarlett, the
minimum gain for the input is changed to +7dB.
Air Modes
Air lets you change your Scarlett’s preamp sound with two different modes; Air
Presence or Air Presence and Harmonic Drive.
Air is only available for the microphone input.
To enable Air, select your input, press the Air button once for Air Presence,
again for Air Presence and Harmonic drive and again to turn off. The Air LED
changes colour to show which mode you have selected:
Note When the Inst light is white, the 6.35mm jack input is at line level.

Scarlett Solo 4th Gen Studio Pack User Guide
Output Control
Output controls the signals going to the first two Outputs on the back of your
Scarlett, the outputs you’d most often connect to speakers.
The Output control sets the level at the outputs from nothing (fully anti-
clockwise) to full-scale output (fully clockwise).
Direct Monitor Adjustment
From Focusrite Control 2 you can enable and adjust the Direct Monitor mix to
balance your inputs with the Playback channels from your software.
To enable Direct Monitor click on the Direct tab in Focusrite Control 2 and
click the Direct Monitor software switch at the top of the tab. The switch
lights green and Direct lights green on your Scarlett Solo’s front panel.
Speaker Output Calibration On some occasions, you may still hear sound from
your monitor speakers when the Output control is fully anti-clockwise, you can
adjust your monitor levels to resolve this:
1. Turn down your interface’s Output control and your monitors’ level
control. 2. Turn the Output control to maximum (or just below maximum). 3.
Play sound from your system. 4. Turn up your monitors’ level controls until
the level is the loudest you need.
You should no longer hear sound when the Output control is at its minimum. You
also have more control over the level with the full range of the Output
control. By setting it at just below the maximum, you also have a little extra
volume if you need it, or want to listen to sounds at a louder-than-normal
level.
Direct Monitor Button
Direct Monitor
allows you to hear the signals connected to your interface’s inputs
without them going through your computer. This means you will hear the inputs without any
latency and without effects.
You might use Direct Monitoring if you’re experiencing latency or a delay between making a sound and hearing it back from your software, or if you want to hear the signal going into your Scarlett, instead of after software with effects and plugins changing the way it sounds.
When Direct Monitor is off, the Direct icon lights white, to turn on direct monitoring, press the Direct button once and the Direct icon lights green.
Direct Monitor Off
Direct Monitor on and Analogue 2 reduced in level
To adjust your Direct Monitor mix:
1. Open Focusrite Control 2. 2. Click on the Direct tab.
Direct monitor off.
Direct monitor on.
3. Use the Mixer Channels, (faders, Mute and Solo buttons) to adjust the levels for Analogue 1, Analogue 2 and Playback 1-2. The final meter under Direct Monitor shows the combined level going to your monitor and headphone outputs.
14
Using the Mixer Channels Each mixer channel has a number of functions.
Scarlett Solo 4th Gen Studio Pack User Guide
Headphone Output
1. Mix Channel Name This shows the name of the mixer input.
2. Fader The Fader adjusts the level going to your Mix destination. Alt, option or double-click to reset. The faders have no effect on the sources you are currently recording.
3. Meter This shows you the channel’s level, in dBFS. Green shows a good level and amber means the level is very high. You’ll see two meters for stereo channels, one for each left and right side. The meter shows the level post- fader, the fader setting will affect the meter.
4. Mute and Solo
Mute – Click to silence the channel in the Mix. The Mute button lights blue enabled. You can Mute multiple channels simultaneously.
when
Solo – Click to solo the track by silencing all other channels in the Mix. The Solo
button lights yellow when enabled. Enabling Solo on multiple channels silences any channels without Solo enabled, i.e. you will hear all the Solo’d channels. If you enable both Mute and Solo, the last clicked option takes priority.
The headphone output is a 6.35mm (¼”) TRS jack. Many headphones have a 3.5mm
TRS jack, to connect them to your Scarlett Solo you must use a TRS 6.35mm to
3.5mm adaptor. The control above the headphone output controls the level going
to your headphones. Some higher impedance headphones may be quiet using them
with a Scarlett Solo, we recommend using headphones with an impedance up to
300.
Note Some headphones and jack adaptors may have TS or TRRS connectors, for
example, if they have a microphone or volume control built into the cable.
It’s unlikely these headphones will work properly. If you’re having issues,
use headphones and a jack adaptor with TRS jack connectors.

CM25 MkIII Microphone
The Scarlett CM25 MkIII microphone with the Scarlett Studio pack is a
condenser mic ideal for recording studio-quality vocals and most acoustic
instruments.
You can use the CM25 MKIII to record almost anything, but you’ll love how it
sounds on vocals and guitar thanks to its bright, clear, detailed character.
We’ve also included a windscreen for the CM25 MKIII to reduce plosives and
wind noise when you’re recording vocals or spoken word.
To use the CM25 MkIII with your Scarlett Solo:
1. Turn the input gain for the channel to minimum and turn off 48V. 2.
Connect the CM25 MkIII to an XLR input on your Scarlett Solo using the
included XLR
to XLR cable. 3. Press the 48V button to turn on 48V phantom power. 4. Set
your input gain as per the steps in the section Setting Preamp Input Gain.
We know you’ll want to start recording straight away, so we’ve included a
simple (yet clever) mic stand to make sure you can get up and running even if
you don’t have a full set-up for your studio yet.
We want to ensure we aren’t being wasteful with our product design, so
challenged ourselves to create a mic stand from the packaging we were already
using.
We’ve reused the cardboard sheet inside the box, needed to protect your
Scarlett in transit, to create a mic stand to get you recording straight out
of the box.

Sample rate refers to the samples per second your computer is recording. The
higher the value, the higher the quality; however the higher the value the
more hard drive space your recordings take up. Often, using 44.1kHz is more
than enough for recording.
Note Some features, listed below, are not available at quad-band sample rates
(176.4 and 192kHz).

Examples of Use
Scarlett Solo 4th Gen Studio Pack User Guide
Connecting Inputs and Outputs
The following diagrams show how to connect a range of inputs and outputs to
the Scarlett Solo. To connect external processors, synthesisers or keyboards
see Connecting a Line-Level Device [33].
1. Connect instruments such as guitars, bass, electro-acoustic guitars and
other instruments with pickups to Input 1 the 6.35mm jack input on the front
panel. When you connect an instrument use a 6.35mm to 6.35mm TS mono jack
cable and set the input to ‘instrument’ using the Inst button.
2. Connect your headphones (e.g. the Scarlett SH-450 headphones) via a 6.35mm
jack to the headphone output. You must use a 6.35mm TRS jack connector to
connect your headphones. If your headphone jack connector is smaller you need
a headphone jack adaptor.
32
3. Connect a microphone (e.g. the CM25 MkIII) to Input 2 using an XLR to XLR
cable. You must connect a microphone via an XLR cable, other microphones may
not work, or you may have problems.
4. Connect monitor speakers (aka Monitors) to Outputs R and L (right and
left). Use 6.35mm balanced TRS jack cables to connect monitors. If your
monitors have different connections please see the monitor’s user guide.
5. Connect the Scarlett to your computer using a USB cable.
Scarlett Solo 4th Gen Studio Pack User Guide
Connecting a Line-Level Device
The following diagram shows how to connect a line-level device to the line
input on the Scarlett Solo.
Standalone Mode
The Scarlett Solo has a standalone mode; this mode allows your interface to
pass audio when it’s not connected to a computer. This can be useful for:
· Increasing the number of preamps on another interface or mixer that only has
line-level inputs left.
· To use your studio setup without having your computer turned on or plugged
in, for example, to use your guitar through your speakers, or any electronic
music equipment connected.
To setup Standalone mode:
1. Connect your Scarlett’s power socket to mains power. This can be a USB
wall plug, similar to what you may use to charge your phone.
2. Connect your inputs and outputs to your interface as usual (see Examples
of Use). 3. Turn on Direct Monitor to make sure the input signals are being
sent to the outputs
(headphones and line).
1. Connect line-level devices such as synthesisers, keyboards or mic preamps
to input 1 using a 6.35mm jack input on the front panel. When you connect a
line-level device use a 6.35mm to 6.35mm TRS jack cable but note the input is
mono. Turn off Inst when you connect line-level devices to the Scarlett Solo.
Loopback
With Loopback, you can capture computer audio and record it into your
recording software on separate channels alongside your connected mics or
instruments. To use Loopback select inputs channels 3-4 in your DAW software.
Loopback works by ‘looping back’ audio outputs from your computer to virtual
input channels within your Scarlett. Any computer audio can be recorded into a
DAW (Digital Audio Workstation).
Important When you’re using Loopback, mute the channels in your recording
software so you don’t cause a feedback loop.

Polar Pattern Chart
Microphone frequency response charts show how a microphone captures different
frequencies. A flat chart means the microphone captures all frequencies
equally, charts with peaks or dips mean the microphone is more or less
sensitive to some frequencies. We’ve designed the CM25
MkIII as an all-around microphone but it works especially well for vocals and
acoustic instrument recording.
Microphone polar pattern charts show how a microphone picks up sound from
different directions and at different frequencies. There are several polar
pattern types, the CM25 MkIII has a cardioid pattern. This heart-shaped
pattern picks up sound mainly from the front (0º) while rejecting sound from
the sides (270º and 90º) and rear (180º). This is useful for recording while
minimizing background noise.
