Tip
The 2i2 has XLR inputs at the back for microphones and 6.35mm (1/4") jack inputs on the front for instruments or line-level devices.
Using the front panel jack input(s) disables the XLR mic input. If you're not getting sound from your XLR input(s), ensure nothing is connected to the front panel jack inputs.
This section covers all the features on your 2i2 Anniversary Edition 's front panel, what they do, how you might use them, and how they work in Focusrite Control 2.
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 to 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.
To increase the input gain, turn the gain control clockwise. As you move the gain control, the Gain Halo gradually lights clockwise to show you the gain level. This diagram shows the gain at various levels:
-
No input gain
-
25% input gain
-
50% input gain
-
75% input gain
-
100% input gain
When you adjust your input gain while you send a signal into your preamp, the ring lights the same way as above but a colour, blue, amber, or red, shows how much level is going into your computer. Shortly after you stop adjusting the gain the meters revert to input meters (see Input Metering).
-
Gain at 40%, signal good.
-
Gain at 40%, signal pre-clip.
-
Gain at 40%, signal clipping.
-
blue 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.
You can also control the preamp gain remotely using Focusrite Control 2.
To adjust the preamp gain in Focusrite Control 2:
-
Click the virtual knob for the channel you'd like to adjust — or use the tab key to select the preamp gain control.
-
Move your mouse up and down, or use your keyboard's arrow keys, to increase or decrease the gain (in ±1dB increments).
The following images show the preamp gain at minimum, medium, and maximum gain.
|
No input gain |
50% Gain |
100% Gain |
This video teaches you how to control the gain from Focusrite Control 2.
When you're not moving the input gain control the input metering uses the entire Gain Halo. As the incoming signal gets louder (for example with a higher input gain setting) the Gain Halo lights from blue through to amber before the entire Gain Halo flashes red to show you the input has clipped.
This diagram shows the meters at different levels to show the input signal level:
-
No input signal
-
-42 dBFS
-
-36 dBFS
-
-24 dBFS
-
-18 dBFS
-
-12 dBFS
-
-6 dBFS
-
0 dBFS, clipping - turn down the input gain to avoid distortion and clipping.
Tip
If your signal clips the clip indicator at the top of the meter lights red. If this happens, select that channel and reduce the gain.
In the same way as the input meters on your 2i2 Anniversary Edition'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 blue 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 the value.
Tip
When you're recording, it's a good idea to aim for a -12dBFS peak level. This ensures you have enough headroom when you've recorded all your tracks.
|

Many front panel controls on your 2i2 are shared across the preamp inputs. The Select button moves the preamp controls to different inputs.
At least one preamp is always selected, to change which preamp(s) the controls are affecting, press the Select button. When you do this, the newly selected preamp's number lights amber and the preamp setting lights change to match the new preamp.
When you turn on your 2i2 the last selected preamp before you turned it off remains the selected preamp.
Linking preamps allows you to control two preamps simultaneously using one set of preamp controls. You can match gain controls for two preamps and enable other preamp controls. This is useful for stereo recording, for example, a microphone pair, stereo synthesiser, or keyboard.
When you've made the Preamp Link :
-
Both preamp numbers light amber and the Gain Halos light temporarily to their preamp level.
-
The preamp gain level is set to the lowest value of the newly linked pair.
-
The preamp settings are inherited from the currently selected preamp, e.g. preamp 1 is selected, therefore Preamp 2 inherits, Air, Safe and Inst settings from Preamp 1.
-
Changing any preamp setting changes the state for both preamps.
-
Adjusting either gain control changes the gain level for both preamps and is shown on both Gain Halos.
-
48V disables for both preamps.
To unlink preamps, hold the Select button for one second. When you unlink a pair:
-
The first preamp of the previously linked pair becomes selected and lights amber.
-
Gain levels and preamp settings stay the same, but you can now change them independently.
To link preamps in Focusrite Control 2, click the linking button in the top-right corner of the inputs page . In the pop-up you can choose which inputs you'd like to link or unlink.
When you link two preamps, the link icon appears at the bottom of both channel strips.
When you unlink preamps:
-
The first preamp of the previously linked pair becomes selected and lights amber.
-
Gain levels and preamp settings stay the same, but you can now change them independently.
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:
-
Connect your microphone, or another powered device, to an XLR input on your interface using an XLR cable. 48V is not sent to the 6.35mm (1/4") jack inputs.
-
Turn down that preamp's gain control to avoid any unwanted pops and clicks.
-
Press the 48V button (or the corresponding software button)
The 48V icon lights to show it is enabled.
48V phantom power is now being sent to both XLR inputs on your Scarlett 2i2 and to any devices connected to the XLR inputs.
To enable 48V (Phantom Power) from Focusrite Control 2 click the button on the input you want to enable it for. This is the same as pressing the 48V button on the 2i2's front panel.

Phantom Power off |
Phantom Power on |
Inst, or instrument, changes the impedance and input level of the 6.35mm (1/4") jack inputs on your Scarlett so the inputs sound their best for either an instrument or line-level source. We list the input impedance values in the Specifications section. If you don't turn on Inst and connect an electric guitar, the resulting sound can be muddy and quiet compared to with Inst on.
The Inst (Instrument) button only affects the 6.35mm (1/4") line input for the selected channel, either input 1 or input 2. It changes it from an input suitable for line-level devices to an input better suited for instrument-level devices.
To enable, or disable, instrument mode for the 6.35mm (1/4") jack input, select the channel and press the Inst button once. amber 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.
Note
When the Inst light is white, the 6.35mm jack input is at line level.
When Inst is enabled (amber) you can connect instrument-level devices to the 1/4" inputs such as, but not limited to:
-
Electric or electro-acoustic guitars directly and via effects pedals.
-
Electric basses
-
Acoustic instruments with pick-ups such as violins, double basses etc.
When Inst is disabled (white) you can connect line-level devices to the 6.35mm (1/4") inputs such as, but not limited to:
-
Synthesisers
-
Keyboards
-
Drum Machines
-
External Microphone Preamps
To change inputs 1 or 2 between instrument and line from Focusrite Control 2 click the Inst button once.

Note
When you switch between Inst and Line, the gain stays at the last level you set.
Auto Gain allows you to send a signal into your 2i2 Anniversary Edition (for example singing or playing your instrument) for 10 seconds and let the Scarlett set a good level for your preamps. If you find the levels aren't right, you can adjust the gain controls manually to fine-tune the levels before recording.
To use Auto Gain:
-
Press the Select button to move your preamp controls to the correct preamp.
-
Press the Auto button on your 2i2 Anniversary Edition, or the corresponding software button.
The Auto icon lights for ten seconds. The corresponding Gain Halo turns into a ten-second countdown timer.
-
Speak or sing into the microphone, or play your instrument during the Auto Gain countdown. Perform as you would while you're recording to make sure Auto Gain sets a good level.
If the Auto Gain was successful, the meter lights green before the 2i2 shows the gain value is shown. The gain is now set at a good level for your recording.
If Auto Gain fails, the meter lights red. Please see the section, The Gain Halo turned Red, for more information.
Note
Scarlett's Auto Gain makes sure your levels are set right not only using the input signal but also factors in:
-
The preamp's noise floor.
-
Digital silence.
-
Inter-channel crosstalk.
-
Unwanted knocks or bumps on your microphones.
This video teaches you how to use Auto Gain in Focusrite Control 2.
To use Auto Gain in Focusrite Control 2:
-
Click the Auto Gain button in Focusrite Control 2.
-
Speak or sing into the microphone, or play your instrument during the Auto Gain countdown. Perform as you would while you're recording to make sure Auto Gain sets a good level.
The Auto Gain process starts and the software Gain halo turns into a countdown timer.
If the Auto Gain was successful, the meter lights green before the 2i2 shows the gain value is shown. The gain is now set at a good level for your recording.
If the signal is unsuitable for Auto Gain (for example, there's no signal detected), after ten seconds, Auto Gain stops and the meters light red. The gain returns to the value you set before starting Auto Gain.

Hardware gain halo |
Auto Gain unsuccessful |
This can happen for all unusable signals, including no signal, very quiet signals, and too loud signals. If you see this error message, try the following:
-
Make sure you've connected the source to the correct input.
-
For condenser microphones, turn on 48V (phantom power).
-
Ensure you're making sound while Auto Gain runs.
-
Ensure the signal is not too loud.
-
If you are using the XLR inputs for a line level device (synths, keyboards, amp modellers), use the jack inputs instead.
-
Reduce the connected device's output.
-
-
If the signal is too quiet, increase the gain 25–50% before starting Auto Gain.
Note
To cancel Auto Gain, press the Auto Gain button again at any time during the process. The gain returns to the value you set before starting Auto Gain.
Auto Gain allows you to send a signal into your 2i2 Anniversary Edition (for example singing or playing your instrument) for 10 seconds and let the Scarlett set a good level for your preamps. If you find the levels aren't right, you can adjust the gain controls manually to fine-tune the levels before recording.
Multichannel Auto Gain starts the Auto Gain process for all the preamp channels on your interface. This is particularly useful for quickly setting levels for situations where you are using multiple channels simultaneously, for example:
-
Setting levels for yourself if you're playing guitar and singing simultaneously.
-
Setting levels for a drummer when you have multiple microphones on the drum kit.
-
Setting levels for a band recording 'live' together.
To start the multichannel Auto Gain process:
-
Hold the Auto button for two seconds.
The Auto icon fades between off and amber for ten seconds, and the Gain Halos for all channels turn into ten-second countdown timers.
-
Speak or sing into the microphone, or play your instrument during the Auto Gain countdown. Perform as you would while you're recording to make sure Auto Gain sets a good level.
If the Auto Gain was successful, the Gain Halos light amber before the gain value is shown on the Gain Halos for a second. The gain is now set at a good level for your recording.
Note
To cancel Auto Gain, press the Auto Gain button again at any time during the process. The gain returns to the value you set before starting Auto Gain.
You can also run multichannel Auto Gain from Focusrite Control 2.
To do this:
-
Open Focusrite Control 2 and go to the Inputs tab.
-
Click the dropdown arrow on the Auto Gain button.
-
Choose .
-
Auto Gain both starts running Auto Gain for all your 2i2 Anniversary Edition's channels.
-
Once Auto Gain has finished, Focusrite Control 2 shows the channels and their new gain levels:
Multichannel Auto Gain might fail during the process for one, multiple, or all channels.
You can either:
-
Click and all Auto Gain runs again for all the channels you ran Auto Gain for, even the successful channels.
-
Click close and run Auto Gain for any failed channels.
-
Click close and manually adjust the gain for any failed channels.
When you start Auto Gain on your 2i2, you must make a sound so the input can set the correct level. If you need a moment to get to your microphone or instrument, you can use Auto Gain count-in to add a delay before Auto Gain starts.
To enable Auto Gain count-in:
-
Go to Focusrite Control 2's Inputs tab.
-
Click the Auto Gain button at the top of Focusrite Control 2's Inputs tab.
-
Click to select a value for the Auto Gain count-in:
-
Off
-
5 seconds
-
10 seconds
-
20 seconds
-
30 seconds
-
Once Auto Gain count-in is on, the small timer icon in the top of Focusrite Control 2's Inputs tab shows the current Auto Gain count-in value in seconds.
Auto Gain Target lets you choose the level you want your signal to be after you've run Auto Gain.
You can set the Auto Gain Target in the Device tab of Focusrite Control 2's Preferences.
Auto Gain allows you to send a signal into your 2i2 Anniversary Edition (for example singing or playing your instrument) for 10 seconds and let the Scarlett set a good level for your preamps. If you find the levels aren't right, you can adjust the gain controls manually to fine-tune the levels before recording.
By default, Auto Gain aims to set your signal level to -18dB — this gives you enough headroom so when you add effects and record multiple tracks, you have enough headroom for your whole mix.
You can adjust the Auto Gain target level if your less likely to run out of headroom, for example if you're recording less tracks, using your interface in video calls, or streaming.
You can set Auto Gain Target to the following levels
-
-6dB
-
-12dB
-
-18dB
The Safe button applies Clip Safe, which automatically adjusts your preamp gain if you're at risk of clipping.
Clipping happens when your gain is set too high for the sound being recorded and your input overloads the preamp. A clipping symptom is preamp distortion, which is often unpleasant and can ruin a recording. Clip Safe helps you avoid this so if your input gets near to clipping, Clip Safe reduces the preamp gain, so you won't have to re-record your take.
Note
Clip Safe is only available at up to 96kHz, you cannot use it at quad-band (176.4kHz and 192 kHz) sample rates. The Safe LED lights red to show when it's unavailable.
To enable Clip Safe:
-
Press the Select button to move your preamp controls to the correct preamp.
-
Press the Safe button on the interface or the corresponding software button.
When you enable Safe, the Safe icon lights amber.
When you have two inputs selected using Preamp Link, Safe is applied to both preamps.
Tip
When you enable Clip Safe, your Scarlett continuously monitors your input signals, up to 96,000 times a second, and through a combination of analogue preamp adjustment and DSP, Clip Safe significantly reduces the risk of clipping.
Air lets you change your Scarlett's preamp sound with two different modes; Air Presence or Air Presence and Harmonic Drive.
Air affects the mic, line, and instrument inputs.
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:
|

Air Presence and Drive selected |
Note
Air Presence & Drive is only available at up to 96kHz, you cannot use it at quad-band (176.4kHz and 192 kHz) sample rates.
The Output control and Output level meter are related to the signals going to Outputs 1 and 2 on the back of your Scarlett 2i2, the outputs you'd most often connect to monitor speakers.
The Output control sets the level at the outputs from nothing (fully anti-clockwise) to full-scale output (fully clockwise).
The Output Level meter around the Output level control is a pre-fade meter (it is not affected by the control's position) showing you the signal level coming from your computer.
Note
On some occasions you may still hear sound from your monitors when the Output control is fully anti-clockwise, you can adjust your monitor levels to resolve this:
-
Turn down your interface's Output control and your monitors' level control.
-
Turn the Output control to maximum (or just below maximum).
-
Play sound from your system.
-
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 allows you to hear the signals coming into your interface's inputs without them going through your computer. This means you hear the inputs without any latency and without effects.
You might want to use Direct Monitoring for two reasons:
-
You're experiencing latency or a delay between making a sound and hearing it back from your software. By muting your software inputs and turning on Direct Monitor, you no longer hear latency.
-
You want to hear the clean unaffected signal going into your Scarlett, instead of listening to the software output, which may have effects and plugins changing the way your source sounds.
When Direct Monitor is off, the icon lights white. The Scarlett 2i2 has two different Direct Monitor settings, mono, and stereo, to enable Direct Monitor:
-
Press the
-
Press the
Note
If you're hearing your signal twice or getting a doubling or slightly phased sound, it's likely you've got Direct Monitor switched on, and you're hearing the sound back from software. You can either:
-
Mute the track you're recording to in your DAW software.
-
Turn off Direct Monitor and only listen to the sound coming from your DAW software.
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 the Mixer tab in Focusrite Control 2 and click the Direct Monitor software switch in the right panel. The switch lights amber and Direct lights amber on your 2i2's front panel.
|
Direct Monitor Off |
Direct Monitor on |
To adjust your Direct Monitor mix:
-
Open Focusrite Control 2.
-
Click the Mixer tab.
-
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.
Each mixer channel has several functions.
-
Mix Channel Name
This shows the mixer input's name. To edit the name, click the text box and type. You can use your keyboard's tab key to quickly move between channels.
-
Stereo/Mono Switch and Pan
The Direct Monitor Mode button between the channels changes the direct monitor mode between mono
and stereo
.
The Pan indicators on either side show where that channel is panned in the direct monitor mix. The pan is not editable and has two states depending on the Direct Monitor you select, centre (mono) hard-left and hard-right (stereo).
-
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.
-
Meter
This shows you the channel's level, in dBFS. blue 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.
-
Mute and Solo
Mute - Click the Mute button
to silence the channel in the Mix. The Mute button lights blue
when enabled. You can Mute multiple channels simultaneously.
Solo - Click the Solo button
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 2i2 Anniversary Edition 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 2i2 Anniversary Edition, we recommend using headphones with an impedance up to 300Ω.
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.
This section covers all the features on your 2i2 Anniversary Edition's back panel, what they do, how you might use them and how they work in Focusrite Control 2.
5V DC Port
With most computers, you won't need to use the 5V DC port. However, if your computer's USB ports can't provide 900mA, we've included a 5V DC port, so your Scarlett can be powered from the mains using a USB PSU.
The Scarlett 2i2 consumes a large amount of power. In some high-power situations, such as playing headphones at a high volume, some computers' USB ports may not be able to provide enough power and your Scarlett 2i2 may disconnect or the USB icon flashes red.
If you experience this behaviour, we recommend you use a mains PSU to power your Scarlett via the 5V DC port.
USB Port
The USB Type-C port labelled USB is to connect your 2i2 Anniversary Edition to your computer.
The connection to your computer provides USB power, two-way audio communication, and a connection to Focusrite Control 2.
The USB Icon Flashes Red
If the USB icon flashes red, this means your Scarlett 2i2 isn't getting enough power.
To resolve this issue:
-
Make sure you are using the original USB cable provided with your Scarlett.
-
Test a different USB port on your computer, make sure you're connecting directly to your computer and not via a USB hub.
-
If needed use the second 5V DC port on the back of the Scarlett 2i2. Connect a second USB cable from a separate USB PSU. Make sure you don't connect the power adaptor while you're playing audio.
Outputs 1 and 2 are line-level outputs to connect your Scarlett 2i2 to an amplifier or active monitors. The outputs are balanced 1/4" TRS jack outputs, you can use them with either unbalanced TS or balanced TRS jack cables and connect to speakers with 1/4" jack, RCA or XLR inputs.
Your Scarlett 2i2's front panel Output dial controls the level sent to Outputs 1 and 2.
Note
It is possible to use unbalanced connections, like TS 6.35mm jacks or jack to RCA cables– but we wouldn't recommend it. Using unbalanced connections, may mean you hear interference through your monitors.
If you hear a static, crackling or any other noise in your monitors, even when sounds not playing, make sure you're using balanced connections where you can.
The 3-pin XLR Input connectors are designed to accept at microphone level signals.
You can control your microphone level using the corresponding input gain control on the front panel. 48V phantom power is also available if you are using a condenser mic, you can enable phantom power using the front panel 48V button.
Tip
The 2i2 has XLR inputs at the back for microphones and 6.35mm (1/4") jack inputs on the front for instruments or line-level devices.
Using the front panel jack input(s) disables the XLR mic input. If you're not getting sound from your XLR input(s), ensure nothing is connected to the front panel jack inputs.
