Focusrite Control 2 is the software you need to use to manage your interface. Focusrite Control 2 manages your routing, monitoring, mixer settings, and firmware updates.
macOS interface switching
If you're using your 18i16 on a macOS computer you can connect multiple interfaces and switch between them using the top-left tab in Focusrite Control 2.
This is useful for setting up multiple devices quickly. We don't support device aggregation.
Your 18i16 contains a mixer controllable from the Mixer page in Focusrite Control 2. You can use this mixer to combine and send input sources to your 18i16's physical outputs using the Routing tab.
The input sources to the mixer include:
-
Physical inputs
-
Analogue inputs (Instrument, microphone, or line inputs)
-
Digital inputs
-
-
Playback inputs
-
Output channels from your DAW software
-
Software playback from other computer software.
-
Once you've created your mix, you can send this to the 18i16's physical outputs to create a custom mix for your speakers, or an artist's headphone mix.
Viewing all your channels
By default, Focusrite Control 2 opens as a small window, to view more channels you can either:
-
resize the Focusrite Control 2 window.
-
scroll left and right within the tab.
The top bar of Focusrite Control 2's Mixer shows the different Mixes you have available listed as Mix A, Mix B, etc.
Each Mix allows you to combine inputs and send the mixes to outputs for different needs. For example, you may wish to use Mix A to listen to audio through speakers and Mix B for a singer's headphone mix. The singer may want their own vocals louder in their headphones, so you can increase the volume for Mix B only.
Tip
You can have multiple Mixes active at once in Focusrite Control 2.
Each Mix works independently, so, for example, you can route Mix A to your monitors and Mix B to headphones, without affecting each other.
Click a Mix to select it. You can now route it to any Output(s). To do this:
-
Click any existing Output, or the pencil icon
right of Routed to →
-
Tick the destinations you want to send this Mix to.
For example, you could send Mix A to Outputs 1-2, where you may have connected your monitors, and Headphones. You could then hear the same mix in your headphones and monitors.
-
Click X
to close the Mix destinations pop-up.
Above the mixer channels, you can see which Outputs your Mix is routed to. If you've not routed a Mix to an output, you'll see No outputs assigned.
Note
You can only feed each Output from one Mix. For example, you can't send Mix A and Mix B simultaneously to your headphones. When you're choosing Mix destinations, Focusrite Control 2 shows you if an output already has a feed from a different Mix. If you route the current Mix to an Output with a Mix already routed to it, it overwrites the routing to that Output.
Note
You can also change which outputs your mixes are going to in Focusrite Control 2's Routing tab, see Using the Focusrite Control 2 Routing tab for more information.
Loopback Destination
If you would like to record the specific input mix you've made, choose Loopback as a Mix destination. See Using your 18i16 4th Gen's Loopback feature.
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.
-
Pan
Moves a mono channel's position in the stereo image from left to right, or changes a stereo channel's balance from left to right. The default is centre. Alt, option ⌥ click, or double-click, to reset.
-
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. 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.
-
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.
In the Mixer tab of Focusrite Control 2 you can link or unlink stereo pairs of channels to make it easier to set up your mixes.
For example, you might link a pair of Analogue inputs if you had a stereo keyboard connected, or unlink software Playback channels if you had a two mono DAW channels sending to individual outputs.
Important
Linking channels in the Mixer does not link preamp channels. To link preamp controls, gain, 48V, Air, etc. see Linking Preamps
To change the link status of Mixer channels:
-
Click the Channels button in the top right of the Mixer window:
-
Tick, or untick, any channel pairs you'd like to link or unlink.
By default, Analogue inputs are unlinked, and software Playback channels are linked.
When you link channels, their channel strips and meters merge and one fader controls both channels.
Tip
In the Channels menu, you can tick or untick the boxes next to each channel name to show or hide channels in the Mixer window.
The routing tab in Focusrite Control 2 lets you organise what inputs and mixes you're sending to the outputs of your 18i16 4th Gen.
When you open the Routing tab, you'll see a list with columns for Outputs, Levels, and Sources:
-
The Output list refers to each output on your 18i16. There are sections for: Monitor Groups, Analogue outputs (line outputs, headphones) and Digital outputs (S/PDIF, ADAT, Loopback).
-
The Level control is exclusively for the analogue outputs. This lets you trim, or reduce, the output level by a set dB level, for example to level match speakers or avoid clipping external equipment.
-
The Source list lets you choose what to send to the corresponding output. Sources can be hardware inputs, DAW (software) playback channels, or a combination you've created as a Mix in Focusrite Control 2's Using the Focusrite Control 2 Mixer tab.
The Routing tab in Focusrite Control 2.
To assign a source to an output, find the output in the Output list and click the corresponding Source dropdown menu. Click a Source in the list to start sending that audio to the output. The meters to the right of the row show what you're sending to the output.
You can only feed each Output from one Mix. For example, you can't send Mix A and Mix B simultaneously to your headphones. When you're choosing Mix destinations, Focusrite Control 2 shows you if an output already has a feed from a different Mix. If you route the current Mix to an Output with a Mix already routed to it, it overwrites the routing to that Output.
If you would like to record the specific input mix you've made, choose Loopback as a Mix destination. See Using your 18i16 4th Gen's Loopback feature.
In the Routing tab, you can split stereo outputs to make two mono outputs. This lets you send them completely independent sources. You might want to use this if you're sending mono channels to outboard equipment, you have a mono speaker for testing your mixes.
To make an output pair two mono channels, click the stereo symbol in the box to the left.
The single stereo output expands to two mono outputs. Each output has its own independent Source dropdown box.
To revert to a stereo pair, click the mono symbol in the box to the left.
The 18i16's Alt (alternate) button lets you quickly route a source to different analogue outputs or change sources feeding a set of analogue outputs. This is useful for referencing your mixes on a different set of speakers, or referencing two different sources on the same outputs.
You can add any of the analogue outputs your interface has (excluding headphone outputs) to either Monitor group. For example, you could have Outputs 1-2 in Main and Outputs 3-4 in Alt to switch between two sets of speakers to check your mics. Or you could have Outputs 1 - 2 and 4 for a main pair of monitors and subwoofer in Main and Outputs 1-2, 3-4, 5-6, and 7-8, to check our mix on a Stereo setup and 7.1 surround set up.
Assigning Outputs to a Monitor Group:
-
Click the Edit button
above the group you want to change.
-
Tick the outputs you want to include in the group. You can remove outputs by deselecting them in the same menu. You can add mono outputs to a group after splitting them to mono in the Analogue outputs section, see Making Outputs mono in Focusrite Control 2.
-
Set the source for each output. Each output within a group can have its own source, for example, they could just be DAW outputs 1-8 for surround mixing. Or you could use a mix and include analogue direct inputs for a one-button way to turn on and off direct monitoring through your speakers.
Provided there is at least one output in each Monitor group, you can switch between which Monitor group you're listening to by pressing the Alt button on the front panel.
You can also switch the Monitor group you're listing to by using the Main/Alt toggle on the right-hand side of Focusrite Control 2.
Each individual analogue output has its own level control in the Routing view, whether it is in a Monitor group or not. To change the level for an individual output, click in the level box and hold, whilst dragging your mouse up and down. You can also double-click within the box and type a specific value.
The main Output dial on the interface controls the overall level of all outputs within the Monitor groups. The overall level of both Monitor groups is identical, however, you can use the individual output level controls to change the volume of one group vs another.
The Metering tab in Focusrite Control 2 lets you quickly see all meter levels for each input and output on your 18i16. The Metering tab is for looking at your levels only. You cannot interact with the meters.
The Metering tab has two parts. The top shows your Inputs. The bottom shows your Outputs.
Usually, you cannot see all meters in the Metering tab. Focusrite Control 2 lets you resize the window to show as many meters as your screen can fit.
Presets give you a way to quickly restore settings for your 18i16. You can change the settings to suit a particular session or set up and save this as a nameable preset. Next time you need to recall those settings, you can Load the preset.
Presets contain the following settings:
-
Input settings per channel:
-
Channel name
-
Input Gain
-
+48V
-

Note
Some features are not available at quad-band sample rates (176.4 and 192kHz).
-
Air Presence & Drive (Air Presence still works)
-
Clip Safe
-
Mix Sources
-
Coaxial S/PDIF

Optical S/PDIF
-
ADAT Channels
Clock source sets how your Scarlett synchronises in your set-up. Usually you'll set this to Internal, but if you're using another device connected to the ADAT or S/PDIF inputs on your Scarlett you may need to change the clock source.
The Clock Sources available are:
-
Internal
-
S/PDIF
-
ADAT
You can change your Scarlett's optical port to be able to receive either ADAT or optical S/PDIF signals.
The two options available are:
-
ADAT - use the Optical In/Out ports to receive/send ADAT signals.
-
At single-band sample rates, you can receive/send eight channels of ADAT.
-
At dual-band sample rates, you can receive/send four channels of ADAT.
-
At quad-band sample rates, the optical ports are disabled.
-
-
Optical S/PDIF - use the Optical In/Out ports to receive/send optical S/PDIF signals.
-
At single and dual-band sample rates, you can receive/send two channels of optical S/PDIF.
-
At quad-band sample rates, the optical ports are disabled.
-
The interface mode setting allows you to quickly change your interface's routing between using it as your main interface, connected to your computer, or using it as an ADAT expansion device with another interface.
You can use the 18i16's ADAT expansion mode with another Focusrite interface or an interface from another brand, if it has an ADAT input.
The two interface modes available are:
-
Main – In this mode, you're using your 18i16 as your main interface, connecting it to your computer via USB and selecting it in your recording software.
-
ADAT Expansion – In this mode, you're connecting the ADAT output of your 18i16 to another interface. When you select ADAT expansion the Routing is locked and changed on your 18i16 so the Analogue inputs are automatically routed to the ADAT output.
Important
ADAT Expansion mode doesn't change any Clock Source and Sample Rate settings as these depend on other devices in your system.
Note
In ADAT expansion, the routing is locked for most outputs, but we still let you choose the Headphones 1 and 2 sources. If your main interface has an ADAT Output this means you can send channels from your main interface to your 18i16 and gain extra headphone mixes.
A tick box to allow your 18i16 4th Gen to remember the 48V (phantom power) status after you turn off and on your device.
