3.
In your DAW, make sure the input to your insert, or your send's return, is set to the
input on your Scarlett 4i4 you connected to the output of your outboard gear.
After going through these steps when you play your DAW session you should hear the effected
signal coming back from your outboard gear either inserted in the channel's effects chain or by
listening to the effect's return.
Tip
You can use the same process to reamp your DI guitar signals. Replace the outboard
effects unit with a reamp box and guitar amp.

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 5-6 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).
You can also use Loopback to create a mix of any audio sources on your Scarlett, instruments
connected to the preamps or audio from your computer. With Loopback, you can mix
instruments and backing tracks for your online concerts or balance your microphone and game
audio for your live stream. See
Focusrite Control 2 Mixer
Important
When you're using Loopback, mute the channels in your recording software so you
don't cause a feedback loop.

Standalone Mode

The Scarlett 4i4 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 has run out of
microphone preamps, for example:
• Using any spare line inputs on the other interface.
For example, by routing the Scarlett's microphone inputs to its line outputs.
• 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.
2.
Connect your Scarlett 4i4 to a computer running Focusrite Control 2. In Focusrite
Control 2 's mixer page route the Scarlett 4i4's inputs to the outputs you'd like to use.
See
Focusrite Control 2 Mixer
For example, you could route microphone inputs 1 and 2 to line outputs 3 and 4 to
use your Scarlett 4i4 as a standalone mic preamp connected to another preamp's line
inputs.

standalone mode.
