Back Panel In Depth

This section covers all the features on your Scarlett 2i2's back panel, what they do, how you
might use them and how they work in Focusrite Control 2.

USB Connections

USB Port
The USB Type-C port labelled USB is to connect your Scarlett to your computer.U
The connection to your computer provides USB power, two-way audio communication, and a
connection to 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
If you experience this behaviour, we recommend you use a mains PSU to power your Scarlett via
the 5V DC port.

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.
Tip
The Scarlett 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.
