These specifications allow you to compare your Solo 4th Gen with other devices and make sure they’ll work together. If you’re not familiar with these specifications, don’t worry you don’t need to know this information to use your Solo 4th Gen with most devices
Where possible, we measure all performance figures following AES17.

Note
Outputs 1 and 2 share the same feed as the Headphone Output. Whatever signal is present at the line outputs, you will also hear from the headphone output.
Some Windows applications, such as Zoom, Microsoft Teams, OBS Studio, or web browsers, do not support the ASIO driver type used by professional audio software. Instead, they rely on a different style of driver that accesses the channels exposed by Windows in the Sound Settings.
By default, when you connect a Focusrite interface to a Windows computer a single Playback device and a single Recording device appear in non-ASIO applications.
To avoid confusion, using the Focusrite driver, you can choose which channels Windows should show or hide to these apps. This won’t affect how the interface works in your DAW (like Ableton Live or Cubase), which uses the ASIO driver directly.
Note
The Focusrite driver is installed with Focusrite Control 2 which you can download at any time from:
To show the full channel set to non-ASIO applications on Windows:
-
Click the Focusrite Notifier icon in the Windows taskbar. This opens the show/hide window.
-
Choose the channels you want to show to non-ASIO apps.
For example if you want to use line inputs 3/4 into streaming software, tick Analogue 3 + 4.
-
Click OK.
-
Open your non-ASIO app, you can now see each pair of input channels.
This does not affect ASIO apps
ASIO-compatible software ( most DAWs like Logic Pro, Ableton Live, Cubase, FL Studio, etc.) uses its own driver and will still show all channels, even if they’re hidden in Windows Sound Settings.
This means you can hide channels from Zoom or OBS without affecting your DAW setup.
