Set the surround format in Logic Pro for Mac
You choose the surround format you want to use for a Logic Pro for Mac project in the Audio project settings. By default, every new surround project is set to 5.1, and every new Dolby Atmos project is set to 7.1.2. For more information on surround formats, see Overview of surround formats.
Note: A Dolby Atmos project only supports three surround formats: 5.1, 7.1, and 7.1.2.

Tip: After you set up a project for surround format work, save it as a template. That way you won’t have to set the surround format every time you want to create a new surround project. Start with the included templates, modify them as necessary, and save them as your own templates.
