To determine the project surround format
1 Open the Audio project settings by doing one of the following:
• Choose File > Project Settings > Audio (or use the Open Audio Project Settings key
command, default assignment: Option-U).
• Click the Settings button in the Arrange toolbar, and choose Audio from the pop-up
menu.
2 Choose a format from the Surround Format pop-up menu.
Tip: Save a project that has been set up for surround format work as a template. This 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.
Setting the Input Format of Channel Strips
The channel input format determines the mono, stereo, or surround status of the channel
strip.
The symbol on the button indicates the current status as follows:
Mono Left Stereo Right Surround
• Mono: One circle represents a mono input format. The level meter shows a single
column.
