Chapter 35 Working With Surround 813
Note: The surround format chosen here only alters the layout/routing of channels to
speakers in the assignment section. The actual project surround format is determined
by the Surround format Audio project setting (see “Setting the Project Surround
Format” on page 815).
To determine what speakers the Logic Pro outputs are sent to, do one of the
following in the Output tab:
m Choose the desired output of your audio interface from each of the active pop-up
menus; Left, Center, Right, and so on.
You can choose outputs that don’t exist for your hardware, allowing you to work on, or
create, a surround project with a computer that is not equipped for surround playback.
These are shown in brackets. As examples: (Output 17) or (Output 32).
m Click one of the three buttons below the Show As menu.
 Default: Click to activate the default setup of Logic Pro. As an example: For the 5.1
format, this means that output 1 is routed to the left speaker, output 2 to the right
one, output 3 is assigned to left surround, output 4 to right surround, output 5 to the
center speaker, and output 6 to the LFE channel.
 ITU: Click to assign the International Telecommunications Union standard, used by
many professionals.
 WG -4: Click to use the WG-4 standard, set by the DVD Forum for DVD-Audio.
To determine what inputs are used for each surround channel:
m Open the Input tab, and use the procedures outlined above for the Output tab.
