Apollo Software Manual Chapter 9: Working With Apollo 161
Setting the I/O in the Operating System
If a software application doesn’t have its own setting for accessing a Core Audio device
directly, it typically uses the device specified in the “Sound” control panel of the OS
software. This sets the device for all system sounds, and any other device that uses the
system device for audio I/O.
Note: To prevent system sounds from being inadvertently routed into Apollo’s
monitor outputs and/or DAW recordings, setting Apollo as the output for system
sounds is generally not recommended when using a DAW.
Set the operating system’s Input and/or Output device to use “Universal Audio Apollo”
to route system sound to/from Apollo. This setup will assign system audio to the Apollo’s
default channels (1 & 2), which are routed to Apollo’s left & right monitor outputs.
