Using Arrow For System Sound I/O; System Sound Routing - Universal Audio Arrow Manual

Using Arrow for System Sound I/O

Arrow's I/O can be used for the computer's system sound audio. System sound audio
I/O is used by music players, web browsers, system software alert sounds, and similar
applications — essentially, any audio application that doesn't access Arrow's
or ASIO drivers directly.
If an audio application doesn't have its own setting for accessing an I/O device directly, it
uses the device specified within the Sound control panel in the operating system. When
Arrow is set as the audio I/O device in the OS, any audio software that uses system sound
will use Arrow for I/O.
Important:
To prevent system sounds from being inadvertently routed into Arrow's
outputs and/or DAW recordings, setting Arrow as the output device for system
sounds is generally not recommended when using a DAW.

System Sound Routing

When the OS is set to use Arrow for system sound I/O, audio levels are controlled by the
audio application, Arrow, or both, as described below.
System Sound Output
Audio from the application is routed to Arrow's main outputs and mixed with Arrow's
input signals. The application's audio level is controlled from within the audio
application, while Arrow's input levels are controlled within Console.
Note: To adjust the level of system audio at Arrow's outputs, use the output level
control within the audio application.
System Sound Input
The level of Arrow's input signals being routed into the audio application are adjusted
with the preamp controls — and UAD plug-ins, if any — in Console. In this scenario,
Console's input faders don't control levels routed to the audio application. Signals routed
to audio applications are always pre-fader (Console's input faders control monitoring
levels only, not recording levels).
Tip: It's usually best to keep Console metering set to pre-fader (in Console
Settings>Display Panel) so the input meters accurately represent the signal level
at the audio application's inputs.
