Apollo Solo USB Manual Working With Apollo Solo USB 59
Using Apollo Solo USB for System Sound I/O
Apollo Solo USB’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 Apollo Solo
USB’s 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
Apollo Solo USB is set as the audio I/O device in the OS, any audio software that uses
system sound will use Apollo Solo USB for I/O.
Important: To prevent system sounds from being inadvertently routed into Apollo
Solo USB’s outputs and/or DAW recordings, setting Apollo Solo USB 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 Apollo Solo USB for system sound I/O, audio levels are
controlled by the audio application, Apollo Solo USB, or both, as described below.
System Sound Output
Audio from the application is routed to Apollo Solo USB’s main outputs and mixed with
Apollo Solo USB’s input signals. The application’s audio level is controlled from within
the audio application, while Apollo Solo USB’s input levels are controlled within Console.
Note: To adjust the level of system audio at Apollo Solo USB’s outputs, use the
output level control within the audio application.
System Sound Input
The level of Apollo Solo USB’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.
