Apollo Solo USB Manual Console Settings 155
Hardware Settings Panel
The Hardware panel is where Apollo Solo USB’s system-level audio interface I/O settings
such as sample rate and output reference levels are configured. These settings are used
by DAW applications when they are configured to use Apollo Solo USB as the audio
interface. Even when Console is not open, these settings are stored by the Apollo Solo
USB drivers for use by other host applications.
Hardware panel
Sample Rate
This setting defines the sample rate that is used for Apollo Solo USB A/D and D/A
conversion and UAD Powered Plug-Ins processing. When using UAD Powered Plug-Ins,
higher sample rates require more UAD DSP resources.
Note: When the sample rate is changed, hardware relays that mute the outputs
are temporarily engaged to prevent audio artifacts. This action causes an acoustic
clicking sound that can be heard within the hardware. These clicks are by design
and can be safely ignored.
Host Control of Sample Rate
Behavior and control of the sample rate depends on the operating environment:
Without a DAW – Apollo Solo USB’s sample rate is set within Console when a DAW is not
used (when Console is the only host application).
With a DAW – The sample rate is usually changed within the DAW application’s audio
preferences.
Tip: Sample Rate can also be viewed and changed via Console’s Info Bar.
