Chapter 4: Configuring Core Audio (Mac OS X Only) 31
Mirror Analog Outs 1 & 2 to Digital Outs (002/003)
This option is grayed out for systems using an
HDX card. When using 003, 003 Rack, 003
Rack+, Digi 002, or Digi 002 Rack, enable this
option to mirror the main outputs through the
digital outputs that are selected in the Hardware
Setup dialog.
Connect Button
The Connect button is available when the Avid
Core Audio Manager is launched and cannot
connect with the Pro Tools hardware (such as
when Pro Tools is launched and the hardware is
disconnected or disabled). Before trying to con-
nect, make sure to quit Pro Tools and make sure
that your hardware is connected and turned on.
You can then click on the
Connect button to ac-
quire the hardware.
Quit Button
Use the Quit button to quit the Avid Core Audio
Manger. Be sure to quit any client applications
before using the
Quit button in the Manager. If
any applications are currently attached to the
Manager application when quitting, you may get
an error message indicating that the Pro Tools
hardware is no longer available. You may have
to change the application’s preferences to use
different hardware for playback or possibly quit
and relaunch the application for proper play-
back to be resumed.
Configuring HD Audio
Interfaces for Third-Party
Applications
When using an HDX card with an application
other than Pro Tools (such as Apple Garage-
Band), you can configure hardware settings
using the audio preference settings available in
that application.
To configure hardware settings through a Core
Audio application (such as Apple GarageBand):
1 Select Avid HW (HDX) for Audio Output and
Audio Input.
2 Select a buffer size for your system from one of
the following options:
•Maximum/Large buffer size
– or –
•Minimum/Small buffer size
If any application is launched prior to
pressing the Connect button and you want
that application to use the Avid Core Audio
Driver for playback, you will need to quit
and relaunch the application for it to con-
nect properly to the CoreAudio Manager.
For more information about the hardware
settings options for your specific Core Audio
application, refer to the manufacturer’s
documentation.
