M-Audio AP-012403 owner manual Audiophile USB Control Panel

On Macintosh: During the driver installation, a dialog box will ask you if you wish to place a shortcut to the control panel on your desktop. Clicking this checkbox will, upon completion of the driver software installation, place a shortcut to the Audiophile USB Control Panel on your computer’s desktop.The control panel program itself will install to your system’s hard drive. In OS 9, the Audiophile USB Control Panel will be placed in the Control Panel folder, which allows it to be accessed from the Apple Control Panel drop-down list. In OS X, the control panel is installed into the System Preferences folder.

If you choose not to place a shortcut icon on your desktop during the installation process, you may create an alias by highlighting the Audiophile USB Control Panel on the hard drive and pressing the Command Key+M. The alias may then be dragged to the desktop. The control panel can be launched from any of the above locations. Once the Audiophile USB Control Panel software has been opened, you will see the various controls for enabling inputs and outputs and for setting other parameters.

NOTE: When using a music software program that is ASIO capable, launch the Audiophile USB Control Panel software from within that program. If you need to change the master clock settings, for instance (in other words, change from the Audiophile’s internal clock to an external clock by selecting “S/PDIF In” from the control panel), it is desirable to launch the music program first, and then the Audiophile USB Control Panel from the program’s “launch” or “control panel” button. Without the music program open however, it is okay to open the Audiophile USB Control Panel from your desktop or other location.

When the Audiophile USB driver and control panel software are first installed, a “default” setting is created that will work for you in most circumstances. The analog inputs are active, as well as the analog outputs and the S/PDIF output. The S/PDIF Input is left unchecked. The “16-bit” radio button is selected, but can be switched to 24-bit if you wish to record at that bit depth from your music program. The Audiophile is capable of recording at sample rates up to and including 48000Hz.

You should only check the S/PDIF Input port if you are recording audio from the S/PDIF Input, or otherwise wish to synchronize to an external
