data. Different manufacturers’ products may interpret these codes differently and require you to set these bits by "trial-and-error" until proper operation is achieved.

CONSUMER FORMAT ADVANCED SETTINGS (Emphasis): This status bit is used to indicate if pre-emphasis has been applied to the outgoing digital audio signal. The default is "None" and rarely will any user want to set the value to "50/15uSec" unless the transmitted audio has been encoded with 50/15uSec pre-emphasis.

PROFESSIONAL FORMAT ADVANCED SETTINGS (Data Type): The user may assign the outgoing data as audio or non-audio data. Many devices ignore this setting. The obvious default is "audio," however, choosing “non-audio” is appropriate if you wish to send an AC3 signal (Dolby Digital 5.1 surround sound) out of the S/PDIF output. Some software DVD players are capable of this, as well as AC3 or Dolby Digital encoding software.

PROFESSIONAL FORMAT ADVANCED SETTINGS (Emphasis): The user may choose to indicate or not indicate if pre-emphasis has been applied to the outgoing digital audio signal. The default is "None" and rarely will any user want to set the value to "CCITT" or "50/15uSec" unless the transmitted audio has been encoded with one of those types of pre-emphasis.

Save, Delete, Load Buttons; H/W Installed

At the rightmost side of the Delta Control Panel are the Save, Load and Delete buttons as well as an "installed hardware" set of radio buttons. These controls appear regardless of what Delta Control Panel page is being displayed.

SAVE, DELETE, LOAD: The Delta Control Panel always retains the last settings entered. However the Save, Delete, and Load functions expand this capability to store different sets of control panel settings using different configuration file names. These configurations are then available for recall at a later date and time.

Clicking the ‘Save’ button brings up a dialog box prompting you to name the current configuration. Once you have done this, click ‘OK’, and your current configuration has been saved to disk. If you decide that you no longer need a particular configuration, click the ‘Delete’ button. Highlight the name of the configuration file that you wish to delete, and click the ‘OK’ button. To recall or reload a saved configuration, click the ‘Load’ button. Highlight the name of the configuration file that you wish to recall, and click ‘OK’. Those settings will now appear in the Delta Control Panel and the driver will automatically update the hardware.

H/W INSTALLED: Up to four Delta cards may be installed in a system at one time. This section displays all installed Delta cards, and allows you to select which particular card is under the control of the control panel software. To select a card for configuration, click the radio button to the left of that particular card in the “H/W Installed” list.
