Windows Server 2003
If the driver has been downloaded from our web site, it has to be expanded
prior to the driver’s installation as follows: double-click on the downloaded
file (self-expanding). You can use the default destination location (Windows
temporary folder) or select another directory.
Important note
: this default procedure installs the ‘Digigram Hardware Settings’
control panel. This application allows the configuration of the hardware resources of
Digigram cards for all audio applications. The DHS allows for instance to define the
clock of the card, the input source, input and output analog and digital gain,
Sample Rate Converters, digital output format, etc...

The ‘Digigram Hardware Settings’
(‘DHS’) control panel
Digigram Hardware Settings (DHS) is an application allowing to configure the
hardware resources of Digigram cards for all audio applications using them.
This application is installed by default with the driver unless the command
line “setup x_topology” has been executed to install the driver.
A resource being managed by the DHS application can not be modified by any
other applications. To enable an audio application to modify a Digigram card
resource, this resource must not be managed by the DHS.
Note: As soon as a resource of a card is managed by the DHS, the clock
selection of this card MUST be defined in the DHS.
The DHS allows to:
• Select the clock the card uses
• Select of the input source
• Adjust analog and digital gains of inputs and outputs
• Enable Sample Rate Converters of an input
• Select the input monitored on an output
• Set the monitoring gains
• Define the digital output format
