Installation guide
WARNING! There are certain changes that, if made on a live HAL device, cause a recompile of
HAL's DSP configuration: Wiring changes, addition or deletion from the Processing Map of I/O
Processing or DSP Processing blocks, changes to the maximum delay value in the Delay DSP Proc-
essing blocks. If a recompile is required, Halogendisconnects from HAL. We recommend avoid-
ing this situation unless you're sure it is what you want to do!
TIP: When making changes on a live device, it is certainly possible to inadvertently make
changes that you did not intend. Been there before? Therefore, we highly recommend that you
always maintain a backup configuration file containing the desired settings for your HAL.
NOTE: Halogen configuration files have an extension of .hal and, by default, are stored in
C:\Users\<user>\Documents\Halogen Configs.
NOTE: A Halogen configuration file includes a single HAL device (HAL1x, HAL1, HAL2, HAL3, HAL3s,
or HAL4) that you choose when creating the file. Once you have created a configuration it is not possible to
change the HAL model.
NOTE: HAL automatically mutes its outputs whenever a new configuration is loaded or applied.
The HAL Configuration Viewer
The Halogen software installer includes a small application that allows you to view basic information about HAL
configuration files without requiring you to open them from within Halogen. This application displays the file-
name, its location, the HALModel and the Halogen Version for the configuration file.
To run the HALConfiguration Viewer, first open the Halogen Configs folder:
Windows 7
Open the Documents window by clicking on Start Menu, then Documents. Next, view the HALconfiguration
files by double-clicking on Halogen Configs.
Windows 8
In Windows 8.1, right-click on the Windows logo icon in the lower left corner of the screen and select File
Explorer from the menu. Next, in the window that opens, double-click on the Documents folder, then double-
click on the Halogen Configs folder.
Now, view the information for any configuration file (.hal extension) by right-clicking on it and selecting View
HALInformation from the context menu that appears:
