Audio Processing

This sub-menu is used to make changes that affect the on-air sound. It has five items: Select Preset, Edit
Parameters, Undo Edit, Save to Card, Save to Card as. The Omnia-3am style also has an Editing Mode item.
Select Preset
This opens up a selection box to select a factory preset or a user preset that was previously saved to the PC
Card. The name of the preset that is currently running is displayed. Use the jog-wheel to scroll through the list
to find a preset to load. Once the desired preset name is displayed, click the jog-wheel to immediately load that
preset into the unit's memory. This also returns you to the Select Preset menu item.
Note that once you move the jog-wheel to display another preset name, a message below the preset name
indicates the previous selection, i.e., "(was Jazz-6AM)" will be shown if that was the currently running preset.
This serves as a reminder, so you can reselect that preset in case you change your mind about changing presets,
since there is no way to "cancel" selecting a new preset to load.
A thermometer bar along the left side of the window indicates where you are in the list of presets. All User
Presets are added onto the end of the list, so they will be found when the bar is toward the bottom of the
thermometer.
Editing Parameters
Here you have detailed control of all processing parameters. Such parameters as attack/release times, gate
thresholds, multiband EQ settings and clipping drive are available through a graphical block diagram based
interface. The first blocks name, "AGC Wideband" flashes, indicating that it's the current parameter. To edit
the AGC Wideband parameters, click the jog-wheel. A list of the parameters relevant to that part of the
processing algorithm is shown (in this case; Phase Rotator, Wideband AGC, etc.). To edit another block's
parameters, rotate the jog-wheel until the desired block name is flashing and then click the jog-wheel. Detailed
editing is covered in more detail in Chapter 7, Editing Presets.
Undo Edit
Restores the preset state from before the last edit operation.
Save to Card
Saves the current parameters to the PC Card, overwriting any previous settings saved under the current Preset
name. This function cannot be used with factory presets, since they cannot be changed. If you have made
changes to a factory preset and wish to save them, use Save to Card as to save the changes under a new name.
