  • Page 101 VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER The Audio Processor page contains tabbed sections that allow managing of Orban presets. NOTE These tabbed pages (see Figure 2.2.50 on page 2.2.82 through Figure 2.2.62 on page 2.2.94 ) illustrate the many parameters associated with an Orban preset.
  • Page 102 VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Figure 2.2.50: Audio Processor meter window There are two types of Orban audio processor presets: factory presets and user presets. Factory presets, designated by an 'F' in the Load or Save screens, cannot be modified. When a factory preset control is changed, a new preset is automatically created.
  • Page 103 VX150 TO VX2 OPERATIONS & MAINTENANCE MANUAL OPERATING THE TRANSMITTER Tab Sections The following tabs (and referenced Figure numbers) are available on the Audio Processor page. Each provides specific control functions for the selected preset. Refer to the Orban Optimod 5500 manual for details on these settings.
