Enabling the Orban Audio Processor for Preset Selection
Enable the Orban audio processor to allow preset selection using either the front panel UI (see
Orban Enabling - Using the Front Panel) or the remotely accessed AUI (see Orban Enabling - Using
the Remote AUI - see page 2-166) as follows:
Orban Enabling - Using the Front Panel
1. With the transmitter turned on and in local mode of operation, navigate to the front panel
UI's Main Menu -> User Settings menu. Select Edit Presets (see A in Figure 2.148 on page
2-166).
2. In the Edit Presets screen (see B in Figure 2.148 on page 2-166), select from the list the
desired preset for use with the Orban audio processor or create a new preset.
3. Within the selected preset's screen (see C in Figure 2.148 on page 2-166), scroll down and
select Main Audio.
4. Within the Main Audio screen (see D in Figure 2.148 on page 2-166), scroll down and select
Audio Processor. This option appears only when the transmitter has been configured for
Orban Inside.
5. Within the Audio Processor screen (see E in Figure 2.148 on page 2-166), select Enable.
From the Enable screen, select ON to enable the audio processor (selecting OFF disables the
audio processor)
Note:
Enabling the Orban audio processor locally will cause the remote AUI to display an enabled
setting. The same occurs on the front panel UI when enabling remotely.
Note:
The Orban Inside card processes only the main audio; however it is possible for the composite
SCA inputs to result in excessive modulation. The L/R limiter is automatically disabled when
the Orban Inside card is selected; however the other limiters (hard limiter, AGC limiter, 2-slope
limiter) remain active. Nautel recommends that you set the thresholds for these other limiters high
enough to ensure the signal is unaffected. These other limiters remain as a last resort to prevent
over-modulation.
